Ratings and reviews

This is the best electronic app I have seen in the Play Store. I will be starting breadboarding in about a week, This app will be open and ready for work on my desk. This app would make a great reference book!

A very powerful handy reference tool in my hand. I am in the automotive industry and this package of very important data is just worth carrying around on my phone for quick reference. A wonderful app . Keep on improving it.

Love the app. Suggestion for enhancement - the possibility to export the graphic layouts to some full page format for printing (pdf? jpg? png?). I'd pay another 49¢ for this capability!

What’s new

Added Silicon Controlled Rectifier (SCR/Thyristor), Unijunction Transistor (UJT), Boost Converter Calculator, Buck Converter Calculator, and Colpitts Oscillator. Fixed a few bugs.
