# Resistor color code calc vs AI Resistor Color Code Scanner

The clearest difference is rating: Resistor color code calc at 5.0 against AI Resistor Color Code Scanner's 3.0. Resistor color code calc also leads on in-app purchases (none vs 1) and ratings volume (5 vs 1). AI Resistor Color Code Scanner's advantage is ads (none vs shown) and update cadence (every 5 weeks vs every 3 months). On price there is nothing between them.

Both are free to download. AI Resistor Color Code Scanner sells 1 one-off in-app purchase. Resistor color code calc asks for nothing beyond the download.

Resistor color code calc holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Resistor color code calc has 5 ratings behind it against 1, so its average is the more settled of the two.

Resistor color code calc ships an update every 3 months, AI Resistor Color Code Scanner every 5 weeks. The most recent releases landed on September 10, 2026 and September 3, 2026 respectively.
