Ratings and reviews

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.

resistor for the 4th band or tolerance band, doesnt give you a complete selection. I couldnt enter "none" or 20% in the tolerance spot. kinda defeats the purpose of the app If you cant use that. everything else seemed cool.

Spot on. Wish I could just point the camera on a cross hair and have it spit out the value. Reading ICs and a built in cross reference would be nice too.
