About EE ToolKit

This is the brand-new Electronics Engineering ToolKit! The HIGHLY RATED and RECOMMENDED productivity app.

Users say it is the BEST and MOST PRACTICAL Electronics App in the whole App Store.

From an electronics enthusiast with a master's degree in Electronics Engineering. This App is for engineers, students and hobbyists and anyone interested in Electronics Engineering.

The App gets CONSTANT and POWERFUL improvements!

!!! This is a UNIVERSAL App - for iPhone and iPad !!! With In-App upgrade to PRO. If you don't like In-App purchases, you can also download the PRO version (red icon with PRO text) which is full PRO from the beginning without any In-App purchase.


WHAT OTHER USERS ARE SAYING:

“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.

“Latest version makes this an exceptional tool”
The EE Toolkit was always a very useful tool, but with the additions in the latest version it is truly an exceptional tool. The author is extremely diligent in managing bugs and improving the tool.

“A superb app highly recommended”
Fantastic application. Very useful. Always updated. Good developer. Lots of great bonus tools. Just love it.

"Incredible useful, worth the money"
I have had this app for a while now. Originally as an Electrical Engineering student I didnt really use it but once I was out in the field it became my bible. I definitely recommend to any engineering students/professionals alike. I also recommend buying the Pro version because it is definitely worth it.
