# Tempur® Sleeptracker vs COZZIA

The clearest difference is rating: Tempur® Sleeptracker at 4.7 against COZZIA's 2.1. Tempur® Sleeptracker also leads on ratings volume (35K vs 7). COZZIA's advantage is review sentiment (50% vs 38%) and iOS requirement (12 vs 17.5). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Tempur® Sleeptracker holds the better App Store score, 4.7 against 2.1. That said, the two scores are not equally well evidenced: Tempur® Sleeptracker has 35K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 38% of Tempur® Sleeptracker's written reviews are positive against 50% of COZZIA's, so the app with the better star average is not the one people write more warmly about.

Tempur® Sleeptracker ships an update every 3 months, COZZIA every 6 weeks. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
