Great Reference for EEs. Great quick reference app, I use it regularly. Only recommendation for the developer is to add the ability to edit current pages or add my own pages for formulas.

must have electronics reference. Really very cool EE reference. nice graphics, lot’s of useful examples, well done. For everyone who is really into electronics.

Great app but only one problem.. this is a fatansitc app and is very useful, but in the 555 timer section you can only imput small values for capacitors, i.e. smaller than microfarads. In other words, you cannot enter a 4700 microfarad capacitor in the simulator. also there are no dual timers; that would be a nice addition. Otherwise, it is a great app very useful. one of two apps that i use regularly for my projects.

AWESOME tool. AWESOME tool. this App is extremely fast and stable, developer is very responsive, updates come in at a regular basis

Great App. Best quick reference guide I’ve found for electronics theory and calculations.

Rural dude - Problem solved. Previous review mentioned the EE Toolkit did not show up in settings. I changed my password and now it does show up in settings. I don't see the connection but I'm not going to argue with success.

Very useful for me as an EE. It has paid for itself many times over.

Can’t do without it. This app keeps getting better and better with every update. It has just about everything you would ever need for electrical engineering calculations and programming. This is the one app I use all the time.

Well Thought Out App. Honestly, this app will show you and explain in detail how to solve or understand pretty much everything in electrical. I would recommend a background of electrical for understanding, since this is mostly for reference, and not to teach new concepts.

A ton of information for the money. Just loads upon loads of helpful stuff in here. Some of the tools are interactive, you can see in real time what changing the value of a resistor will do do an LED in a 555 timer circuit. Just awesome, nice work!!!

Don’t Buy. This is not a circuit builder

Awesome and Informative app. I’m getting back into my electronics. I’m finding this app to be very informative and helpful. One of the things that has impressed me is that the app designer has added information on various electronic products such as the Raspberry Pi and Arduino. What makes this so impressive is that he as added every bit of information about the product you could want. And it he does the same thing for both the electronic components and circuits. This app is bring me back to my school days when I was learning all this. Awesome app.

🚨🚨🚨🚨. Thanks for the update 👍🏼👍🏼

Superb!!. Amazing electronics tools!! Very usefull!!! Great apps to make my work more convinient!! It really worth for 3.99USD!! Recommend to every electronics engineers!!! Excellent apps as well! Very convinient and quick calcaltaion!!

Awesome app. Super useful ap. I loved to use it often, though, l’m currently having crashes on the splash screen upon initial startup 100% of the time. Troubleshooting

Excellent group of tools!. One question : There appears to be an issue with the 7400 routine. Upon selecting it closes the entire app. Running IOS 16.3.1

Excellent 👍👍. Beautiful application to have, if you’re a service tech or just into electronics. Lots of good tools and information. Excellent support.

Great! But I wish it had support for vacuum tubes. Excellent app!! I repair all kinds of audio electronics and this saves me time during the repairs. It would be awesome if we could get tools for **VACUUM TUBES** added :D Please!!

Good Application. I really like this app and use it quite frequently when I'm in the design stage of an electronic project. It keeps me from having to surf the web when I come across something that's not in my head (and that's a lot). I'd give it 5 stars if the interface was just a little smoother.

Best Electronics App You'll Find. This app is packed full of all kinds of goodies. The developer is very dedicated to this app and is continuously updating and improving it. He listens to feedback and strives to make this app useful for all. It just keeps getting better.

DB conversion. Needs an added function, a DB to rms and a peak to peak conversion calculator with impedence factored in.

A great reference. This is a great app and a great reference tool. Being able to quickly see adjustments based on the values you are entering is a wonderful feature for real-life usage.

Flux capacitor. Seriously this is a fantastic resource even for a hobbyist like me. Usually you’d have to collect a variety of manuals or search for them. Not anymore. Thanks!

Great application for EE use. I use this app to assist me with homework and it doesn't disappoint. Instead of referencing all over the Internet, I am able to do quick searches and find the values I need. I would recommend this app to friends and colleagues.

AV & Staging folks heads up. Wire ampacity for feeder and distro calcs, speed of sound calc (for setting Delays) are awesome tools. Other useful stuff for gigs and repairing gear as well. Very handy!

EE ToolKit. Great app...Love It!

EE Toolkits. Great tool, everything I need in one spot that just works. I love it.

Impressive!!!. Excellent Tool! Big improvements in the latest version. Very well done!

Indispensable. As a fairly novice ham radio operator and electronics tinkerer, this app has been absolutely indispensable to me. It has been a great learning tool. If you are wondering if maybe it is too advanced for you, I thought the same. There are still many functions that I don’t understand (yet). But, as I progress with my understanding of electronics more and more of the functions become useful. The Function generator alone is worth the money. I use it all the time to generate Lissajous patterns on my oscilloscope. Also useful for testing cross overs on speakers. The resistor color band calculator is excellent as are the series and parallel component calcs. Looking forward to future updates, and to gaining a better understanding of the other functions.

Great Reference Tool. The author puts a lot of time into this app, and it shows. One of my favorite reference tools. I would like to see better "Open In" support for all results. pdf saving of results. Also, LateX to MathJax conversion utility.

Best Electronic app. I use this app all the time and love it. It makes my job easer with all the formulas in place. If you are in any electronic field of service you need this app!

The best tool for the field tech. Great tool, I can review my calculations with this tool when I was in the field thanks

Great App. This is a great app, well worth the money. If you're into electronics this is a must have.

Awesome App!. I am an Electrical Engineer and give this my full endorsement. Powerful tools, great interface and thoughtfully designed. I will use this in my audio design business. Kudos to the developer. This is a work of love!

Sweet Update!. I got this app when it first came out. It was a basic electronics tool. Of course, basic is a relative term because nobody else had thought to create one. The way you have supported, improved any upgraded it over the years is enough to restore my faith in humanity. I mean that sincerely. With everything from politics to terrorism to in app purchase, the future seemed dark, but you are the light of hope at the end of the tunnel! You, my friend, deserve a Nobel peace prize. Know that your efforts are truly appreciated! I do have one suggestion. In the LED Visible Spectrum section make the frequency counter color at the top of the page match the selected frequency.

Great app!! Please update SBC section :). The tools available in this handy app are incredible. Take the time to explore and experiment. Please add Teensy 4.1 to the SBC section.

Very handy App. I’ve been using the this app for a many years. It has always performed well. I am a professional electronic engineer. There are more features than I need. A great collection of converters, calculations, and general data. The Favorites page is great for organizing the 8 or 10 items I use all the time.

Best app for Engineers. Wow... This app is amazing last update added a super cool features. I normally don't review apps but this one deserve the best review from me. Very nice!!!

This is not geared towards the professional. This isn’t a bad app, overall it has a lot of helpful information, but the info is more geared towards amateurs/enthusiasts than actual engineers. I would recommend updating the UI to enhance navigation of the app. For example, implementing the function of swiping right from the left of the screen to go back a page rather than only being able to press the ‘X’ button would improve user experience.

Great. Very powerful tools, work often can be used to it

35 yr electronic tech. This app has everything I need for field work. It does lack connection pinouts, but other apps have that information. It would be nice to have it in one place -wink-dev

Thank You. Really AWESOME tool!. this App is extremely fast and stable, developer is very responsive, updates come in at a regular basis with really neat improvements. I used the basic version for some time, now switched to the Pro version. this app was great before, now it's even greater!

Lots of features, but. I think the UI could look a lot better (pictures, icons, layout, etc). And some parts aren't very intuitive. For example, I think the schematic in the LED calculator is kind of useless, and takes up too much space. It's be nice if the calculator just gave the resistor value rather than hiding it in the schematic

Best tool kit on the market!. No other tool kit can compare to the numerous formulas, calculators, diagrams, examples, and explanations this app contains. It contains all the information you need when making projects so there's no need to switch between other apps.

Awesome app, constant and powerful improvements. This app was worth every penny I paid for it back when I bought it years ago. Since then, I've regularly used it at work and found it to be an excellent, quick tool to use. The most impressive aspect of this app are the constant and VERY impressive updates! Massive feature additions and very easy to use interface! The list of capabilities this app has makes it an amazing value for truly anyone involved in electronics.

Best electronics app out there.. This app has it all. Easy to use and great UI. A ton of info and an invaluable tool for techs, students, and diy’ers.

hope. Chinese is not supported

Great. Very powerful applications, is an essential part of my application.

Pi pad calculator. Thank you for adding the option to add resistor values to create a pi-pad! Now the rest of the Technicians at my company can use values that we have in the stockroom to design pi-pads for our DDC product line. Big help! 😀 Mark

Has Almost Everything for EE!!!. Has more part types and information about electronics than any other App!!!

Simply brilliant. Large amount of useful information. Brilliant app, regular updates are always welcome

Handy reference and so much more. This app is great and just continues to get better and better. All the sort of things I need to know and now I don't have to look them up each time because they are on my phone.

Definitely worth it!. Such a great app! I use it all the time at work and it even comes in handy just in life. Couldn't be happier.

Most useful electronics tool. This is a great app. All the electronic formulas and data you would ever need in the one, easy to use app. It would be nice to have logarithmic up and down sweep frequencies as well as the standard linear sweep. Thanks for continually updating the app.

Boring and limited functionality. I was looking for an app that would be useful for second year electronics students. This app is more unit able for engineering technologists but leaves a lot to be desired for electronics engineers. ItronixPal has similar features.

Great App. This is a great app. Very easy to use and useful for the professional or hobbies enthusiast.

Must have for electronics engineer. Very handy tool for quick calculations. Highly recommended for all electronics engineers.

This app has evolved allot. I bought this app in its early days and since then it has evolved into a quality app. Exactly what a mad scientist such a myself needs. Hope it will continue to evolve, so far the author has been receptive to suggestions and resolving issues. Keep up the good work, your ongoing work has been noticed and appreciated.

Lots of useful data. The last update does not acknowledge that the update is installed this is an irritation. Apart from that the app contains many useful tables and calculators.

Unreal. Lots of good useful tools.

Excellent. I use this reference all of the time.

Amazing. Amazing app simply perfect for anything to do with electronics. I run a cell phone repair shop and this tool is invaluable in my day to day operations. A big tip of my hat to the developer

Good stuff. Big improvements from the last version. Much faster, organized, and prettier. Very useful for students!

Very good app but. There are some mistakes on different sections of this app. For instance when it calculates a simple led circuit with 24 input voltage, instead of writing 220 ohm for the resistor value it shows 266 kilo ohm

A solid app with great support. Updated to iOS 8 & appreciated. A dedicated and serious developer. I'm an instrument technician, who needs electrical information & calculations at my fingertips. Hope to see more in the future.

A tool to keep in hand. Has lots of info and handy when needed.

Great. Excellent! Nice application for technical personnel,but need to improve graphics part.

Great app but too big!. I have had this app for a very long time. I recently deleted it because it was huge! I needed the voltage divider real quick and went to download it again. It's 190 mb! That's just too big for me.

Great App. Very cool.

Great app. Very concise. Has most everything needed.

Excellent. Worth every penny

Good app. Good app

Mejor no lo hay!!. Es una maravilla como trabaja esta app, el simulador es perfecto y las fórmulas son auténticas, yo no tengo ningún aprendizaje en electrónica, pero desde que abrir esta application me sosprendio y me interesa recibir alguna clase básicas en electrónica , me recomendarías algún curso básico?

Great App!!!!! 5 STARS!!!!!. I'm a self employed technician who runs a company selling and servicing High Power Amplifiers (Klystrons and TWTs) for the Satellite Broadcast Industry. Being a technician (as opposed to a degreed engineer) I find myself looking up a number of things when it comes to repairing a new or unfamiliar circuit. A number of times, I need a formula that I don't use often enough to memorize and it takes time to figure out exactly where I should begin solving my (or the customer's) problem. Some things I've created short cuts in my head to use as I do them all the time, but for those things that I don't keep in my head, this app either fills the gap or has the potential to!!! Each subsection is laid out nicely for data input and has a sample entry to quickly give you the gist of entering the data. An INFO icon in the lower right hand corner takes you to a page giving the formulae used in the calculation process. Granted, there are no descriptions of the variables on this page, but if you need to go much past the data entry page to get the info you want, you should probably get out your Electronic Engineer's Handbook anyway! This app is for getting a quick answer to an immediate concern!!! As it grows and the writer adds more and more functionality, I'm sure this will become a "Technician's Best Friend!!!" It's well worth the few dollars you spend on it as time is money!!! The writer, Tom Gruber, is also very responsive to his customers! I sent him a note saying that I liked his app and made a few suggestions for expansion. In less than 24 hours I heard back from him! That's service!!! This App has the potential to be an Engineering Handbook in your pocket!!! It's well on its way to being that now!!! I highly recommend you purchase this app and if you don't see something you need…ASK!!! I'm sure Tom will do his level best to accommodate your needs!!! After all…being quicker and more productive is what technology is all about! This app will help you be your best!!!!!

Awesome!. If your in electronics you need this app!

Great. Really is a very practical application, the price is right.. Like it very much

Don't buy. The ohms law calculator does not calculate the right answer. Really! If you put r at 4000 ohms and volts at 4 you get the current displaying 4000 amps. I wish I could take a screen shot.

Not what I expected. It's pretty handy but there's some free apps that I like better. Sorry bro

Great app. Everything you need about electronic its here :)

Save your money. This is the worse purchase I have ever made!

Great. Very powerful application, occasionally will use it, gave me great help

Pretty good. Some things are quite small to fit the phone screen, so a zoom in/out would be really nice. The circuits make the assumption of familiarity- a key of simple “what is” and/or suggested choices on many components would be awesome. I thought I had seen a resistor code ref here (bands / surface mount), but can’t find (would be great using camera 😊 ). Lastly there is so much here that a textual index would be handy on the main page for a quick jump to a specific “page”... or maybe an option for a hierarchical contents for the top page?

Update. Seguir mejorando. Añadir más pinout, por ejemplo

Handy. Does what it does. No 5th star because that is reserved for magic
