# 小睡眠 vs iSleeper

The clearest difference is rating: 小睡眠 at 4.7 against iSleeper's 3.3. 小睡眠 also leads on ratings volume (642 vs 7) and update cadence (every 9 days vs every 3 weeks). iSleeper's advantage is ads (none vs shown) and review sentiment (89% vs 75%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 小睡眠 sells 24 in-app purchases, starting at $0.99 per month and iSleeper sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

小睡眠 holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: 小睡眠 has 642 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 75% of 小睡眠's written reviews are positive against 89% of iSleeper's, so the app with the better star average is not the one people write more warmly about.

小睡眠 ships an update every 9 days, iSleeper every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
