If I had to, I could not find a complaint. --------------- This app is intuitive, clear, concise and accurate. -------------- It is Feature Packed! Having the Search function (where one enters the resistor value, tolerance & temperature coefficient to get the color code) is very handy when working "backwards". The Cheat Sheet (under the Table tab) is also handy for those of us who forget things faster than we remember them! ------------ One may also move the app to the SD card to save phone storage space- a welcome feature. The ads are minimal and easy to dismiss- but they don't get in the way.------- I have tried several (since I can never find my charts) and this one tops them all. I think you will enjoy it.

The design of this app is absolutely flawless! I installed and tried multiple resistor color code apps, but this one is by far the best. The interface is clean, fast, and very easy to use. It accurately calculates resistor color codes and SMD markings, making it an excellent tool for electronics students, hobbyists, and professionals. Highly recommended for anyone working with electronic components!
