Hatsemtup - Affordable for $truggling $tudents
This is such a great app to use instead of a super expensive graphing calculator. I recommend it every year to my students. It’s fabulous for those on-the-spot study sessions at the coffee shop when you have forgotten your calculator. Many of my students have switched to it as their primary calculator. The functions are the same and the control over graph zooming is a simple pinch method. To identify mínima and máxima you just slide your finger over the graph until the color changes. no left and right bounding required. As an instructor, I use it with my iPad and OneNote during lecture. My lecture notes are projected to the overhead screen as I write them in OneNotes. When I need to demonstrate a concept on the calculator I slip it out by swiping left and a small version of the calculator is overlaid on my notes. When I am done, a swipe right allows me to return to only the notes screen. Students are able to watch my key strokes in real time.
Owndao - Awesome++
I have been looking for a truly powerful calculator for a long time. I've tried variations of the HP top of the line and several were very nice but as I said in one of the other reviews that calculator emulators are great for what they are but the idea is to serve your needs. If a calculator still retains all of the disadvantages of the original then it is not an advancement. This calculator not only provides all the capabilities of the HP that inspired it but also eliminates many of the physical calculator's cons. Ever had a calculator that did everything you needed and more but required a book and a lot of memory work to do any of the sophisticated things? This one does not have that drawback. There is context based help available at the touch of a button. Now you can actually use the full power of the calculator without it becoming a research project. To me, that essentially made the more advanced the calculator the less useful it became. Not so here. I applaud the developer. We don't need exact replicas of calculators, we need something to do a job with the least effort on our part. This is a giant step in that direction.
On top of that, the developer continues to add additional enhancements without resorting to “forever pay”. This is truly a rare gem.
Calculators are not sacred but my time is. Get this. You won't regret it. Now I can get on with my work!
Hungryspider - It just keeps getting better AND .......Most likely It’s all you need and want😃
I have said this before and I am saying it again be because this calculator just keeps getting better. Most likely it’s all you need!
Ohh yess....did I mention the chemistry and Environmental engineering utility! From personal experience this is an ample scientific calculator that can get you through graphing, and bio-statistics,and physics. You will never misplace it, as it is on your tablet and smart phone in a pinch. The programmers care about your user experience, readily offering tips and promptly answering troubleshooting/ how to use the functions. The built help menus are unparalleled. This is one app I won’t be deleting to free up space! Also I think the user interface is extremely intuitive and rich with extras that you simply don’t get with all the handheld calculators that it replaces. Lastly it actually works natively smooth as if it belongs in iOS on your device screen.
BrainyWords - Updated review
I have a new device and an updated calculator. I left a review before but now want to update. I enjoy the developer took the time to fix all the bugs and improved the calculator. Math classes get more complicated and it is always great to know with the growing costs of books, school supplies, travel expenses and all things expensive, I am grateful to know there is an awesome developer that takes the time to improve this wonderful application and send all the loyal product users updates at no additional cost. Other developers and book writers would just add pages to a book, or improvements and label it new edition and charge for a new improvement…or more money for fixing the bugs. Thank you for being such an amazing and devoted developer. I will always look forward to purchasing new items in the future. It is also great to be able to review and refresh my math skills on the newly improved Graphing Calculator. Stay awesome!
KeithSmellBetter1491503 - Great price but a there is a flaw
I am giving this 5 stars because compared to purchasing a ti-84 it is fantastic. A ti-84 is around $120 while this is only $6. We have ti-84s at our school and I prefer those because of the buttons being easier to use and press but they can do much about that because this is a touch screen phone. The one flaw I have found while using this is while zooming in closely to a line on the graph sometimes the line will move or extend a bit while I am zooming in then it will change positions when the zooming stops. I was graphing circles and just messing around with the app when I noticed this. I put y1=-sqrt(64-x^2) and y2=sqrt(64-x^2) and I noticed as I zoomed in to where they should presumably meet along the X axis they were messing up for me. Otherwise amazing app and I believe they actually have more features than a brand new ti-84.
Zippy Parmesian - Thanks from a blind student
I’ve been using this app for 4(?) or possibly even 5 years now. It’s the best app I’ve ever downloaded. I don’t think I would have been able to get through Calc BC without it because I couldn’t see a regular Ti-83 well enough. If I could give it more stars, I would. Most of the time, it’s far better than Desmos. Being legally blind, and having the capabilities to do complex math is a life changer. Only thing that sorta bugs me is the splash screen and app icon because if a teacher is peaking over my shoulder they may believe me to be goofing off (happened a few times) because my original iPad Air takes forever to load it (I’ve been looking at an iPad Pro for the bigger screen but they are way too expensive.
Well anyway, thanks to the developer for literally changing my life. I appreciate it.
Statistics teacher - The best calculator app by far
I require my introductory stats students to have a calculator with built in statistics functions. They typically buy a TI84, which costs around $100. Last semester, a student stumbled across this app and asked if he could use it for his calculator. I investigated and was amazed to find that it perfectly emulates the 84. I haven't found anything yet that the 84 can do that this app can't. Best of all, it costs 1/20 of the 84. What a buy! From a teacher's standpoint, the only drawback is that allowing students to use the app means I have to allow them to use the iPhone during tests - and that opens up a whole new can of worms. Can I trust my students to use only the calculator app and stay off the internet, for instance? There are no easy answers!
Ktscopes - Great calculator!
I love this calculator! I’m a math teacher and have been using it for years. It looks and works just like the old TI-83 so there is no learning curve if you are used to the original. Because of the touch screen to make zooming and tracing easy the graphing is much better than the original and, obviously, much faster. The last update changed the display so that the lines of entries alternate colors, which I don’t happen to care for, but that is just a personal preference. The developer did (does) a fantastic job with this app.
I don’t know how long ago I wrote the above paragraph, but it’s been several years at least. Since they asked, I’ll just say for the record that I’m still using it and I still think it is a great app.
Nowradioguy - Excellent for Statistics!
I teach Statistics at a community college, and our syllabus and textbook require access to a TI-83/-84 Calculator. I've recommended this app to my iOS user students who cannot afford a physical TI. It's got color graphics, something the real TI-83 does not. Plus, it prompts the user right on the command line for the correct arguments needed for a particular Stats function; e.g., for normalcdf, the prompt calls for lower limit, upper limit, mean, standard deviation. Oh, and did I mention the app developer is just an email away and is extremely responsive? You will not regret installing this app on your iPad or iPhone.
It also offers more than one option for conversions between rectangular and polar forms of complex numbers, so essential to AC circuit analysis.
Mic_AR - Wonderful, Powerful, and Free
This app is great!
I’m a student and often use a TI-84 Plus CE which costs 100$ plus. This application seems to have the vast majority or possibly all the same mathematical functionality as my TI calculator and is totally free. In addition the layout and design of the app seems to take some hints from TI and other purpose built graphing calculators. This made it easy for me to use coming from a TI calculator. The app also improves on many of the monotonous annoyances that come with using a conventional calculator. By this I mean things like scrolling through lists, finding intersections on graphs, moving your cursor etc. A lot of these are solved since you can simply touch what you want to interact with as opposed to clicking away with the arrow keys that are featured on most graphing calculators. Finally the app runs much faster than a normal graphing calculator while not requiring an internet connection like Desmos and other free graphing services out there.
Overall it’s a great app and I highly recommend it. If you need a capable phone calculator, I would give this app a shot, It’s free so you don’t really have anything to loose.
A happily surprised student :)
Dana jane b - EXCEPTIONAL!
PERFECTLY DESIGNED AND IMPLEMENTED GRAPHING CALCULATOR!!! Best app ever, best graphing calculator ever -- bar NONE!!!! I cannot believe I have been hauling around my bulky "ti 84 plus c silver edition" (for 2 years) when I could have been using this app. i cannot believe I have taken five junior college math courses (int algebra, trig, precalc algebra, nature of math, finite math) and no one has told me about this app. I cannot believe I have suffered with not being able to easily see/know window mins/maxs and have labelled tick marks while looking at "graph." This app is what the physical ti graphing calculator SHOULD be doing, but cannot, because ti graphing calcs dont have a touchscreen like our smartphone!!!! With this app and the wolframalpha app, I can do anything. (Please make a CAS calculator, too!) I wish i could give the rating of INFINITE stars...
Hutch1919 - Purchased Back In College - Still Awesome Tool frequent updates
While studying statistics in college, I went to the library and forgot my calculator in my dorm room. I was of course working on an assignment that was due soon and couldn’t go back to my room. This app saved the day!
Fast forward to a few years later, I was tutoring someone and they didn’t have a calculator but were familiar with the TI-84’s layout and workflow. This app came in handy when helping them solve some equations.
One of the best $6 I spent in college and I would do it again today because it’s constantly updated and user friendly. Thank you to the developers for a great app!
Iceywhite - Best thing ever made for the iPhone!
I absolutely love this app! Ive had it for years and I still use it every day! I love all the new features! One complaint I do have about the newest update is that the older versions let you simply click your previous calculations and it would copy it right into the place where you are typing ! that saved me so much time especially when they are really long numbers. This new update isn’t letting me do it anymore ? Is there some way to turn it back on? If there is and you are reading this please let me know !
But if not I hope they add that part back in the future update, besides that this is the app MY iPhone was invented for !
It is amazing !
Caylin5200 - i 10/10 recommend this app
I bought this app last year on my phone for algebra because i was having a rough time and rona started so we didn’t have the classroom ones to work with. ever since it has been so helpful and i use it for geometry too. it’s a great app to have and it’s soooo much cheaper than buying an actual calculator like this but still works the same it’s just an app on your phone which also means if for some reason you need to use the calculator for something your going to be most likely to have your phone on you than a big calculator. if your thinking about getting this app DO IT you won’t regret it!
FrankyB103 - Great!!
I cannot say enough about this graph calculator. When I needed one for my graduate statistics course I was bummed thinking what I would have to pay. When I saw this app I just knew it was too good to be true, and would never be like an actual scientific calculator. I was wrong! Not only is it beyond reasonably priced, it is the exact same as any handheld one. I even had my professor check it out and she loved it. Also, when I had some trouble figuring out how to use some options the creator responded to my questions within 24 hours, and explained it in “layman’s” terms that made it easy for me to comprehend. I love this app, it is well worth it.
MaffTeacher - Great!
I haven’t had a chance to evaluate the whole app yet (therefore only 4 stars—sorry!) but it seems to function so much like the ti calculators that if someone needs to switch between this and one of ti‘s graphing calcs, it wouldn’t result in much getting used to at all. That is a HUGE plus. Students can practice with this App and then be better prepared when they are limited to an actual calculator for school or taking the SAT or some other testing purposes. I find it absolutely excellent that students can have access to a calculator like this without having to pay over $100 for an insanely cost prohibitive calculator that is only really worth about $15-$20, if that. After 20 years in math education, I could say so much about that racket but will refrain.
Goreal - Exactly what I need
I teach statistics and I know that not all my students can afford $120+ for a TI calculator. They can use a class set that I keep in my classroom. I recommend GraphNCalc83 to them to use at home for their homework. This app does everything that the TI84 does. Sometimes I even use this instead of the TI84 during lectures.
Also, I think it was wonderful that this app was available for free when the schools were closed during the pandemic. This really helped out my students during online learning. Thank you!!!
Mim197936 - Great for a Stats class
I downloaded this for my Math 103 class and it worked fantastic. Colors, capabilities, zooming in and out, just limitless in my opinion .
Although it was hard having to use an archaic piece of plastic in my proctored exam. I am so surprised that graphing calculators have not changed at all since 1998 and they are still so expensive.
I’m hoping soon the colleges will adopt policies that allow us to use this technology such as this app. You would think that if were being video taped in a proctored exam that we could use this program and not the junky piece of plastic they provide.
Magic0101023 - Fantastic App!
Thank you so much for this, I can imagine how useful this will be for me in the future for my college years! The reason why I bought this is so I am able to help my friends out much more effectively when I am not at home (meaning I don’t have access to a calculator to check). I absolutely love this also because of the button layout and everything is exactly like my TI-84 Plus CE so I am able to use this to its full potential. Please keep this fantastic app running, you (the developer Ernest Brock) are amazing to say the least.
Volleygirl 718 - Love to use in classroom
As a trig/pre-calc teacher I love this app! I use notability on my ipad to project notes (SO much better than writing on the whiteboard) and can easily go back and forth between this and notability to show them graphs, how to enter things into their TI calculators etc. My graphing calculator is very old (I taught years ago then took a break to be home with my kids and recently started teaching again) and this is so much better than carrying it or buying a new one that has color. Thank you for creating this!!
Bulldog158 - Nice functionality
I have been using this for two years. As a Math and Science teacher, I love the versatility and the fact that I always have my phone with me. I use a TI84 regularly and like this app better. The reason for two stars is the last update. I use the conversions tab an awful lot and it has stopped working. I can no longer choose my options. This gets fixed and I’ll definitely be a five star person.
It was as simple as getting in dark mode. Easy fix and all is good!
Hcmath - Excellent graphing calculator
This calculator is both versatile and easy to use. For anyone used to a popular stand alone calculator, this app is an easy transition, as well as being more convenient, since it is always with me. I have used a couple other competing apps, but this is the one I kept. I look forward to using the new math typesetting feature. With every
new version, the calculator gets more powerful, while maintaining its ease of use! Thanks for building this app!
Edw42 - A Really Useful App
I discovered the TI-83 Graphing Calculator a long time ago, and reached for it to do lengthy calculations frequently. When GrafNCalc83 came out I was very excited about it since I could now do the same calculations on my iPhone. But it was missing a convenient way to create Programs - until now. I can’t wait to create some programs that I use frequently. Many thanks to the author for maintaining this App AND for adding all the new features. If you use the TI-83, you’ll love this App, and you can leave your TI at home.
Alex9982 - Excellent
Awesome features and constant updates make this a must buy. The developer is super active, and responds to questions quickly. Many times I just need a graphing calculator and this is the only thing I ever go to. It’s literally a few bucks for more features than an actual graphing calculator. If you need something fast and easy, go with this. You won’t regret it. If you need any help, there’s instructions for each function and if that fails, the developer is fast to respond. Awesome app!
UNDERGROUNDSURROUNDSOUND - GENIUS!!!
I was faced with a statistics class that required a TI-83 plus calc, and was having a hard time ponying up the money for one. I found this app and it saved me in my moment of despair! It performs exactly the same as a physical TI-83 in every way and I couldn't be more pleased! The creator is BRILLIANT and a life saver! The free updates show his attention to detail and passion for making this app work for his customers again and again! Truly the BEST productivity/calc app in existence! THANK YOU SO MUCH! 5+ STARS!!! :)
WafflesWill - Better than a graphing calculator
This app is better than a graphing calculator due to the touchscreen capabilities. It is also much cheaper than a brand new TI-84 ($6 vs $120). As a HS math teacher, I allow my students to use their cell phones on many assignments. I recommend this app (and DESMOS) to any student that plans on using their cell phone to analyze math in and out of the classroom. I also love it since now I do not have to carry around a graphing calculator since I always have my cell phone with me when I teach and tutor.
TomRob62 - This app helps me get through college
I got this app when I was in high school because my family shares a graphing calculator, but now that I am in college, this app has become instrumental in helping with homework. There are a lot of functions that this app has that most graphing calculator lack, such as the molar mass calculator or a built in periodic table. Those functions are major time saver and a great way to double check your work. It is very useful.
Passitalongsomore - Super good app
You might not be allowed to use this app on a test, but it is as functional as any standard graphing calculator out there. The developer has done a good job implementing all the features and even enhancing the experience with the phone touchscreen. It is not buggy or slow, and the design is well thought out. There is no drawback to this app. I wouldn’t go back to a real graphing calculator, though a graphing calculator has real buttons. I use this app all the time. For me it is worth the investment.
Carlperez54 - Math Prof says : SUPERB TI-8x emulator for iPad and iPhone
I am a longtime math teacher who loves this app. As other reviewers have said, it is better...much better...than any of the TI-8x models on which it is based. Easier to use..better display...better graphing...better! Texas Instruments keeps trying to get us to upgrade to more expen$ive calculators with increasingly needless and unuseful "features". Why? This app turns your iPad/iPhone into a super-TI-8x calculator...at about 7% of the price! If you like and use the TI-83/84 models, this app is highly recommended.
X4130 - Like a TI-83+, only better
Bought this on a whim while taking a Stats class to compliment my ancient TI-83+, and am blown away by it. As other reviews have stated, perfect port of the 83, with vast improvement made to UI and function explanations. Worth every penny and more, could not be happier. Years later, still my go-to calculator app. Lives on my Home Screen.
Even better, the developer continues to update an already bug-free an excellent product- awesome!
NM1D538 - Great customer service. Awesome application.
This app's developer is the best. I had a question after I purchased and he was on it in less than 2 hrs. He even comes out with improvements on occasion for free. It's awesome.
This calculator is better than my ti84, and at a fraction of the cost you're getting it for a steal. If you have any need for an actual calculator unlike the bull one that comes with your phone; get this one.
TL;DR This app is the best purchased app I've ever come across. A true hidden gem.
Kitty🐯🐱🐆🐈🐅😸 - One thing
Very easy to navigate I love using this for class, but when I have to calculate z and t scores sometimes it doesn’t refresh from the last when I press enter and I don’t catch it right away, you have to toggle to the data option to refresh it sometimes and I wish it would auto update when you enter data so there isn’t a risk off getting inaccurate scores from zs and ts exc that aren’t updated right away when you enter data
Dave260059 - Outstanding graphing calculator
Purchased this app vice an actual graphing calculator for my calculus class. Had zero issues with the application, the handouts provided to show button functionality/equation input on a TI-83 matched exactly to what the app has. I would argue the developer went above and beyond in being able to add additional functionality. The developer has great support and provides free updates which is reassuring to see the app being supported.
MarichatShipper55 - So helpful
Using this is so great. It has all the functions of a regular graphing calculator. It’s really great because instead of paying 100 dollars for a good calculator, you can simply download an app! Of course I do suggest having a calculator if it’s in your abilities, as there are moments where you are unable to use your phone, but this is a really great alternative if your at a financial loss, and has the same functions.
Yastin3 - Worth the value
I bought this app for my Precalculus class as I needed a graphing calculator and it’s so helpful. My friends spent around a 100$ on their graphing calculators and I spent way less than that on this app. This app had everything that I needed a graphing calculator for when I was in Precalculus and Calculus. 100% recommend the app for those who don’t want to splurge on a buying a physical graphing calculator and need something cheaper.
Bussyome - Love this app for teaching students remotely!
I haven't found anything even close to as thorough and well designed this calculator is! I find that there have been several times that I have actually learned a few things myself from the information portion of the app. It is as close as it gets to the real hardware and even better because it prompts you for input. Bravo!
Treesdanceinthebreeze - Loved
I have had this app since 2014. I bought it because the stats class I was in needed a specific function on a graphing calculator but I didn’t want to buy a brand new calculator. This has been my go-to calculator since. The only issue I have and it’s more pet peeve than anything, is that when you calculate a number and it won’t be a whole number the answer comes out as a fraction and then you have to punch in a few numbers to get a decimal. It’s annoying but other than that the calculator works just like a normal one for less money.
Andy Borne - Really good
Okay, it has arrived. A very decent TI-83 clone for the iOS. Looks to be very close to key-for-key to the actual hand held device. Many thoughtful enhancements to the UI, particularly in graphing. Everything I expect to be there in Stats looks to be there. I was particularly happy to see this app play nicely with other apps, like my drawing app, for multitasking. I can show, draw, calculate, all at once and that is so nice. Whoever wrote this app: A+.
Bg002h - Love the new version
Everything I already loved plus beautifully formatted for the iPhone X and larger screens. This has been a solid product for years… ...best calculator app for what, like 7 years or more? Looks great on iPhone 13 pro Max screen now too! Makes me miss my TI-82…very familiar interface.
I’ve loved this app for years…all with free updates. I love the programmability of this calculator…super handy and robust!
Slow Grey - Awesome Calc
This app works great it’s just like my mechanical TI 84. It’s great for subjects like algebra, calculus, trigonometry, physics, and chemistry. I do have an issue that the statistics formulas don’t have the “fill in the blank” type entry screen like my mechanical calculator. I’m not always sure what I’m supposed to enter between the parentheses. That said this app has been great to me. I think it’s well worth whatever nominal price they’re asking.
AK Heli - Spectacular app with great help.
Using this for Intermediate Algebra. Makes graphing and computing such a snap, and does it in style. I have had to ask for a bit of help here and there from the developer to input certain things and the return replies were quick and detailed, often with a pic or two. Quite helpful for me to get back to work. And this is all before the new expanded version. Like it wasn’t magnificent before...
Livelovesmile - Excellent, i never use the iPhone calculator anymore
Ever since a professor asked us to use this for her class I haven’t used any other calculator (app or real world.) can perform so many functions and so easy to use. I don’t even use the calculator that comes preinstalled on iPhones anymore because I prefer this one and find it more user friendly even for basic equations
Vgreff - TI-84 on steroids !
I had this calculator for a few years now and it keeps getting better. It’s fully compatible with the Ti-84 and then some.
The touch screen makes graphing function a breeze.
The natural keyboard is a very smart idea too and appreacited feature. The developer is super nice and very responsive. I reported a bug years back and he fixed very fast.
Highly recommend it.
Mathamie - Accessible graphing calculator as close as your phone
Super easy to use, the functionality of this app is hard to beat. Downloaded it when I was traveling and realized I’d left home without my TI84. This calculator not only saved the day but has since been my favorite go-to. Affordability that levels the playing field too. Thank you!
Shippster - Great for Physics class
I’m a physics teacher and use this as my phone app because it works just like the TI calculators. The touch zoom and point finding is sooo much better on this app than on the TI or Casio graphing calculators. When I or my students use the built in calculator we often make mistakes, but not on this one. Free updates have been great. Thanks for actively maintaining this app!!
Yoders.6 - So shines a good deed in a weary world.
I will admit, I only downloaded this app because I wanted to commend the developer for making the app free to download for students without access to school-issued calculators, due to the pandemic. He didn’t have to do this, but his generosity is nevertheless appreciated. The app itself is pretty cool, too; I especially love that I don’t have to dig out my TI-83 or my SilverLink cable whenever I want to write up a quick program.
Trump Virus - Using more than 1 letter to name variables
I used to make program/games with my old TI 86 calc. One of the cool things it did was give you the ability to name variables instead of just a single letter. This comes in handy so you can label your variables and give it a name based on what it represents. Also, this will also prevent interference due to multiple programs sharing the same single letter variables. I think it would be helpful to include this feature in your next update.
Elijahwigi - Saved My Life
Due to online school, I still had my graphing calculator at school. I looked for other apps because I was not going to drop $100 at the moment. I used apps like “taculator” and they worked, but I had to spend $4 per month. This app literally saved my life. It does all the functions without the “PRO” feature (where you have to spend an IAP). I could not be more thankful for this app.😎😎
Msteright - This calculator is the BEST!
This calculator is almost an exact replica of the TI-83 but with color graphs and touchscreen for finding zeros and intersections. He keeps finding small things to add and fix but it works just like the old calculator. You can write programs on it, use the color periodic table, finance solvers, geometry solvers, graphing almost any equation. I love it and don’t need to use anything else. I love doing statistics and predicting with regressions. This thing is so helpful!!!
Dbdheielwkaoabdbs - Best Option Out There
This app has saved me hundreds of dollars and hundreds of headaches. It’s pretty much impossible to do any calculations when I’m trying to re-teach Geometry, Alg. 1 or Alg. 2 without a TI graphing calculator. This app has made it possible for me to do my job all without having the tools to do so readily available to me.
The only thing is I’m finding things out on my own little by little in terms of functions, graphing, and matrices. Other than that the app is spot on.

PX.review - such a great calculator - perfect for TI fans
If you're after a TI calculator for your iPhone this one is for you. I use it all the time, and the developer always responds to feedback and questions. Grew up using a TI-85 and it's the perfect pocket replacement. It's worth every cent - I guarantee you won't regret buying it. 😄
TheNicknameFrankIsAlreadyTaken - Fantastic
I’ve been looking to buy a calculator for graduate studies, but this ticks all the boxes and works brilliantly! The updated version continues to improve on an already great product.
Updating my review in light of the recent update: fantastic as ever!
Dammy333 - Awesome App
Best calc app I have tried. Better than using my physical Ti83. Works really well with iPad split screen function.
Derpioid - excellent
if you have muscle-memory for using this particular calculator style, you’ll appreciate the care that’s been taken in developing this app
the additional functionality fills in many of the ‘gaps’ that were previously difficult or laborious to do or visualize on this sort of calculator
MalikAustralia - Mal
Don’t want to say much except: “Its awesome.”
Buy it and try it - Better than the original device
Compared to the actual calculator being emulated it is much faster, easier to use and has many additional features and capabilities. This has to be one of the best calculators on the app store.
It is easy to use and the built in manual and help is excellent. I especially like the programability and the built in apps to solve finance, chemistry and geometry problems. This is excellent value and makes carrying a physical graphing calculator unnecessary, - highly recommended.

Lwiz - Nicely done.
I use this author's rock solid financial calculators almost every day. This 83 seems to be just as dependable. Includes lots of extras, super fast graphics and accurate calculation. His calculators including this one are well designed and implemented and are a pleasure to use. What more can I say!!
John the Ipad user - Great Calculator.
I really like this calculator; easy to use and intuitive for every day mathematical problems.
Similar to large computer programs, it requires a learning curve to become familiar with the operation of specific applications, but it is well worth the effort.
The on-board information for individual keys is helpful, but a user manual with examples and an alphabetical index in PDF format would be a welcome addition.
GreenGoblin69 - Best graphing app
This is just as good as a real graphing calculator and I use it to do homework in my calculus classes
Photon Dreams - Best calculator for ios
Well made, well supported, well documented. What more could you ask for?
RealmOfChaos - Great App
D2L man - Gets me fired up for math class
Graph n calc changed my life it was like AA for me it truly brings out the best in you. Changes the way you truly look at math and life, so much love for the creator and D2L for helping me find my way through addiction, abuse and sexual intercourse
Giggleplex1 - UI a bit too big
It’s a great calculator, but I find that the UI is too big in portrait full screen and too small when it’s used in a slideover window.
