# Pillow vs Eight Sleep

The clearest difference is rating: Eight Sleep at 4.8 against Pillow's 4.4. Eight Sleep also leads on update cadence (every 3 days vs every 10 days). Pillow's advantage is review sentiment (42% vs 29%) and chart position (#129 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pillow sells 6 in-app purchases, starting at $19.99 per month and Eight Sleep sells 4 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.

Eight Sleep holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 18K, so its average is the more settled of the two. Written reviews complicate that: 42% of Pillow's written reviews are positive against 29% of Eight Sleep's, so the app with the better star average is not the one people write more warmly about.

Pillow ships an update every 10 days, Eight Sleep every 3 days. Both last shipped on October 30, 2026.
