- Amazing but could use work

This has everything. If you frequently use google or Wikipedia just use this instead it is so useful for such a wide variety of things, I use it mostly for STEM applications which it is amazing at. They added a camera feature which I begged for and I’m glad my pleas were answered it was definitely worth the $5. But here’s where it falls short, I still have apps like mathway because this does not accept mathematical input from images which I NEED in daily use. This would be the only math app I’d ever use if that was a feature. There is text recognition so I don’t think this is far out. Please add this and superb job on the app it’s absolutely amazing and worth the money.

- !!! Subscription Warning !!!

I would have give this app 5-star a couple months ago. However, I was only able to give it 2 (I originally want to give it 1, but at the mercy that it helped me a lot in the past). I paid for this app many years ago as it can request longer computation time and show step-by-step solution than the web version. However, this additional feature is curtailed after a recent update, and there is practically little difference of using this app now and the web version (maybe the UI is a little bit cleaner and user friendly, but remember this is a paid app, and now you have to pay for the subscription to use those features as you do with the web version). If this app is not for free, PLEASE DON’T BUY IT !!! Use the web version and it doesn’t cost you anything, your one-time payment makes no difference. If this is app is free, I would wish them to refund my money back, and I will probably give it a 4-star.

- Incredible

This app is amazingly good for STEM majors (science, technology, engineering, math). It is not a search engine like google as some of the other reviewers seem to believe. If you want to know what it’s like, the website by the same name is almost identical. Paying for the app lets you see step-by-step solutions to math problems, but does not give you access to the website’s same premium feature. You should know the step-by-step solutions are sometimes not helpful (e.g. often uses reduction formulas to solve trigonometric integrals, when students are generally taught to use those as a last resort). Still an amazing app though. I think many people that would like it would be content with just the free part of the website.

- Masters degree in your pocket

Anyone who gives this ap less than five stars is an ignorant fool. Absolute must have for anyone seriously committed to mathematical education by actually learning the material and actually working through textbook problems. This ap basically gives you the ability to automatically factor polynomials as you develop proofs thereby getting you to the end result step by step. Not for fools this is a tool for learning and man aid to developing formal proofs by allowing you to troubleshoot each step as you go without having to constantly reference tables of identities. Basically an abstract algebra calculator much cheaper than their full product Mathematica.

- Good information + Bad Subscription = WolframAlpha

Good information + Bad Subscription = WolframAlpha Please value the early adopters who supported WolframAlpha in the beginning by purchasing the app. The switch to a subscription model that limits the information available (i.e., step-by-step problem solving) is a bit disappointing to those who find mathematics interesting and paid to support the app. I used to be excited because app updates used to be upgrades. But like so many others, WolframAlpha has downgraded the app by pushing a subscription. I keep auto-update off all the time now since so many apps get worse each update. 😕 If you don’t mind forking over money each month via a subscription, then WolframAlpha is nice. If you just occasionally like to play with numbers, I can no longer recommend it.

- Sometimes problematic, but generally great...

I’m really glad I got this. My professor, for whatever reason, wants all solutions in y=mx+b format, but then assigns us a book that has the solutions in the back in Ax+By+C=0 format. Sometimes, it’s obvious that my solution is the same as what’s listed. Other times, it’s really not. This app helps me to check if I’m right or not and walks me through the steps to solve equations so I can see where I went wrong if my answer was incorrect. Sometimes it doesn’t understand my input. I really don’t find the input suggestions in the app to be helpful — they’re not specific enough. I wish that aspect of things were fixed. Otherwise, it’s a great resource.

- Needs easier design and Apple Watch interface

Searching with this app should render some great results based on what Wolfram Alpha's website states. Yet, it is not easy to search for information or get results that help to enhance my life. It seems like it requires a certain way to speak to it, in order to get a certain usefulness. While that may seem great for certain cases, putting the customer at the center of the product's usefulness will greatly enhance its reach and potential. I feel there is some real limits with this app. Especially with the inability to get detailed information using Siri and from Apple Watch. The app just isn't intended to provide a usefulness. You would think that chatbots would help to make the user experience even easier. But that may point to the lack of the company's willingness to play with creative ideas in expanding its usefulness.

- Love this app but

I have been using this app for years. Seeing the “go pro” come up with having advanced solutions, i decided to try it out. Did an in app purchase for a subscription based purchase and still keep getting asked in app to upgrade to pro. I hit restore purchases and i get a quick screen “thank you for your purchase” and again i go into the step by step solution and it is giving me “Basic solution” and having the pop up at the bottom AGAIN! “Go pro now”. I have cancelled the subscription immediately and now writing this review. Seems like some bugs here that need to be fixed....

- Give me back my privileges

Paid for this app years ago when it was just starting out on the app store. Always had access to full step-by-step solutions, as detailed in the description for the [then] paid version. Recently updated and got downgraded to basic privileges. What a slimy thing to do, the developers have no respect for those who helped get them off their feet. Since they replied to another review saying the same thing, let me say this to the devs: I will change my review back to 5 stars if you *choose* to make things right. If my review is still 1 star while reading this, then steer clear of the subscription and just use the free version — I paid and got downgraded anyways, so you might too. 100% comes back down to greedy devs, do better. I’ll bet my bottom dollar they’ll ignore this review too. So disappointed

- Improve 3D graph viewing

It would be really nice if you could type in a 3D function to graph and be able to manipulate the graph with multitouch. WolframAlpha is an amazing product. It’s right up there with IBM Watson and other incredible feats of computer science that I can have such a versatile and useful knowledge resource on my phone. Which makes it that much more shocking that you only get a single view of a 3D graph with whatever range and graph angle that Alpha chooses for you. Make a button to go into a detailed graph viewer. I don’t understand what is stopping Wolfram from implementing this. I hope that they read these and incorporate feedback into the product.

- Brilliant, period.

Without question, this app deserves a place on the home screen of anyone who occasionally needs a thorough answer to a technical question. What’s more, WolframAlpha is a dictionary, a fast calculator, a mathematics teaching tool, a de facto tutor, a superior substitute for Photo Math, and a great place to type in numbers for copy/pasting in other apps. If they’d add 3D Touch support, I will deem this app truly flawless. The service could use a spell check enhancement, but if you know how to type, you should be fine.

- Subscription warning is bogus!!

I use the free version of wolfram alpha online all the time. It does NOT break down the step by step procedure... for just 3 dollars this App DOES break it down step by step. So then there IS a huge difference between the free online version and this paid app. Again, for 3 dollars you will see the step by step breakdown for the math solutions... that’s a great price even though the subscription apparently gives you even more in depth breakdowns etc. This App IS definitely worth 3 dollars, other people are confused!!

- Ignore the 1 stars

I recommend that people ignore the one star reviews, those people have no idea how to use the app. They think this is some search engine like google but it’s more suited for running calculations. If you’ve heard of Mathematica and know what the wolfram alpha website is then you are basically getting full support with this app for peanuts compared to what the website charges. It’s not as mathematically powerful as Mathematica but for running quick calculations on the fly, this is indispensable.

- Name search crash

Generally, this app is stellar. Sometimes interpretation of search term can be unusual. But, certain name searches will crash the app. For example: Dana, Gerald, & Michael, to name a few. The search starts okay. Then the app crashes and a black screen appears. On an iPhone 6+, the device reverts to Home after the black screen. Even restarting the device or doing a name search hours or days later results in a crash. Lastly, the iPhone was checked out to be 100% at an Apple store.

- Best App for Computation Processes and so much more!

I’m a long time user of this app, and regret not rating it until now, although I have recommended it to fellow tutors and students in person and in online forums. I saw how this app was one of the first math apps to include the step-by-step operations of problems in Algebra I through Calculus III, Differential Equations, and Linear Algebra. And yet it offers so much more in the other sciences and even English vocabulary. I hope you’ll check this app out. It’s worth it and then some.

- Turned useless

I paid for the app years ago and understand the need for devs to monetize their work, but since I’ve used it so little I’ve hardly realized much value. For those of us who actually paid for the app initially, the ability to “go back” and see step-by-step solutions for say, the first X queries would be appreciated. I don’t need more than that. I recently discovered something was missing when I was sure this thing provided solving info and checked the reviews and discovered it had been changed. No need to keep this in its current form when I can just go to the website.

- It’s Like Google for S.T.E.M!!

This should be in the hands of every child. It is amazing to see the diverse data when searching topics in the fields of science, technology, engineering, and math. As a software architect, I plan to use the Wolfram Alpha API (Application Programmer Interface) and the Notebook API to build an Augmented Reality app. As a father, I want to build something useful for kids of all ages and grades. The goal will be to help them navigate this data to learn, discover and create. The in-app purchase to make the input accept images as well as text made me smile from ear to ear. I literally felt like a kid again, building a machine with the add-ons. They are totally worth it! Even with all the troubles we have in this world, I have not been this excited about the future as was when I saw the power I have in my hands right now.

- A review

The last paragraph is my previous review. With this app switching to a subscription model, it makes me think, why should I? There are plenty of free options out there and I probably to write my own app that does everything this app use to do without a pesky need for a subscription. This app has become a complete waste of my money and time. 1 star for basic functionality. WolframAlpha is a product that's a throwback, in a good way, to database searches. As long as the user sticks to keywords, the experience is enjoyable, and direct. There are search examples to learn from. Wolfram isn't going to be like google; but, if you know your keywords, it can be a lot more useful.

- Now a Pay to Use app...

I would have gladly given this app 5 stars, like another user mentioned. Back when I bought this app, all features were unlocked with purchase. But the fact that you have to pay for it, then pay for a subscription is not a fair practice in my opinion. I still give it 4 as it’s still really useful overall.

- Great for school

I use this app for school and it works great for math and stuff like that it will give the answers for most algebra and pretty much any simple math questions. Mathway is better if you need the steps to “show your work” but its a significantly more expensive app thats paid annually or monthly. Wolfram has a one time payment for the paid version so if your a student I would recommend it for sure.

- Majorly Helpful

Using this app for my college physics and calculus classes and it is a huge help. Gives more information on subjects and explanations than I can find on any other math calculator or search engine. I highly recommend for anyone with lots of questions that normally nobody understands! Also, I love the depth of information and intuitive view given on EVERYTHING. My go to app for questions!!

- Great Overall App

I’ve been using wolfram Alpha online for quite a while now. This app is perfect for me. It lets me use the full capabilities of Wolfram Alpha on my iPad along with step by step solutions at no extra charge. If you don’t want the mobile experience and step by step solutions you can use the web version on Safari for free, but in my opinion the three dollars is definitely worth the price.

- The Worlds Best Tool

This answer engine is the most amazing reference to search for truth and fact. Absolutely brilliant! I use it for my children with homeschooling and for my own self as I grow, heal and learn through life, and I use it for inspiration for my creative endeavors and spiritual questions. Wolfram Alpha is the biggest gift to the world and we should leverage this tool to figure things out and heal ourselves and the world. Thank you! 🤟❤️✌️

- Took my money now telling me i need to subscribe for the same features I already paid for

I already paid you guys my money for the app. You took away my access to it and now telling me I need to Pay for a subscription. GIVE ME BACK MY MONEY THEN!!! What did I pay you guys for the first time? How can you take my money and then take away the product that I paid for. This should be illegal. If you buy a pair of shoes and then Nike makes a subscription service they dont take the shoes away that you already paid for. This is absolutely ridiculous and I will never trust this company or their products every again. DO NOT SUBSCRIBE!!!

- Don't waste your expectations

I wouldn't guess in 3-4 weeks why it has high ratings, does really nothing, and I'm not even saying better or different from regular search, gives you some silly mostly useless stat. Furthermore, inputting can't perform any 2- or multiple-word search, if its not already inputted I mean, gets you an error with mean options to choose one of words from many inputted, combine couple and you get error again. Several other things, not even worth mentioning, no zoom, etc. And, its pricey too and in-app purchases to add photo check, etc. Not worth having on your phone, I'm deleting it

- So much information and computation easily accessible

As a physics and chemistry teacher, I routinely use Wolfram Alpha Pro in my classroom to help my students on projects with their data analysis. Such an amazingly wonderful tool for anyone with an interest in calculation and data analysis, or anything else in general. Getting the Pro version was worth every penny. Keep up the great work! Sincerely, Grateful science teacher

- By far worth the money

I'm a student who just is taking college classes instead of high school ones and this is a lifesaver. It will not only give you the answer, but a step-by-step guide to getting to that answer. Definitely a must buy for any students but calculus students especially. It will do everything from solving systems of equations to solving complex limits.

- Lucky me!

Looks like this crackpot hit the jackpot. I’m telling you (and you know who you are) you can keep the propagating these anomalies. There’s definitely data within the background noise. I don’t mean to make anyone jealous, however I just can’t contain myself. Simple rules producing seeming random complexity. All the richness life has to offer. The app? Yeah, it’s cool, too. Thanks for hanging in there with me on this review.

- Excellent tool for students

I’m going into high school and I’ve used this app for both 7th grade (Algebra) and 8th grade (Geometry). It has helped me immensely in regards to understanding graphing and geometric concepts, as well as in other projects, like programming. I’ve used Wolfram Mathematica in the past, mainly on Raspberry Pi. Most of the functionality of Mathematica is transferred over to this app (and for a mere $3!!). I can’t recommend this app enough!

- Just because you thought it would find you memes...

Folks, this is the most advance tool you will ever have access to. The ‘questions’ this app can answer are simple limitless. As many have pointed out, this is not google.... please grab this, pay the sub. fee and find out how amazing using these devies, and this amazing service, for knowledge can really be fun.

- Requires Internet Connection

I didn't realize this app requires an internet connection to be useful. Sure, it can do simple stuff like 1+2=3 without an internet connection. But I can do that in my head. I thought I would be able to use it to calculate derivatives and integrals offline, when I don't have access to the WA website. That would have been useful and I would deserve a 5-star review. But the simple fact that it needs an internet connection is kind of bogus. I can just pull up the WA website whenever I have an internet connection, why should I use this app??

- Best data app

Better than Google for most questions I have. Not just math. Want to know how the Sahara compares size-wise to the US? Avoid Google unless you really want to start being inundated with ads for travel agencies and expedition pants. Wolfram Alpha is my go-to app for data questions. Never tried it for philosophy, but I wouldn't be surprised to get those answers, too.

- Nice idea, less powerful than the online version.

I use this to just do sanity checks of definite integrals as I work. The app constantly computationally-times out before it can produce the result I need. However, the website has no problem analyzing the same quantity. I find myself coming back to this app less and less as it doesn't seem to handle very basic mathematical. I highly recommend the website. Especially since this is not a free app.

- Fantastic

I cannot recommend this app strongly enough. I am semi-retired, work a minion-type job (to stay busy) and I am always thinking Great Thoughts, a process requiring the occasional small datum. I regularly access this app for information and it has yet to fail. Even if the answer is not exactly what I am looking for, it creates other pathways to pursue the answer.

- It's worth the three bucks.

The app doesn't give you useless data, making it a streamlined way to search for random questions that enter your head. The user has to be able to construct good keywords, because he quality of input determines the quality of output. Overall, my new favorite way to look random stuff up.

- Garbage

Apparently this turned into some kind of graphing calculator that does your homework for you when I wasn’t looking. Stephen Wolfram had this TED talk where he claimed this was something else entirely. That’s why I paid around $5 for this, but it has NEVER done what was claimed. Now it’s marketed as some kind of homework cheating machine, I guess. I still wish it was the thing that Stephen Wolfram got up on stage and lied about. Every once in a while I think just maybe it’ll actually do that and I try. Nope! So I come here to recreate this grumpy review which gets repeatedly deleted when they update the app.

- Saved my Calculus Grade

The fact that I can use the app to see step by step solutions for only a fraction of the price to see them on the website is GODSEND. Unfortunately I downloaded this app near the end of my class and I only wish I’d thought to do it earlier. Highly recommend for checking your work for integrals and derivatives.

- Helped me pass calculus!!!

I paid for complete access to this app when it was first released- now it has moved to a subscription model after I already had access to the full app. This app is the only reason I passed my college calculus final... Must have for anyone taking an advanced math course!!! Best $3 I've ever spent on an app!!! This app does everything you ask and more... Can do ANYTHING with numbers as long as you know the correct way to input your query

- Even if you are not a STEM major

This is still an excellent app, with some improvements to how it runs on ios 11 and optimization for higher end iphones (8 8+ X) so that it can take full advantage of the phones processing power this app could easily earn my 5 stars (6 if the team decided to throw in a grammar auto-corrector)

- The subscription model is garbage

Like many other users, I bought the app a few years back for $5.99 to have the pro features. After updating a few days ago, all the pro features are gone and demands that I subscribe to get those features. The subscription model for software is none sense. I am not getting new content every day. It’s the same features. A one-time purchase fee is enough for software. Fixing bugs and pushing updates for the app is part of being a software developer. I refuse to subscribe to any software.

- Most outstanding free app worldwide

I have never asked a question that this app could not answer. Even if you make a question that it doesn’t understand it will make suggestions. This app is “free”, but if it was not free I would be quick to buy it. This is better than Siri or any other AI applications

- WolframAlpha app

This is by far my most used app and I have many. As a math teacher, I can easily check my answers or find all the steps needed to get the answer. I must use this app several times a day. It’s the best $1.99 that I’ve ever spent. And it’s not just for math. I would highly recommend this app.

- Best money I’ve ever spent

I cannot emphasize enough how great this app is. Literally any math thing I’ve ever wanted to do could be done so simply through this app. And it’s not just a calculator, it’s tools and logic language helps you actually come to understand what you are calculating. Just an incredible thing. Thank you Wolfram.

- Always useful

Not only does it do complex calculations, but it also interfaces with many databases of useful statistics ... like census and economic information. A particularly wonderful but is the way it parses a question, displays the results of the parsing, and extrapolates to answer a number of similar questions with tables and graphs. So much fun for a data junkie.

- Broken App + Money Pit

This app scammed me for over $10USD. I first purchased the app for $2.99USD. I tried to use it but the input keyboard is missing many functions needed to completely enter problems. Then I tried subscribing for $6.99USD with promises of a better input keyboard, step-by-step solutions, image recognition, expert customer support, amongst other things. After subscribing, none of these features worked. I feel scammed. Being a poor college student, I don’t have money to waste and this really made things difficult for me.

- Necessary for engineers, physics, math majors (college/university)

Amazing, well worth the price. Shows step by step solutions, just make sure to put everything in the function,eq,problem in appropriate format. (Usually Parantheses are necessary to isolate certain parts of your problem) ex f(x)=x^2-i(sqroot)(x-4)/(x^2-4) {no sqroot sign on basic keyboard, sorry}

- It’s come a long way!

I’m very pleased with what the app can do now. It appears to have all the functionality of the web app (at least for what I need to do - calculus)! I’ve been a Mathematica user for over 10 years and I highly recommend this app!

- Reference source..

I’ve used this app over the last number of years with great results. It is a very quick source of information that you need at the that moment, and smaller than a oversized reference book.

- App Restored

WolframAlpha has worked flawlessly for many years, until a recent issue. It has now been fully restored. There was no app update needed, since it seems that it is software as a service as well.

- Started Disappointing, Became Unusable

I paid money because I think of Wolfram as knowing what you're asking and managing to answer it. With constant chances to use it, I realized that WA often misunderstands what I'm asking or fails to provide needed context regardless of how I phrase the query. Once the app stopped opening, my opinion fell a lot more. It's been several days since I managed to open the app at all. It always crashes on opening now. I still use Siri to answer questions.

- Offline Mode

It’s good but needs a way to go offline and is the reason why I bought it, because I thought it could go offline ☹️☹️☹️

- Disappointed

Purchased this and a subscription only to find out it can’t compute simple integrals so I can check my university work. Was hoping for step-by-step instructions with the paid $9.99 a month subscription but even the $9.99 subscription a month does not have enough ‘computation time’. So, just a fore-warning for anyone subscribing to this service. The step-by-step instructions issued by the cloud are a maybe depending on how many steps there are, no matter how much you pay. It’s a cool gimmick and definitely has some amazing science behind the scenes. But for me the $4 for the app and $10 for a subscription only to be told ‘sorry you haven’t paid enough but you can roll the dice again with our more expensive subscription’ is a little disappointing.

- Frustrating user experience

The technology behind WolframAlpha is amazing and it’s a great tool to check your work against as a way of confirming your understanding of a mathematical concept. Typing equations on mobile is made so much easier with the in-app keyboard. Unfortunately the app constantly forgets my pro subscription and computations seem to take much longer than they do on the website. On the site the step by step tool is incredibly useful, but in the app it’s a slow, buggy mess. In its current state, the app’s only useful to me for typing in equations. If the keyboard was accessible outside the app then I would be happy just using the mobile site. At the moment I copy-paste from the app to the site, which works but is kind of annoying. Given the glaring bugs here, the app itself seems more like a channel to increase subscriptions rather than a tool providing better mobile access to WA.

- Using over 10 years most useful and underrated app out there

If you seek general information or specialist knowledge Wolfram simply puts google and wiki to shame. You have it all here and then some, highly recommended.

- absolutely positively frustratingly useless

as the subject says, takes every opportunity to misinterpret locations no matter what brackets, commas, parentheses or other ways I try to make the bleeding obvious.... It's capacity for Australian locations is absolutely nill so I doubt outside of US you'll fare much better. So your self a favour, give this a miss and save your self days of frustration. I tried feedback a few times all to no avail.

- This app knows everything

This app knows everything. If only it could go offline.

- Really curious but only US statistical data

This app and search engine is really interesting, but didn't show me anything for unemployment rate in my country.

- Shame it's so USA-oriented

I like this app, it's fun and informative, but some of the results are overloaded with USA data. Maybe this could be tweaked, considering the app is in App Stores outside the US.

- Truly amazing app

This app is very useful in day to day life, but it also bring quality. I recommend this app for all. Very nice.

- I haven't cried once since starting my math homework whilst using this


- quirky but brilliant

I now know how many goats are in Australia (estimated). And elsewhere. Very useful for conversions especially American to SI eg pathology values.

- Great for year 12 Math Methods

The step by step solutions are really useful

- There are better apps for free

This app not only costs money, but you must pay extra money just to unlock a ‘camera scanner’. A free alternative is photomath (which is pretty much the same without the complexity).

- Great app

Really helpful across a range of topics

- Excellent mathematical tool

Wolfram have provided an excellent mathematical tool

- How I passed uni physics

This app saved my life at uni.

- knowledge is power

as the title says

- Five!


- Wonderful, astounding power, so very useful.

I left school/university many years ago. So many functions and similar formulae have been lost in the mists of time by now. Yet, I need to check them from time to time. This marvellous app allows me do to such checks simply and efficiently! No more hunting through old text books to find a formula, then hope you punch the data into a calculator correctly for the RIGHT answer. Wolfram Alpha does it right first time, all the time! Just wish u could purchase a stand alone version for my MacBook Pro rather than have to be locked into a monthly fee. Hate software paid for by monthly fee,

- The better you get the better it gets

Invaluable help for my University maths and physics, the more I learn the greater seems its capacity to help. Same goes for using the app, for the novice there's a steep learning curve for data and function inputs, but there plenty of categories each with suggested searches, and for every search a cascade of new searches. The special keyboard is much better than the web based Alfa Pro version, however if you are paying for Alfa Pro ( as I was for a while) none of the interactive features of the web base Alfa Pro are useable via the iPad app.

- Don't judge by the limits of your ignorance

The financial functions alone are worth >$50 because even a trusty 12C can't calculate stock correlations, efficient portfolios, alphas and betas. When one adds the rest of the world's computable knowledge (eg: taxonomic webs for species, linguistically valid anagrams, weather forecasts in crisp detail, to take a tiny slice) this app is brilliant and priceless. Unless you are a polymath - and sadly there are none of them left - you cannot know what you are missing with this until you use it.

- Utterly Brilliant

This app has been more useful than I could possibly explain. It provides such an extensive array of knowledge, and can help with almost any question/problem you have. Being a university Maths student, it is just amazing for helping me in more complex problems, even going as far as to describe every individual step it takes to arrive at an answer. I love it, you will never regret this purchase.

- Fantastic app for anyone with a thirst for "all the answers"

Absolutely fantastic app, I used to have a series of apps (reference apps, encyclopaedic apps, unit calculators, health calculators, etc and the list goes on which were all replaced by Walpha. I would recommend this to anyone, it can tell you anything you need to know and answer/resolve problems or debates from math and physics to pop culture and celebrity.

- Incredible

The shear scale of the information available is mind-blowing. On top of that, so is the quality of the information. You can't type a specific calculus problem into google and get a step by step guide to the answer, but with Wolfram you can. Stuff like this makes me proud to be any part of science.

- Amazing

Using an iPad in high school can get pretty confusing, having to have several apps for different things, having to pay money here and there. This app is amazing, especially the show how to work out math feature. Would recommend to any student.

- Staggering achievement!

A must use app everyday. Once there seemed to only be Google, but W-A goes beyond the bent and tainted knowledge found on most of the Internet and reveals, for the first time, an Expert System of knowledge you can rely on. For a meager cost- there is, in your pocket, a forever growing encyclopedia galactica plus real and immensely qualified people behind it.

- amazing

I am doing University level engineering, and this app is an absolute must. It is fantastic for helping with complex problems, as well as checking ones I have already done. I cannot possibly live without this app It is a must for anyone doing maths and engineering type degrees/courses/whatever

- Great.

Pretty awesome if you are doing a maths or science course. This thing has lots of formulae, documentation, calculations and general information on a wide range of subjects and areas. Pretty good when you cant get a straight answer from your calculator (say, for an integral or something). Definitely worth the money.

- Simply amazing

The sheer wealth of information offered by this app is awesome. The data is American and a units option should be added however anything and everything can be found out with this app which makes it extraordinary value.

- Nice app!

Ok, I am not a professional in any scientific area, but I do need some solid facts about something from time to time, and with Wolfram the results are just great! I could alway get some answers out of expectation- in the good way:) This app just keep me wanting to know everything!

- Outrageously awesome

Sometimes you just don't have the time to do a quadruple intergral, wolfram makes it easy to get quick and reliable answer to your mathmatical needs. The handy and surprisingly broad array of availible information makes for fun coffee table conversation.

- Best app of all time.

Hats off to you Wolfram. This is one of the greatest apps I have ever bought, well worth the $3. You can use this for anything, maths, science, geography, history, even for fun. Would recommend to any senior high school or uni students for sure.

- Absolutely unbelievable.

Quite possibly the best, and most criminally underrated app I have ever purchased. Presents a solid 5 minutes of google searching in a matter of seconds. Would happily pay $10 for this.

- WofframAlpha

I use it for Maths. It works for lots of things but there is not much information available on inputing format. This means I spend a lot of time typing in mathematics to get Wolfram doesnt understand or a formatting different from what I intended. Using logs to bases onthere than e is an example. I have not had success in entering such expressions. Its good but users need more guidence.

- Superb!

This is a powerful app that is quickly going to become a 'must have'. The results are very quick. The learning curve small and the uses endless. For anyone wanting to create infographics this is amazing.

- Saved myself hundreds of dollars

This app features heavily in Siri on the iPhone 4S, and now I have access to it for a very small price 😄. What would be nice for me would be a forwards and back button.

- Amazing

Stumbled upon this app, since has made a number of other apps redundant. I'm floored at how easy and precise it is to use, that and the additional information returned is fantastic. Well worth a look.

- Amazing App

Works perfectly, has an incredible amount of knowledge on it and have found the step by step guide to solving maths problems so helpful. Definitely worth the money

- This is a must have resource application

The practical use this application gets on almost everyday of my life does not match it's price, this is a gift to the world and I am very thankful for it.

- Amazing!

It's such an amazing app! It is mind blowing what this app can do! I found out so many things, and I even use it to help me with my college-level maths and chemistry homework! It really is worth every cent!

- Mathematical Life Saver

I absolutely love the this app. It understands what you type in so well and interprets it just right. It can solve pretty much anything and is so useful for maths homework and investigations!! Well worth my $4.49!!! :)

- Great App!

Love it! Only got it today but can see how useful it can be. Only limitation seems to be a lack of Australian data. Hope that this is added soon.

- Awesome / unusual

This solid app gathers data that helps me understand topics from new points of view. Try out the website first to see if it meets your needs.

- Best app ever

This app is revolutionary ! It as an infinite data bank of informations on all of what you can think and even what you cannot think of ! Just crazy !

- Brilliant!

Tried a few search's and only one time did it not produce a result so re-worded my question and answered it (with more info than I asked for)....

- Genius

Brilliant, yes it is $2.00, and the website is free, but this is much simpler and quicker. Computes almost anything you want. Just a pity you can't use it offline.

- Not good.

The thing is. Is that you can go to the wolfram alpha website online and ask all the questions for free. Why do we need is app if it needs an Internet connection, it's just an Internet browser therefore. So you are paying 3 bucks for an Internet browser. Ridiculous!

- Wolfram alpha is great!

Cannot recommend this app more for anyone taking maths! Great time saver for checking answers and pinpointing where you went wrong.

- Outstanding

Only discovered it after interacting with Siri on the iPhone. What a fabulous resource!! Where has it been hiding? Well done guys

- Just brilliant.

Makes an extraordinary amount of information available.

- A student’s or a lifelong learner’s best friend

I’ve been using this app, off and on, on the web and now through my iPhone for a long time. I cannot stress how important this app is. I’d like a subscription feature, though the app and have an option to get PRO features, through the app, please and thank you.

- Life Saver for Calculus Help ❤️

Will give you step by step instructions for derivatives and integrals that are easy to follow, worth the money just for that feature alone.

- Cool IOS App however...

It would be cool to have an icon change option because it is too bright and colourful to have on the homepage. As minor as it is it one of the few apps that still hold onto its old look and another option would be ideal. Aside from that it is a useful app but quite slow as well.

- Very outdated

Many things are not there. For example, can’t inform me about anything related to Machine Learning, Data Science or even Gestalt Theory. It doesn’t return anything related to Settlements in Palestine. I found my free friend Google a much better aid in my research.

- Not as good as I'd hoped

Interesting app, but I'm having problems asking the question to get results. I also got the second party guide. Trying to find "Philips Vue lights" ( without the quotation marks), for instance, tends to break up the words and ask which word I want to look up. This does not get me shopping advice (as it is supposedly should) - just definitions of each word. Some queries are easy ( eg. "Highest Montain" gets to detailed info about Everest), but even after watching several videos and reading the guide I can't always get the expected results. I'm hoping to learn more about how to ask the question properly, but I wish there was a help area in the app itself that could help. Siri seems like to understand questions better than this app. When a search brings up a picture it's often very small and you can't zoom the screen or make the picture larger. Overall, it's a good app but it still needs some upgrading.

- amazing!

great app, does everything!

- No step by step solutions

What happened to the step by step solutions? Why does this requires a subscription now?!

- Not working great

Won’t compute certain integrals on the app but when I type in the exact integral the same way on the website, it works

- A great find.


- Not as good as I thought it would be

It can’t answer even the slightest of broad answers

- Good start!

I do not have a math or engineering background so I'm probably not the target audience. At $50 it's way too expensive for someone like me but the current $20 sale price is much more likely to draw customers. I'm impressed with the results it delivers but at the same time I wish it was better at interpreting what I'm trying to ask.

- Way Worth it

This is so much better than photo math! Honestly it’s worth the really small payment (especially when compared to the monthly payments from other apps) and I find its step by step instructions more thorough than other apps as well. If you're in higher-level math of any kind ( you can even do some analysis problems on this) I would recommend this software over any other.

- Fantastic

My number one go-to tool for economic and statistical data.

- Great reference tool

I’ve used it hundreds of times to look up data, data trends, and qualitative information on image files. Excellent data access to publicly available information.

- Crashes

Crashes on iPhone 6s when starting for some reason. Reinstalled to fix it

- App No Longer Opens

The app immediately crashes as soon as I click on the app to open it. The app worked perfectly before, but now I can’t even access it.

- Money stealers

I expect that when I buy an application I don’t need to pay more for access to the services I wish I could refund it :(

- Worth to go pro

This is powerful even good enough for varsity level use and been tried it is awesome .hope for more functions

- Goodbye, money grabber! Deleted the app.

Nice update to bring the feature of subscription. Bought and use this app for years, but deleted it today. This app not improved much during years but starts seeking money from customer. Good bye.

- The App to go to, for Facts.

When it comes to finding out information, there are a few trusted websites one can go to on the web. Among the top, is WolframAlpha!

- Horrible update

Serves me right for updating apps. They will always find a way to try and squeeze more money out of you. Now the steps to the solution have random blue boxes that hide answers and prevent you from seeing steps. I’m sure the Pro version clears it up right? I already paid for this app, it’s disgusting that Wolfram decides to screw us all over by trying to charge more for functions that previously existed. Sleazy bait and switch. What a shame.

- New version is trash

The new version sucks, now you have to pay way more in order to get step by step solutions. It's now a monthly subscription where in the previous versions it was a one time payment.

- Edit


- Sometimes useful

The handful of topics that it knows about are reasonably covered, but it doesn’t know about very much.

- Fantastic!

Absolutely love this app. Anyone who complains clearly doesn’t know its full potential or how to use it. This is NOT just a calculator - it does a heck of a lot more. Some folks say it is slow. Not sure what you expect considering all the results it gives you. I use this app on a regular basis and enjoy it immensely.

- Great app

I find this more and more my go to. Particularly for mathematics.

- Wonderful for Math!

I have only recently started using this app. However, the step-by-step instructions it provides for solving absolute value equations seem quite useful.

- no tide data from british columbia

no tide data from british columbia the marketing screenshots in the app store show ability to view tides

- Ugly and slow

This is a terrible app. It’s poorly designed, returns results ridiculously slow and overall just a major disappointment. Would not recommend considering the price.

- Removed the step by step

I bought this app because the reviews said that it featured step by step for solving equations, which was true for a short while but they removed it, rendering this as a fancy calculator but no longer a good study aid. Id give it a bit of a higher note for the encyclopedia part but it usually crash after a few second on my admitedly deprecated iphone5

- Keeps on quitting

Worked fine to begin with now every time I try to search for something, it half loads then closes the app. iPhone7 and totally up to date

- Awesome! Thanks!

Small bug: crashes when saving QR codes on iPhone 7.

- A+

Works well for me. Though I’d really appreciate the inclusion of archaic definitions of words. With that, this would be my definitive dictionary but until then I’ll have to stick to paper.

- Excellent

A very smart app.

- A Gem

Indispensable Mathematical tool for learning, research, and your next project

- 10/10


- The keyboard has lag

The keyboard doesn't work fluently.

- omg

I got lady wood when I saw the price for this thing at $1.99. This is such a useful application! -a very happy physicist

- Fantastic engineering but

It needs some nav buttons. That is the only flaw I can see.

- Too expensive for what's there

Delivers as advertised but too expensive for what's essentially a glorified browser. Does not work in airplane mode even for all that money.

- Just a headless browser app

This app is nothing more than a headless version of the browser based web-application. The only difference is the browser based application is free. Lack of internet access disables this application.

- invaluable resource

As a student studying math/physics, I use Wolfram Alpha and Mathematica on my laptop all the time, and had been wanting to get the app as well. The previous price was too high for me (I would rather just use the web interface), but at $1.99 it is definitely worth it. It is really intuitive to input math; it always understands what I am trying to say and the specialized math keyboard is great. I use this app all the time to check my calculus problems, plot functions (which it does WAY better than my TI graphing calculator) and compute things quickly. It will do any math related thing you can think of - including generating fractals and calculating eigenvalues of matrices. Impressive!

- Excellent and great price

Much better than going through to their website which I was doing till they finally reduced the price. It is now worth every penny.

- Ripped off

Wow I paid 20$ for this app and now it's only two bucks BS

- Undeniably useful

I'm not sure what p00psicle is saying with giving this app 1 star... clearly he/she doesn't know the benefits of wolfram. Not only will it solve any type of mathematic equation, but it shows the steps aswell. This app is unreal, and it helps me with my homework on a daily basis. Try the website out before buying if you don't believe me...

- Superb

Anyone remember the days when a pocket calculator was expensive? This app is 100 times more powerful, and only costs $1.99 - well worth it.

- It is an excellent apps for just $1.99.

I have waited for a long time until it drops to this price. Now it becomes the top three paid apps. I found from the web, people paying old high prices can get full refunds. Even no need to pay $1.99. They are very generous. Thanks.

- Crashes on os 4

Doesn't work on I os 4

- Won't open!

App doesn't open after I got the OS update. I payed for this app! Update the app to make it compatible and get 4 stars, or give me my money back!

- In Response To Jimmy DaPooh's Comment

I was skeptical to buy this, especially with Jimmy's comment. But, it seems his assumption is wrong. You CAN copy text and paste them elsewhere. You CAN copy images and/or save them (no screen-shotting required). You CAN take results and paste them for further searching. Sure the feature isn't thrown directly into your face, but I'm sure if you're an iPod Touch and/or iPhone user, it's common knowledge that pressing and holding on the screen brings up a menu for copying text/images! Same thing goes for this awesome app. Copy text? Yup. Copy images? Yup. Paste them somewhere else like the notepad app or into an email? Yup. Use results in further searches? Yup. Hopefully Jimmy DaPooh sees this post and changes his comment/rating to something this app deserves. They also have a video you can watch in the app showing you some of the cool things you can do with this app. I'm totally blown away. I wonder how they were able to compile all this information in such a versatile and variable manner! I just got this app today and it impressed me so much that I just had to write this review (especially with Jimmy DaPooh's false assumption). GET THIS APP!!!

- AP Calc Necessity

Suggestion: create a standalone keyboard app with all the math symbols. It would be perfect for teachers who use an iPad to teach Calculus but can’t type the math problems without an advanced keyboard like the one in this app. Hope this becomes a reality and helps teachers. -AP Calc AB Student, huge fan of this app

- Extremely helpful!!

This app is very helpful. It not only provides and answer but it also provides a great explanation of how that answer was found. Anyone in any kind of higher math I would definitely recommend!!

- A TI-84 on your iPhone

I’m going through a Physics text book and I’m using this app instead of a super expensive graphing calculator. I wish I would have had the option ten years ago when I was in college last.

- Lost me with the subscription

I like this app, and use it fairly often in the planning stages of projects. I wouldn’t have minded (at all) buying a one time in-app purchase for new functionality. Locking all new features behind an almost 70(!) dollar a year subscription is a deal-breaker. I can move to other programs like socratic and desmos. 70 bucks can buy a whole lotta apps from good developers with reasonable prices.

- Not just for STEM folk

This elegant computational machine isn’t just for math majors. Its emphasis on organizing and displaying the road to its answers (try checking the inflation-adjusted amount the next time you see a “it only cost $2 in 2000” sort of comparison), and its broad subject coverage, make it a treasure for everyone.

- Best App Ever

I’m not even a leave a review type of guy, but I have to let it be known. This is the most amazing informational app on the planet! *looks at google* The planet! Anything you want to know it gets down to the details in seconds.... it’s well worth the purchase!

- Very useful

A teacher recommended this app to me years ago and I’ve been passing it on since. You never know what you may need to calculate in every day life. This truly helps get you the answers and saves you the headache. Love it!

- The best for knowing everything!

You can you this app for anything. If you want to know more about a car or a certain math problem it will let you know. I highly recommend this app!

- Amazing utility!

I have been using this app for years and felt it only appropriate that I show my appreciation for the many times I needed an answer to various analytical questions. Thank you for this great app and for your teams continued work.

- Early Adopter now SHIRKED

As title says... took a chance early on... to be sure I paid a pittance but still... I PAID, am a CUSTOMER ... but am now BEREFT. App crashes immediately every time I try to open it; from comments here seems to be I'm expected to pay a monthly fee above the original purchase price! WolframAlpha this was disgraceful behavior to not honor your previous implicit commitments, especially to those who supported/took a chance at the beginning... you should be ashamed.

- Crashed after the last update

I’ve been using this app for almost three years, and never had a problem until the last update. After the last update the app won’t even compute simple integrals. The computation times out, and when I try giving it more time the app still won’t compute. After reentering the same thing several times eventually the integral may compute, but sometimes it won’t.

- Not the most ergonomic app.

It needs a better custom keyboard. It’s effectively an advanced calculator app, yet all of the digits are inline. The keyboard should be customized for the use-case. And there is no need for all of the ridiculous special characters. Advanced users who would be using those are probably fine to type out the common LaTeX identifier for those symbols.

- Highly recommended

I’ve used this app since high school they have improved it every year and is a great tool for learning about anything you can think to look up.

- First app that I downloaded on my iPhone 4

This was the first app that I downloaded on my iPhone 4. 8 years later I’m still using it. Can’t say that much about that many developers that quit supporting their apps.

- Unsurpassed utility, broad knowledge base

Wolfram's products have always been top-notch and Alpha is no different. From spline functions to history and even corny science jokes, Alpha covers it all. Inexpensive and always useful, this app actually influenced me to stay with Apple products.

- WolframAlpha

This is a sophisticated yet easy to use app that allows one to find answers and solutions both in summary and by step. Numerical calculations are also available to check your work.

- Nothing Like It

This app is incredibly useful in so many domains. It captures a remarkable fraction of the world’s knowledge in mathematics, as well as the basics of physics, chemistry, etc. And you can ditch your calculator as this can do most anything you can imagine.

- Simply the Best

I took Calc I first semester and relied heavily upon Mathway and Photomath for help, both require monthly subscriptions, but with a $10 iTunes gift card and a $3 App Store purchase, this App not only gave me the answers, but also showed me the steps

- No Longer Working

I have 3 iOS devices and this app. will not run anymore. It opens but then quickly closes when I type in the search box. I have been using this app for a very long time and have come to depend on it. Quit working within the last week. I have recommended it too many people in the past. I also purchased an app for my Windows PC and it is exhibiting the same issues.

- Everyone needs this app!

The instant you add this to your phone, your searches are much more rewarding. It adds a depth of knowledge that you just don’t get with the basic search engine.

- Must have for every phone!

This app provides a lot of value for my phone and for me. As a math major, I could not ask for a better companion to get through college.

- One of the most useful apps… ever!

If you ever use a scientific calculator, this app takes things to a whole new level. I strongly recommend this app for anyone learning, or already practicing, maths and sciences.

- Right on!!

Just had it a few minutes but from what I can see this app is RIGHT ON TARGET and IN LINE with my mind, and spiritual becoming if u will. I’m not sure what is to come but my gut is telling me to move forward!!

- Stinks

I got charged twice for the pro version.. once from the developer app., then from the iTunes Subscription service. Attempting to get a refund from the app developer but after filling out the information the captcha isn’t working. I’ve had to go through several of them.. tried different iterations. Still not working. Very disappointed. Won’t recommend.. ever. I want my $65 back.

- Good but needs scanner for math problems

It’s way to much of a hassle to type in the whole math problem when you could just scan it and be done with it. I thought that’s what the camera function was when I first bought it but I guess not.

- I use it for chemistry

This app goes above and beyond. It shows you solutions AND the work in between. It balances chemical equations and shows you the skeletal structure for chemical compounds. I’m not just finding answers, I’m learning

- Amazing app, 100% worth the cost

I'm a calculus student and this is the most helpful resource I've found. It gives step by step solutions to even the most complex problems.

- Amazing and outstanding

I never thought about an app that could do advanced math like this. It also solves very difficult problems and shows how it did it.

- Fantastic

Imagine everything you want your calculator to do, and this does it and more. But it does much more than math too. Easily the most essential app for any high school or college student.

- Saved me so many times

Honestly the best money I’ve ever spent on an app. When my math teacher fails me, wolfram saves the day with its step by step solutions and it can compute so many types of problems!

- For when I'm too lazy to do math

I did a good chunk of algebra, trig, and calculus in high school, so I have a decent understanding of math, but most of the time I'm just too lazy to do it myself now that it's not required, so I let Wolfram Alpha calculate for X for me.

- I guess

Honestly I expected more from this app because it helps with graphing but it just makes me more confused. Especially when I take a photo and I insert the way i need to solve it, it gives me such a confusing answer. And it doesn’t tell me how to get it either

- What happened to my pro purchase?

I bought the IAP for pro a while back but now I have to pay a subscription for the same thing I already had? Not cool. At the very least grandfather us in. I didn’t need the web version so this change was not needed. Please give us the original features we had before switching the app to a subscription model.

- Best curated data set

This app delivers the most reliable data available and powers platforms executing billions (trillions?) of high frequency trades every year. You can rely on the data set propelling the rise of the 1%.

- Forced pro subscription on users who previously paid

I bought the paid version of this app about 7 years ago which gave you access to most of the current pro features to use only on the app such as step-by-step solutions, and now they just updated the app and removed pro functionality and are forcing you to subscribe.

- Answers all!

Fascinating and useful data for almost anything you can imagine. Type in 140 C and you will get conversions, thermodynamic equations, and opportunities for more exploration. Always a smart and brilliant tool.

- Far more power than I can use

Square root of (3^2+4^2) ⭐️! What is the megaton equivalent explosive power of converting three solars masses to energy via m c-squared? I have no idea, but this app does. Far more power than I can utilize!

- Just buy this app!!!

Best mathematical, scientific program you can have on your iPhone. Get answers to questions that only a super computer can calculate on your iPhone.

- Average data app

This app is worth the three bucks but it has so much potential. I wish the human input analysis was better (like google standard of human understanding). The math and stats are pretty good with specific and detailed results but I just wish that it would understand me better.

- Great resource!

This app is perfect for you if you use google to answer questions throughout the day. For those STEM minded individuals, it is a wealth of information as well. Highly recommend.

- Top of line... But...

This is one of my favorite apps, but the most recent update has caused it to crash on data entry, on my iPad2. Hope this gets fixed soon. I really love this app.

- Codysamson1945

A waste of time and money. In one of the major algorithms I obtained results that were so ridiculous as to be funny if it weren't for the fact that I had shelled out real cash for the privilege of wasting my time with the calculations. I agree with another reviewer that I can find more accurate results much quicker with a generic search engine than I can with this pretentious piece of junk.

- Works amazing!!

This app is a very powerful tool when working on tough algebra and other math. I really like the feature that allows to test your password strength.

- Don't update

Unfortunately, we have seen this playbook before: developer issues update which forces a subscription fee to access features already paid for. Avoid update. Old version works fine. Archive a copy now from your iTunes library and maybe look for alternatives in the App Store that don't "feature" a subscription pricing model.

- A really awesome app!

I have been using this app for more than a decade, and it not only does excellent math, but it knows a ton of facts and answers natural language questions. Really well done.

- Best calculator out there

It really does basically do everything you need in a calculator. Now on iPhone! It’s a real life saver for someone who needs to do real computations real fast.

- Best App Ever

While you do not get the full functionality of Mathematica (programming capability) you get all of the functions without paying through the nose.

- Pictures

I just purchased a yearly subscription a few minutes ago, and I have tried to use a photo of math to find a solution, but every time it just shows filters for the photo. Can someone please tell me how to make it work? I’ve tried making it as clear as possible. If this doesn’t work properly, then I want a refund.

- Had this since 2013

It’s the first app I download whenever I change phone, love it, having it in your pocket makes you smarter

- Awesome

Have been using this app since 2013, and it has done wonders for me. Could not have passed calculus and business statistics without it. 10/10 for sure!

@JenLucPiquant Even though you can't go faster than the speed of light, special relativity makes you go farther than without it. EG 46 years at 1 'g' acceleration with 1/2 up and 1/2 slowing down only gets 560 light years. With relativity you get 18billion ly.

@donmexlar The more times you roll a 100-sided dice the more chances there are of landing on 1. The chance that you'll avoid landing on 1 for a given number of rolls`x` is `0.99^x` For large values of `x` the chance gets *very* small but never quite 0.
