Verdict
The clearest difference is rating: Sleepzy at 4.3 against zZz's 2.9. Sleepzy also leads on review sentiment (37% vs 0%) and ratings volume (22K vs 11). zZz's advantage is ads (none vs shown) and update cadence (every 4 days vs monthly). On price, in-app purchases and monetization model 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
Both are free to download. Sleepzy sells 13 in-app purchases, starting at $3.99 per 7 days and zZz sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Sleepzy holds the better App Store score, 4.3 against 2.9. That said, the two scores are not equally well evidenced: Sleepzy has 22K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 37% of Sleepzy's written reviews are positive against 0% of zZz's.
Sleepzy ships an update monthly, zZz every 4 days. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
