eTools PRO App Reviews

Such a thorough and helpful resource for those never ending circuit questions.

Theres so many things in this app, it helps tremendously.

Great tool. Enjoy the plethora of information . Use it daily. Indispensable. Keep up the good work. WORTH CHECKING OUT !!

Very happy about this app!

Great app for calculations, as well as reference. One thing would be nice though: start adding additional Datasheets for other devices. For example; more micro-controllers, and micro-processors, Datasheets for regulators, transistors, diodes etc.

I need to build a power supply for an audio component in a Pi build. eTools is the first app I used to begin this project. Period.

The information in this app is Great. Recommend big time!!!

Please add an magnetic Amplifier calculator & a Cockroft–Walton generator calculator for more fun with this app Thanks!

Clean interface with all the content you could ask for. Great app!

All the pin outs I need in one place, without needing an internet connection! A must-have for all techs and tinker-ers!

The content of this app is fantastic! Really useful!

This is one of the most useful apps Ive downloaded from the app store is worth every six dollars even if it was $27 I would still buy it but this is a highly recommended app and no Im not writing this just to promote the app because I get paid Im writing this because this is helped me a lot in what I do

Thanks it is very useful, and have a great data sheet reference.

Really a great app. I dont even use it to its fullest. I generally only use the pinouts. Great layout. Great aesthetics. Works perfectly. I show it off to my co workers all the time.

Its amazing all the info you get from this app

The ultimate electronics cheat sheet on a smart phone. This is well worth the purchase!

I am a HAM operator and like not having to do calculus this app makes circuit design easy

This is the best and most helpful app for electronics!

Great app for all Signal Railroaders for working on signal designs in electronics, Thanks Tony D.

Fairly easy to use and a great app. Could use some adoptions and other material but a great app
