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 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.

A pleasure to use!

I had a lot of these types of apps on my iPad, after looking at and using this (latest) release I have deleted all but EE ToolKit. It has everything I need. Well thought out, a pleasure to use.
