# Sleep Timer vs Sleepzy

The clearest difference is monetization model: Sleepzy at freemium against Sleep Timer's subscription. Sleepzy also leads on ratings volume (22K vs 1.5K) and device support (4 vs 2). Sleep Timer's advantage is ads (none vs shown) and rating (4.7 vs 4.3). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Sleep Timer sells 10 in-app purchases, starting at $1.99 per 7 days and Sleepzy sells 13 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sleep Timer holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Sleepzy has 22K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews point the same way: 57% of Sleep Timer's written reviews are positive against 37% of Sleepzy's.

Sleep Timer ships an update every 2 months, Sleepzy monthly. Both last shipped on November 1, 2026.
