# Eight Sleep vs SunSmart Cloud 2.0

The clearest difference is rating: Eight Sleep at 4.8 against SunSmart Cloud 2.0's 3.0. Eight Sleep also leads on update cadence (every 3 days vs every 6 weeks) and ratings volume (18K vs 2). SunSmart Cloud 2.0's advantage is review sentiment (47% vs 28%) and iOS requirement (12.4 vs 17.0). 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 SunSmart Cloud 2.0 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Eight Sleep holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Eight Sleep has 18K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 28% of Eight Sleep's written reviews are positive against 47% of SunSmart Cloud 2.0's, so the app with the better star average is not the one people write more warmly about.

Eight Sleep ships an update every 3 days, SunSmart Cloud 2.0 every 6 weeks. The most recent releases landed on October 21, 2026 and October 14, 2026 respectively.
