# Yi iot vs Smaint

The clearest difference is rating: Smaint at 4.0 against Yi iot's 3.1. Smaint also leads on in-app purchases (none vs 10) and iOS requirement (11.0 vs 13.0). Yi iot's advantage is ratings volume (5K vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Yi iot sells 10 in-app purchases, starting at $9.99 per month. Smaint asks for nothing beyond the download.

Smaint holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: Yi iot has 5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 5% of Yi iot's written reviews are positive against 0% of Smaint's, so the app with the better star average is not the one people write more warmly about.

Yi iot ships an update every 2 weeks, Smaint every 3 weeks. The most recent releases landed on November 10, 2026 and November 3, 2026 respectively.
