# Circuitry vs Arduino Programming Tutorial

The clearest difference is ads: Circuitry at none against Arduino Programming Tutorial's shown. Circuitry also leads on monetization model (free vs ad-supported) and review sentiment (54% vs 45%). Arduino Programming Tutorial's advantage is update cadence (every 6 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Circuitry ships an update every 4 months, Arduino Programming Tutorial every 6 weeks. The most recent releases landed on September 13, 2026 and September 23, 2026 respectively.
