# Sleep vs Sleep Tracker

The clearest difference is monetization model: Sleep Tracker at free with in-app purchases against Sleep's subscription. Sleep Tracker also leads on rating (4.6 vs 4.3). Sleep's advantage is ads (none vs shown) and ratings volume (9.8K vs 34). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Sleep sells 12 in-app purchases, starting at $2.99 per 7 days and Sleep Tracker sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sleep Tracker holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Sleep has 9.8K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 60% of Sleep's written reviews are positive against 50% of Sleep Tracker's, so the app with the better star average is not the one people write more warmly about.

Sleep ships an update every 3 weeks, Sleep Tracker every 11 days. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
