## Description

Calculate resistor color codes with this handy reference app. The app is useful for the maker, engineer, student and arduino or raspberry pi tinkerer when working with electronics.

Supports 4 and 5-band resistors!

The industry standard color-code is used to identify the resistance value of resistors used in all kinds of electronics.

## Rankings

- #243,452 — Overall

## Review summary

Users praise the app for its simple, clean UI and clear visual mapping of resistor color codes, making it a handy, free learning tool. However, reviews note frustrations with ads and privacy-related permissions, plus requests for more features (notably 5-band support and a settings option). Overall, the app is valued for ease of use but hindered by monetization, privacy concerns, and feature gaps.

### Pros

- Simple, easy-to-use, one-page UI that clearly displays resistor color codes and their numeric values.
- Visually decodes/encodes color bands in a straightforward way, making it easy to see results at a glance.
- Free to use and helpful for learning and memorizing resistor color codes.

### Cons

- Ads are intrusive/obtrusive and increased after updates, affecting the user experience.
- Privacy concerns due to tracking and unsolicited Bluetooth permission requests.
- Missing features: only 4-band mode with no obvious way to switch to 5 bands or access settings.
