Very useful. Great tool

Missing some content. The GPIO section diagrams all look the same regardless of which operation mode you’re looking at. Microcontrollers should really have an STM32 section. Other than that a useful tool. Would be helpful to have frequency as an option for spectrum instead of nanometers.

Kirchhoff’s laws?. I love it. It’s a great tool for the money. I would like to see node analysis and Kirchhoff’s laws added.

Dumb. Dumb

The best app ever for ECE. This is one of the best apps out there. Period So smooth and easy to use. Highly recommend upgrading to the pro if you use and need more tools and features. It’s a great deal

Great app. I am a electricity teacher at a technical collage in central Florida and i use this app every day I also recommend it to all my students

ok. its good for what i need it for

Too good to be true 👎🏿. Says free app but once inside be prepared to pay for what you probably thought was gonna be free 👎🏿

One of the best apps. I've had an iPhone for years and have never spent money on an app, but I couldn't go without this one. One of the best apps I've ever come across and is a must-have for anyone involved in any type of engineering, at any level.

Very crucial and informative. Would recommend to anyone.

Must have. Must have for electrical engineers, or electricians! Five stars.

Please add schematic symbol descriptions. Very nice app.

Everything you cannot do in your head is locked behind a paywall. Nothing I cannot do in my head available without upgrading. Not worth the money to upgrade.

Amazing is not saying enough! This is the most remarkable app that Ihave wver used.. Thank you so much for the most incredible app that I have ever used! It continues to be extremely useful in every aspect of electronics that I have encountered.

Amazing and complete for enthusiasts to all level. First of all, is a Genial work, from presentations to contents, really a master piece collection for enthusiasts until pro level, very intuitive, great examples and projects. The Pro version worth each cents!!!

A couple things before I hand over $7.99. This looks like it has potential, but I see a few issues. 1) On an iPhone XS screen, the brown resistor band appears as dark red. I deal with color every day, and my phone display is fine. Perhaps find a more neutral brown color to use. 2) Browsing through the free features, I managed to activate a musical note in the function generator that sent my speaker into a high pitch. I could not stop it. Muting the volume did not work, and I had to press the power button. Hope to see more, as I’m just starting into electronics.

Nice. Thx 🙃

Just remarkable!. As an electrical engineering student, this app has far more than I could have ever hoped. The free version is okay, but the app truly shines once you unlock the other features. I especially like the function generator, 555 timers, and logic gates. You can tell a lot of time and effort have been put into this.

Garbage. Another locked behind paywall software that wont help a novice build their own circuit. Instead its all comprehensive to what these narcissistic electrical engineers think

So Much. There is a lot of function with this app wow. Thank you for creating it!

I love it!. Best app on my phone!

Ok. 20

Don’t buy this app. This app doesn’t have all the documents available in it the pdf are empty and most of them and the apple also refuses to refund.

The best electronic app I have found. Great app and updates have been frequent and big improvements. New ver. is really worth the upgrade for those that have not yet upgraded!

Easy to use... Whether your a student or an EE, this simple program delivers quick and easy calculation. Basically, it is a time saver. It is good to find such an app for a change that delivers upon its promise. For $7.99 upgrade it is well worth the expense. No more sitting down drawing out and using a calculator, loading up a major EDA program to do simple calculations, this program fit comfortable in the center of those two extremes.

Great App! 💡. I only use a small portion of the toolkit, but it fits my needs exactly!

Great app!!. A must have for any electronic enthusiast! Not to mention how great it looks. Nice graphics

Great tool. This is the best tool I have found yet. It contains all things things that I use to have several apps for. It is defiantly my go to tool for electronic design.

App. Great app

3/4 of its functions in the free version are locked.. 3/4 of the functions in the free version are locked. I understand that a free app will have to have some features disabled, but 3/4 of them? There needs to be more enabled functions on the free version. Deleted the app within five minutes of downloading. You can do better than that. P.S. >:(

Muhana876. Thank

A Very Helpful Tool. A very handy tool for controls engineering and field work. I use it almost every day. Definitely worth the little bit I paid for it. E-Bob

Great app. Awesome app.

Fantastic app. Whether you are a seasoned EE or just someone new to electronics this is an invaluable tool. Thank you!

Indispensable Companion. EE Toolkit is the reason I own an iPad. This app is the best tool next to a DVM! Everything one needs to know or forgot from school is right at one’s fingertips speeding up any electronic endeavor. This is a must have application for any creative individual in the field of electronics.

Great basics. Learning quickly and very efficient

Buy It. This app is regularly updated and cared for, and it is an invaluable resource. Just buy it already. Jeez.

Worst ever. I would say it is not the best but not the worst. I say this because it says upgrade to premium and you will get this and that. But a plus is that they say spend 7.99 some dollars. Like why though it is literally useless.😬🤮🤢🥱😿😾

Genuinely Useful. This is a well thought out and genuinely useful piece of software that ends up saving me hours on every project. It is worth the extra money for the pro version, as you will see if you try the free version. The documentation portal aspect alone is a helpful tool (how many times have you had to search for your GPIO wiring diagrams because you forgot which pin is 5V and which is 3.3V) and add on top all the remaining aspects and it’s well worth it.

Must have!. I had the free version for a whole ten minutes. This app is absolutely incredible and never ceases to amaze. I’d buy it twice just to support the developers

Almost amazing. This app looks like exactly what I’m looking for. Seems pretty easy to use, has the formulas, etc. I find myself wishing there were more circuits included though. I’m an EE student and working with op amps right now. There’s a bunch of fairly standard circuits included, which may be everything most people would need for working in the field. However, I’m running into circuits not included - such as an Multiple-Feedback Bandpass (MFB) active filter. I appreciate what they have here; I would just recommend looking to see if it has everything you need (or that you’re okay looking up what isn’t here yourself) before buying it.

Unparalleled. Complete and centralized source for all things electronic. From basic DC operations to advanced data sheet references, this app has it all. Continually improving and a must have for anyone even remotely interested in the field. Great source of information and references!

Sure wish this existed 10 years ago!!!. I ran an engineering lab until 2013...had cheat sheets all over my cubicle and to Texas Inst calculators!!!!! Thanks

This App Rules-Glad to pay for full version. This app is incredible. I graduated in mechanical engineering, and found that although I had been exposed to some circuit basics, I didn’t know where to start when working on my own electronic projects at home. This app has done wonders in improving my understanding and ability to build an intuition for what is going on. Well Worth the price for the full version!! Thank you -

Not useful. Basically everything useful is locked. Mosfets are locked, Arduino®️locked, and the only way to unlock is to pay for the pro version, and you can just search how to use the things that are mentioned above in Google. So this app is useless.

Nice. This is a great app and has a lot of great features! Issues with voltage divider (loaded) . Looks like Rload and Vin are swapped.

Nice to add.. Yes it’s updates making the app goes so far as preferred, but in the field of Rectifiers:- there is no center tap Rectifying, it would be also good to add it. thanks for a great app.

Not many options, unless you spend $7.99. Being a developer myself, I don’t see this app as a good value. This should include a few more options before you have to pay. It should at least be somewhat useful. The 30% / 70% should be implemented. I hope the developer takes my comment and updates the app. I feel many more users will download after making some small changes.

Love this app!. Brilliant go-to source!

Essau. Very powerful tool

Nice. Quite a good app!

Five star all the way. Really good tool set, especially for noobs.

Excellent app. This app has many tools to help you in electronics. It’s been a real time saver and a very valuable tool for me. The app is constantly updated with new tools and improvements by the app developer which gives me more confidence in the app.

An invaluable resource. Can't live without it

Good app. Useful for engineers

I love this app. It's easy to navigate, easy to understand, it's got everything it's awesome

App. Great little app

Don't waste your data or money. What a joke, most of its locked and costs to unlock. Don't bother with this rubbish

Great app. Really helpful for beginners or a quick reminder for the pro's

Fantastic App. I find this app to be intuitive and helpful thank you

Neat little tool. This is a nice utility for someone who needs a few hints as they grow into electronics as a hobby ... like me. Clear, concise, accurate, intuitive. And excellent value!

Best App. One of the best apps I have for doing electronics, has all the modules I need.

Brilliant!. Google just lost 10% of my searches because of this app!

Awesome App. This version is fantastic , if you are an amateur hobbyist like me you will love it , everything I need in one place. Thanks

Great!. Great for starting out!

Good. Meets the needs on engineers.

Very useful. Very helpful app

Bribe. Writing this to get the free content. Nothing in this app that can't be googled still nice to have a concise guide.

Great App. I'm a novice to electronics but this App has helped me to get started. Definitely recommended.

Great app. Easy to use, I intend to add more tools, great work. Thank you

Great apps for Engineers. Keep the great work. Thanks for the free great apps for science and Engineering.

Great app. Good app. Lots of great info very helpful.

Great app. Great little app for both the amateur and professional alike. Would recommend.

Very handy tool. What a Great app!!! Please keep updating and adding! Makes my life so much easier!!

Dr. Elegant clean design, coupled with all that the hobbyist would ever need, and then some.

Good app. Good little app for simple circuits.

Very informative for noobs like me. This app has helped me understand more about circuits, thank you!

Great App. Great app!

Very good Reference. This app is a great idea for those who are new to electronics and as a quick interactive guide/reference to save time and effort when experimenting.

Great app. Great app

Useful!. Awesome and useful

Works well.. Using it to help teach my daughter some basics and application. Found myself use it to quickly sum up some total resistance.

All basic things are locked.. What's the point in getting a free app if you have to pay $10 to do anything with it

Very good app. I like this app, but I think that there should be more free things.

Awesome reference. Awesome reference

Reviewing. Good

Lots of great stuff. Really like all the added tools!

Great App. Thanks for assembling this information in an accessible format.

Nice interface !!. lot of compenant and nice interface !

EE manufacturing. Tools kit is easy to look on , reference is perfect to me. I recommend to Student and professional . Jerry

Free. Free = 5 stars

Truly usefull. I use it all the time! Never forget those forgettable items.

So many features. This app is indispensable

Great utilities. All functions as promised

Good. Good

Awesome. Great app

Nice app. Very useful!

Complete. Quite a repost app once all features are unlocked with many handy tools especially for amateurs like me

Tech. Great when you are stuck

Necessary for any maker!. Like a microwave; you never knew you needed one till you had one. This app!

Alright. It's pretty good

Great app. Very useful and handy when trying to refresh your memory

Super. It's super gooododododod

Ifucf. Igufuf

Burda. Awesome app

Electronic Engineer Toolkit. A must have app

Great app. Really great app for electronics.

So far so good!. Excellent time saver when it comes to substituting component values in a circuit & see the effect it has on the voltage/current changes in the rest of the circuit.

Great app. This app is both useful and entertaining, great for the hobbyists and pros!

For what it is. This is a very solid app that is an easy way to ensure the devices your using are correct, it is what it is and does it well

It is pretty useful!!. It does comes in handy most of the time!!

Very good.. Might consider buying pro version.

The best. By far the best, most useful electronics app out there. Very informative. Even for someone with not a lot of electronics training or experience (like me). Thanks very much to the developer for his hard work.

Where is the 6th star?. Love the app. Lot of documentation and examples.

First use. Just started to use this app but looks like it'll be helpful for sure.

New EE Toolkit Rocks!!!. This app just gets better and better. Only a few years ago you would have needed a dusty pile of reference tomes or a super expensive scientific calculator to do what EE Toolkit puts in your pocket. Nice ;)

Didn’t get the paid version. I didn’t get the paid version and all the function are locked. Thanks for nothing.

Wow. Vraiment très complète comme application. C’est du sérieux. Beaux et très détaillés, avec symboles, formules et tous les petits extras. J’ai acheté. Un gros pouce vers le haut. J’adore. Quel travail!

Pratique.... Very good app....

App is dishonest. App bribes users into leaving 5-star ratings by promising to unlock 7 more tools. Reviews can't be trusted.

Très bonne application. C'est une excellente application et très pratique!

Good. Very useful.

Very nice. Has many great features, makes it so much easier to do all the calculations

No stars earned for poor communication skills presented at this time. Improve hospitality less friction in communication.

Useful app. This app is very helpful to use

Great tool!. One tool I've been using regularly is the dB cross calculator. It seems I'm always going back and forth between different units and this is the most complete tool I've found - even those on the web. Add in all the other tools, for fun and work, and I find this a very useful app - well worth the price.

Works for me!. This app is what I have been looking for for my electrical circuit projects. It has tools for calculating and selecting electrical components for all kinds of electrical circuits. Works well for me with my hobby projects.

Great for beginners. Great to get started if you need a reference from other material that your learning. Not the all in one engineering app but has potential for a solid foundation

Nice beginner app for basic formulas. The free version is worth trying, it just offers fairly basic electronics items like serial resistors, ohms law and such. Not bad thought as it does the calls for you. It also has many locked features that look very good and appear to be worth the payable upgrade at $6.99. Will be trying the upgrade soon

Great Tool. I am new to electronic circuit design and this tool is giving me a great foundation on which to build. Although I'm only a hobbyist I'm really looking forward to everything that it has to offer.

Great on the go tool. I've been using this app for product development for all the times I don't want to calculate a large transfer function ...... This makes it so easy !

Students and new engineers need this. In a tough job market, you need to be correct and swift. Having all the tools helps you do it.

Great Review App. Has all the electronic calculations in a nice arrangement. Getting ready to get back in the job search market and needed something to review all the formulas I haven't used in years. This was the perfect answer!

Pretty useful app. This app is pretty good for a lot of basic things. I've only used it for about 2 weeks this far and everything seemed to be on point. I would like to use it longer before I give a 5star review. I would definitely recommend this app.

Not Recommended. I came across this app when looking for a mobile way to design schematics. This app sadly doesn't let you do that (or at least from what I can tell), but it still looked promising. This lead me to download it. Initially I was actually quite amazed at what it had to offer, and I clicked on the various features to try them out. This is where I began to get disappointed. Basically everything in the app is "locked", which means you have to pay to use it. This is where my frustration occurs. The only feature which I can honestly say I still use is the 7400 series logic feature. Everything else is either plain garbage or has to be purchased. So is it worth getting? Maybe. I don't think its worth it, due to the fact that very little features are available for free, but it MIGHT be useful if you pay for everything. Its hard to say. I DO agree with the fact that not everything can be free, and the fact that the developers need to be rewarded for their efforts. However, I feel like the app provides so LITTLE features that it is almost impossible to want to take the chance to buy the PRO version, since the free version has so much to hate. Its just so frustrating that you almost immediately want to just get it out of your view.

R&D Engineer. This is very handy tools for everyday used I like this one and great to used for research and study. I would rate this topic for learning guide and I would like to recommend this site.

If you like it BUY THE PRO VERSION not the upgrade. First: This is an EXCELLENT set of tools. I have a BS in Electrical Engineering, General Radio Telephone FCC license with Radar Endorsement, Amateur Extra FCC License, RF test and measurement equipment, etc. This Thomas Gruber did a masterful job putting these tools together. My only problem was buying the upgrade, unlocking features instead of just buying the Pro Version. The "Restore" locked to unlocked just did not work on my new iPad. Thanks to Thomas for his suggestions, but none of them helped. I've seen this on other apps so my guess is that it is just an undocumented "feature" of the way the App Store works. No problem. I just followed my own advice, purchased the Pro version, and now it is installed and works fine. Buy this APP or better Toolbox of Apps. It's one of the best Apps on my iPhone and iPad. I also have the HP-41C App and these two are the best Engineering support Apps I have. Revised July 31, 2017

Great app - Helped me learn. I was really new to electronics and circuits--still am! But this app has helped me learn and become more proficient in the subject and I am really glad that I downloaded it.

Fully loaded electronics app!. Well organized, fully loaded electronics app. Everything you might be looking for in your electronics projects, all in one easy to use app!

Handy. The tools are very handy and convenient as most implied and that is the expectation to some degree but for the novice user it puts professional information at one's fingertips.

Very Useful. I work in the oilfield, which on occasion sends me to locations that don't have cell reception/wifi. This app is incredibly useful. I especially like the connector pin outs and amperage ratings. The layout is perfect and I approve of the thumbnail style display.

My Electronic Reference. I have been using this app a few weeks for communications electronics. Great to have all the calculations that I need in one place.

Awesome tool!. Great go-to app for those that want something quick, simple, and easy to use. I don't use this stuff all the time so when I need it, this is a great reference!

Great package of EE Apps. I needed a function generator and purchased the Pro version. Hard to believe you get that much performance and options on a program that runs on your phone or pad. Highly recommend this series of Apps. Money well spent!

Great tool when you are in the field. It is the dictionary for the electrical world. Reminds you of key facts that you always seem to need.

Easy and fast tool. It's so easy and fast to use it and get the right answer to an electronic question. Thank you

So many tools!!. As a programmer and engineer I am finding new helpful features in this app every day. I don't pay for many things in this world of free phone apps but it only took 1 day for me to say "I gotta buy the full version!"

One of my most-used apps. Use this all the time. The info button that explains what each calculator actually is is a nice touch. However it does seem to still be missing pcb trace copper weights on the PCB Trace Width section.

Convenient. Great app for having some commonly referenced tools and calculators handy. A bit pricey for info that can be found with a quick Google search but here it is all in one place.

App does it all. If you are serious about electronics and the engineering break down, this is the app for you. A one stop shop that is well worth the money.

Looks good on the surface.. Okay , I’d say it has room to grow . I was impressed by all the basics you have in there - RLC, 555 timers ,led circuits . I was not so moved by 2 input gates and the lack of 7400 chips .I tried to look up a 74ls47 IC . It didn’t exist . Also , I can not menu back to the main page . It could be useful as an electronics training aid for youngsters . Not to useful for serious electronics design .

Always There - Convenient. Waiting for wife for "5 minutes", I can do something useful - learn/design.

Handy tool for the EE. I use it quite frequently for quick calculations of parallel resistors, RC time constants and the like when I'm at the lab bench and don't want to go back to my desk and computer.

A great reference tool. This is the one tool i go to while in school. It's easy to navigate and understand. The pro is a bit expensive to me but if you use it a lot, it could be useful.

Exceptional. Perfect for today's world. Super handy when you're on the job and need a quick reference to refresh your memory!

Great tool. It is a great tools with formulas that allows you to developing and understanding the concept of the electricity. Highly recommended for those people who are interesting to become an electrical engineer.

Great app for electrical hobbies!. When I downloaded this app I thought I would use it a handful of times and it would be pretty useful, but I was wrong. I've used it more than I'd like to admit, a true life saver!

Convenient. Nice to have a single location to access so much useful electronic equations and data for quick answers.

Great App for refreshing your memory!. I love this App. I had a job interview coming up and I knew I was going to have to take a Electronics test which I was so worried about. I downloaded this and it really helped refreshed my memory from all the stuff I forgot from school. Needless to say I passed the test and got the job all thanks to this App!!!!

It's always at my fingertips. Nothing here that can't be found elsewhere, but the value is in having it all in one place. I don't often have the need for most of the information, and I can't remember everything from project to project. This makes it easy to brush up on theory and to have the ability to run the numbers without getting a migraine.

5 stars all the way!. I see some lower ratings but for the average person and/or student this is the most valuable app to own. The features are off the charts, while EE with advanced degrees and NASA scientist may not get much use out of this I can assure you it’s perfect for everyone else. Well done Tom!!!

Wish I would've found this sooner!. I already downloaded and purchased less featured apps that cluttered my phone. I now have only a select few apps. I'm happy to say this is my go to source for my EE tools and reference material. I do wish there were page dots on the menu pages. 3.99 for the full version is a great deal too.

Could be what I need. I gave it 5 stars to unlock more tools but have not really had a chance to thoroughly investigate this app. I will update my rating once I have.

Great little reference!. Thank you for pulling this together in a neat app. I find myself opening the app almost daily. It's worth the few bucks it cost just to have the material in one place.

Great Resource. I have been trying to get my son started with what he has been talking about doing for a while. I found the Raspberry Pi and needed a perfect reference source for his projects. Wish I had this when I went through my college avionics courses. It's easy to ask him questions and point to this program for the answers.

Useful. Pretty useful set of tools. I use it quite frequently and having shortcuts on hand makes things much easier

Great program. I am a novice and love the ideas that electronic let one have. I have learned so much from this app program that I used what I have learned to build two projects that worked, Like magic my son said.

Great content and organization but.... The pro version is a bit pricey ... I feel like the app is just a convenience wen you can find everything you need to know in a text book or on the internet... That being said it is a super useful app that saves a lot of time that would be spent flipping through pages to check if you are remembering something correctly. But i think the price is a bit steep for nothing that you don't have access to already.

Awesome. Never thought I'd find a free schematic application for a mobile device this good. It's really impressive and easy to use. I highly recommend!

Great App. Very good app I use it almost daly. Haven't run across any problems with it yet. I am an aircraft maintenance tech and on these computer driven aircraft these days this app come in very handy.

Essential. As an Electrical Engineering student this app is imperative to have. I have been searching something to aid me in my studies and projects then stumbled upon this tool kit. The name fits perfect, it's an essential tool kit needed in the electronics and engineering field. I highly recommend this app.

What I needed. The convenience factor of having so much easily accessed in one place is the big advantage for my position, where I am constantly jumping around in a broad range of spec detailing.

Unbelievable. This app is just awesome! You can see the hard work put into this app so the user can take full advantage of the info provided.

It's there.... This app is amazing. Just about anything you need is there. I wish I had found it much earlier!

Very useful!. I like having all these tools at hand. Saves having to use my browser to find these calculators.
