# Arduino Programming Tutorial vs Circuit Simulator

The clearest difference is in-app purchases: Arduino Programming Tutorial at none against Circuit Simulator's 8. Circuit Simulator's advantage is ads (none vs shown) and review sentiment (73% vs 45%). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Arduino Programming Tutorial asks for nothing beyond the download.

Both ship on a similar rhythm, roughly every 6 weeks. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
