# Electronic Component Codes vs Resistor

The clearest difference is ads: Resistor at none against Electronic Component Codes's shown. Resistor also leads on monetization model (free vs ad-supported). Electronic Component Codes's advantage is update cadence (every 6 weeks vs every 9 months) and iOS requirement (16.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Electronic Component Codes ships an update every 6 weeks, Resistor every 9 months. The most recent releases landed on September 16, 2026 and August 27, 2026 respectively.
