# iSleeper vs PeeTime

The clearest difference is rating: PeeTime at 4.6 against iSleeper's 3.3. PeeTime also leads on update cadence (every 5 days vs every 3 weeks). iSleeper's advantage is review sentiment (89% vs 60%) and device support (4 vs 2). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. iSleeper sells 3 in-app purchases, starting at $1.99 per month and PeeTime sells 4 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

PeeTime holds the better App Store score, 4.6 against 3.3. Both are backed by a comparable volume of ratings — 7 and 9 respectively. Written reviews complicate that: 89% of iSleeper's written reviews are positive against 60% of PeeTime's, so the app with the better star average is not the one people write more warmly about.

iSleeper ships an update every 3 weeks, PeeTime every 5 days. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
