Verdict

The call

The clearest difference is rating: Eight Sleep at 4.8 against Pillow's 4.4. Eight Sleep also leads on update cadence (every 4 days vs every 2 weeks). Pillow's advantage is review sentiment (41% vs 27%) and chart position (#149 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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 17K, so its average is the more settled of the two. Written reviews complicate that: 41% of Pillow's written reviews are positive against 27% of Eight Sleep's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pillow ships an update every 2 weeks, Eight Sleep every 4 days. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
