# Arduino Programming Tutorial vs AVR Projects

The clearest difference is in-app purchases: Arduino Programming Tutorial at none against AVR Projects's 10. AVR Projects's advantage is ads (none vs shown) and update cadence (daily vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. AVR Projects sells 10 one-off in-app purchases. Arduino Programming Tutorial asks for nothing beyond the download.

Arduino Programming Tutorial ships an update every 6 weeks, AVR Projects daily. The most recent releases landed on October 12, 2026 and September 26, 2026 respectively.
