# Easy Ohm's Law vs Arduino Programming Tutorial

The clearest difference is rating: Arduino Programming Tutorial at 3.0 against Easy Ohm's Law's 1.5. Arduino Programming Tutorial also leads on in-app purchases (none vs 1). Easy Ohm's Law's advantage is ads (none vs shown) and review sentiment (69% vs 45%). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. Easy Ohm's Law sells 1 one-off in-app purchase. Arduino Programming Tutorial asks for nothing beyond the download.

Arduino Programming Tutorial holds the better App Store score, 3.0 against 1.5. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 69% of Easy Ohm's Law's written reviews are positive against 45% of Arduino Programming Tutorial's, so the app with the better star average is not the one people write more warmly about.

Easy Ohm's Law ships an update every 3 months, Arduino Programming Tutorial every 6 weeks. The most recent releases landed on October 10, 2026 and October 23, 2026 respectively.
