# Sleepzy vs Rem

The clearest difference is ads: Rem at none against Sleepzy's shown. Sleepzy's advantage is ratings volume (22K vs 2.7K) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Sleepzy sells 10 in-app purchases, starting at $3.99 per 7 days and Rem sells 8 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.3 for Sleepzy against 4.2 for Rem. That said, the two scores are not equally well evidenced: Sleepzy has 22K ratings behind it against 2.7K, so its average is the more settled of the two. Written reviews split almost evenly too, at 37% and 38% positive.

Sleepzy ships an update monthly, Rem every 6 weeks. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
