# Sleep Cycle vs SleepSpace

The clearest difference is rating: Sleep Cycle at 4.7 against SleepSpace's 4.2. Sleep Cycle also leads on ratings volume (31K vs 858) and chart position (#49 vs unranked). SleepSpace's advantage is review sentiment (57% vs 40%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sleep Cycle sells 9 in-app purchases, starting at $2.99 per month and SleepSpace sells 13 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Sleep Cycle holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Sleep Cycle has 31K ratings behind it against 858, so its average is the more settled of the two. Written reviews complicate that: 40% of Sleep Cycle's written reviews are positive against 57% of SleepSpace's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 31, 2026 and October 29, 2026 respectively.
