Resistor Code Calculator

Good little app that does exactly what you need it to - visually decoding/encoding the values and color bands of resistors. In that aspect, it’s flawless. Five+ years later, though, and I still can’t figure out why every so often it asks me to grant Bluetooth access permission 🤔

Extremely helpful for standard resistors with four color bands. Would be nice to have a 5 band option. I would pay if the app allowed the camera to ID the colors, if fast and reliable.

Simple is as simple does, this app translates the resistor color codes to numeric form on one easy-to-use page; I love it. Caution: you really need a reliable multimeter to verify that the resistor you have actually measures correctly, as it may have been overheated or otherwise incorrect.
