Resistor Code Calculators vs SMD decoder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Resistor Code Calculators
Read full descriptionHide full description
The one handy app for electrical engineering calculation. This app contains not only resistor color code and capacitor code calculators but also electrical filter, attenuator, rectifier, LC oscillator, RF, PCB trace, cable, Ohm's Law, skin effect, Lumen Candela conversion, Delta Y Conversion, and many other handy calculators.
SMD decoder
Decode SMD resistors with this practical tool. It supports three-digit, four-digit, and EIA-96 encoded resistor values, providing quick and accurate identification.
- Decodes 3-digit SMD codes
- Decodes 4-digit SMD codes
- Decodes EIA-96 SMD codes
- Resistor value identification

Verdict
The clearest difference is ads: SMD decoder at none against Resistor Code Calculators's shown. SMD decoder also leads on update cadence (every 2 days vs every 7 months) and iOS requirement (11.0 vs 13.4). On price, in-app purchases and device support there is nothing between them.
