# Sleep Time vs SleepSpace

The clearest difference is ads: SleepSpace at none against Sleep Time's shown. SleepSpace also leads on update cadence (weekly vs monthly) and device support (3 vs 1). Sleep Time's advantage is rating (4.7 vs 4.2) and review sentiment (76% vs 57%). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sleep Time sells 8 in-app purchases, starting at $4.99 per month and SleepSpace sells 10 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Sleep Time holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Sleep Time has 5.4K ratings behind it against 860, so its average is the more settled of the two. Written reviews point the same way: 76% of Sleep Time's written reviews are positive against 57% of SleepSpace's.

Sleep Time ships an update monthly, SleepSpace weekly. Both last shipped on November 6, 2026.
