# Arduino Programming Tutorial vs PLC AI

The clearest difference is in-app purchases: Arduino Programming Tutorial at none against PLC AI's 16. Arduino Programming Tutorial also leads on review sentiment (45% vs 29%). PLC AI's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days. Arduino Programming Tutorial asks for nothing beyond the download.

Arduino Programming Tutorial ships an update every 6 weeks, PLC AI every 3 weeks. The most recent releases landed on September 23, 2026 and August 27, 2026 respectively.
