“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.

Not bad for the price

This app holds a great deal of promise if the library collection keeps expanding and the routines are generalized to electrical engineering. For example a transformer section would be nice. Power factor, kvar, kva and kw calculations lend themselves to this sort of thing if the load can be adjusted as well as the factors.

My only negative comment is about the interface. It is a mess. The backgrounds detract from the calculations and the notes look pasted on. Try and keep the controls in the same region on each worksheet and put notes in a separate region. The elementary drawings with results should have the focus which implies the middle area. The focus needs the brightest background. The other regions could be left/right or top/bottom. These are just my thoughts on the interface but in general I applaud the effort so far.

4/5 stars

Another Useful Addition to the iPad Toolset

Great, easy to use tool for many basic EE design functions. It will get better as more features are added. Replaces a long collection of bookmarks from assorted on-line referencesa and calculators in one easy to use format.
