Cons
- Sleep stage accuracy trails Fitbit and Garmin in side-by-side comparisons

- No SpO2 trend graphing as robust as the pricier competitors
Best for consistent nightly wear thanks to the longest battery life of the group, with solid but not class-leading sleep detail.
The best data on your sleep only counts if the tracker is comfortable enough to actually leave on your wrist all night.
Sleep tracking sounds simple on a spec sheet, but the trackers that produce the most useful morning sleep score combine consistent hardware with software that translates raw numbers into something actionable.
In testing, the Fitbit Charge 6's Sleep Score gave the clearest single daily number, folding sleep stages, restlessness, and duration into an easy read, starting at $159.95.
The Garmin Vivosmart 5 took a different approach, tying overnight recovery directly into its Body Battery metric with no subscription required to see the full picture.
For anyone who wants to wear a tracker to bed every single night without thinking about the charger, the Amazfit Band 7's 18-day battery life removes that friction almost entirely, at under $50.
The Best Sleep Trackers at a Glance
Best overall: Fitbit Charge 6, the clearest daily Sleep Score and the most complete overnight metrics.
Best for recovery context: Garmin Vivosmart 5, Body Battery ties sleep directly to a free daily energy number.
Best for nightly wear: Amazfit Band 7, 18-day battery life removes charging friction almost entirely.
What Actually Matters for Sleep Tracking
Comfort overnight. A bulky or stiff band that digs into the wrist during side sleeping undermines the entire point. Slim, flexible bands like the Amazfit Band 7's perform noticeably better for side sleepers.
Charging schedule. Trackers with shorter battery life need a dedicated charging window, typically during a morning shower or workout, that doesn't conflict with bedtime.
How the app presents the data. A sleep score is only useful if it's easy to read at a glance each morning. Fitbit and Garmin both do this well; budget apps tend to bury the useful summary under raw charts.
