“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.

What's New

Version 8.1.0

New File Manager! Simply save and load your calculations!

The EE ToolKit now features an integrated File Manager. For every tool there is now the option to save as many calculations as you want to and re-load them at any later point in time. Just tap on the folder icon in the sidebar menu and the browser will appear. After saving, the data is stored locally in the App and also synced in iCloud, so it even transfers to your other devices running the same App.

Like for the universal build of the EE ToolKit App (that's the free version with In-App purchase to PRO), you can save a calculation on your iPhone and later on open the same calculation on your iPad or vice-versa.

Or if you run the 'EE ToolKit for iPad' version on your iPad Mini and on an iPad Pro, these two will sync all saved calculation data. But please note that this feature is tied to your iCloud account, your Apple-ID. You cannot transfer calculation data between different iCloud accounts!

Editing is also straightforward. In the File Manager, just swipe left on a row and you will be given the option to rename a calculation, or to delete it.

Other Changes:
• updated links to NXP datasheets. NXP is now Nexperia.
• iPad menu structure changed (now with sidebar just like on iPhone)
• other improvements and smaller fixes

Thank you very much for using the EE ToolKit! If you have a moment, please leave a review in the App Store. With this, you are really helping a lot so we can further develop and improve the App. Thank you so much! - tom

Ratings and Reviews

Waste money!


Very basic! Get another app

Informative and accurate calculator


This app has really helped my study circuit components that I haven't had much exposure to while also serving as a tool for calculating component values in circuits I use all the time.

I wish there was a category for transformers, inductors, and electromagnetism though. It would also be cool if they included audio applications of the 555 timer.

Overall my favorite circuit calculating app I've found so far.

EE Toolkit - Best App Ever


This program is why I own an iPad. Having EE Toolkit on my bench has helped me become more productive and creative with electronic design work. The time and effort it must have required to build an app of this nature is truly amazing.

Beginners will benefit from the clear explanations and logical graphics and experts will love that everything is at their fingertips.

Many thanks to the creators of this fine program!!!
