Verdict

The call

The clearest difference is rating: 小猫睡眠 at 5.0 against SleepSafe's 4.5. SleepSafe's advantage is review sentiment (100% vs 65%). On price, ratings volume, update cadence and ads there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. SleepSafe sells 2 in-app purchases, starting at $6.99 per month and 小猫睡眠 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

小猫睡眠 holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 11 and 8 respectively. Written reviews complicate that: 100% of SleepSafe's written reviews are positive against 65% of 小猫睡眠's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SleepSafe ships an update every 2 weeks, 小猫睡眠 weekly. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
