One-liner
A simple, fast tool for decoding resistor color codes and calculating resistance values from band colors.
Strengths
- Fast and accurate color code interpretation with real-time results
- Clean, minimal interface optimized for quick use in electronics work
- Supports 4-band, 5-band, and 6-band resistors (as noted in reviews)
- No ads or in-app purchases—users appreciate the straightforward experience
- Highly rated for reliability and precision in technical calculations
Weaknesses
- Only 8 reviews—limited user feedback indicates low visibility or adoption
- No support for tolerance bands beyond standard ±1%, ±2%, etc. (missing in review comments)
- No visual aid for color blindness (user complaint: 'hard to distinguish red/green')
- No export or save history feature (review: 'wish I could save my last few calculations')
- No integration with component databases or shopping links (missed opportunity)
Opportunities
- Add color-blind-friendly palettes and high-contrast mode
- Introduce a 'recent calculations' history with export/share options
- Build a companion app that pairs with this one—e.g., 'Resistor Finder' with part numbers and pricing
- Add support for SMD/numeric coding alongside color bands
- Integrate with popular electronics platforms (e.g., KiCad, Tinkercad) via API or import
Competitors
- Resistor Color Code Calculator by Digi-Key
- Electronics Toolbox by Aether
- Ohm's Law Calculator by AppCrate
