# Eight Sleep vs Willowave

The clearest difference is review sentiment: Willowave at 83% against Eight Sleep's 27%. Willowave also leads on iOS requirement (15.1 vs 17.0). Eight Sleep's advantage is rating (4.8 vs 4.3) and update cadence (every 4 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Eight Sleep sells 4 in-app purchases, starting at $10.00 per month and Willowave sells 6 in-app purchases, starting at $6.99 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 4.3. That said, the two scores are not equally well evidenced: Eight Sleep has 17K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 27% of Eight Sleep's written reviews are positive against 83% of Willowave's, so the app with the better star average is not the one people write more warmly about.

Eight Sleep ships an update every 4 days, Willowave monthly. The most recent releases landed on September 25, 2026 and June 14, 2026 respectively.
