# Pillow vs Sleep Details

The clearest difference is ratings volume: Pillow at 96K against Sleep Details's 1.1K. Pillow also leads on update cadence (every 2 weeks vs every 2 months) and chart position (#159 vs unranked). Sleep Details's advantage is review sentiment (50% vs 41%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Pillow sells 6 in-app purchases, starting at $19.99 per month and Sleep Details sells 3 in-app purchases, starting at $2.99 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 — 4.4 for Pillow against 4.4 for Sleep Details. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 1.1K, so its average is the more settled of the two. Written reviews are what separate them: 41% of Pillow's written reviews are positive against 50% of Sleep Details's.

Pillow ships an update every 2 weeks, Sleep Details every 2 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
