# Arduino Pocket Reference vs Electronic Circuits Calculator

The clearest difference is in-app purchases: Electronic Circuits Calculator at none against Arduino Pocket Reference's 1. Electronic Circuits Calculator also leads on update cadence (every 2 months vs every 5 months). Arduino Pocket Reference's advantage is review sentiment (12% vs 0%) and iOS requirement (14.0 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. Arduino Pocket Reference sells 1 one-off in-app purchase. Electronic Circuits Calculator asks for nothing beyond the download.

Arduino Pocket Reference ships an update every 5 months, Electronic Circuits Calculator every 2 months. The most recent releases landed on June 2, 2026 and August 27, 2026 respectively.
