Sleep tracking you forget you're wearing, behind a monthly fee that continues for as long as you want the data. The hardware is widely liked; the subscription is the entire argument.
This entry is written from the 4 sources listed at the bottom of the page. The numbers are our editorial estimates drawn from that material, not measurements, and no statistical sample sits behind them.
It depends on how you will use it. 66% would buy it again, which means roughly 34% would not. Total cost over several years is far above the sticker price.
Interest in the daily score usually settles, and the monthly charge starts being weighed against how often the app actually gets opened.
Total cost over several years is far above the sticker price. Battery capacity declines and the ring is not serviceable. Competitors now offer similar tracking with no subscription.
Worth it for: People specifically tracking sleep; Anyone who won't wear a watch overnight; Users who'll act on the data rather than just collect it. Think twice if: You dislike subscriptions on hardware you own; You already wear a tracking watch; You'd stop looking at the app after a month.
