# 蜗牛睡眠 vs iSleeper

The clearest difference is rating: 蜗牛睡眠 at 4.1 against iSleeper's 3.3. 蜗牛睡眠 also leads on ratings volume (202 vs 7) and iOS requirement (13.0 vs 15.0). iSleeper's advantage is ads (none vs shown) and review sentiment (89% vs 58%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 蜗牛睡眠 sells 13 in-app purchases, starting at $5.99 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.

蜗牛睡眠 holds the better App Store score, 4.1 against 3.3. That said, the two scores are not equally well evidenced: 蜗牛睡眠 has 202 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 58% of 蜗牛睡眠'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.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
