# Eight Sleep vs InsideTracker

The clearest difference is rating: Eight Sleep at 4.8 against InsideTracker's 3.4. Eight Sleep also leads on ratings volume (17K vs 341) and update cadence (every 4 days vs fortnightly). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Eight Sleep sells 4 in-app purchases, starting at $10.00 per month and InsideTracker sells 2 in-app purchases, starting at $149.00 per year. Whichever you choose, the download price is not the number that matters.

Eight Sleep holds the better App Store score, 4.8 against 3.4. That said, the two scores are not equally well evidenced: Eight Sleep has 17K ratings behind it against 341, so its average is the more settled of the two. Written reviews complicate that: 28% of Eight Sleep's written reviews are positive against 33% of InsideTracker'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, InsideTracker fortnightly. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
