# Arduino Pocket Reference vs AVR Projects

The clearest difference is ads: AVR Projects at none against Arduino Pocket Reference's shown. AVR Projects also leads on update cadence (daily vs every 5 months). Arduino Pocket Reference's advantage is iOS requirement (14.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Arduino Pocket Reference sells 1 one-off in-app purchase and AVR Projects sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Arduino Pocket Reference ships an update every 5 months, AVR Projects daily. Both last shipped on October 12, 2026.
