What we like: Our wristband pick for tracking both sleep and activity. Offers accurate sleep and heart-rate data, and our test found its sleep data to be accurate as well. Tracks more fitness-related metrics than our top pick. Lightweight woven wristband was comfortable all day and during sleep. Comes with 12-month subscription to Whoop.
Other things to know: Ideal for wearers who don’t mind inputting a lot of data into the app, which can be intimidating. Battery lasts up to 5 days. Water-resistant. Requires a $239 annual subscription (or $399 for two years), but fees are FSA-eligible, and comes with a 12-month subscription with purchase. Although it says it’s only for new members, the 12-month sub also works as a renewal/membership extension if you already have one.
