# RC Circuit vs Electronic Component Codes

The clearest difference is in-app purchases: Electronic Component Codes at none against RC Circuit's 1. Electronic Component Codes also leads on update cadence (every 6 weeks vs every 6 months). RC Circuit's advantage is ads (none vs shown) and iOS requirement (12.0 vs 16.0). On price and device support there is nothing between them.

Both are free to download. RC Circuit sells 1 one-off in-app purchase. Electronic Component Codes asks for nothing beyond the download.

RC Circuit ships an update every 6 months, Electronic Component Codes every 6 weeks. The most recent releases landed on October 5, 2026 and October 1, 2026 respectively.
