Wear the Samsung Galaxy Watch 7 to bed, and in the morning it tells you how long you slept, whether you snored, and if your breathing stopped at any point during the night. Take it on a run, and it counts your pace and maps your route on dual-frequency GPS. All of that comes off the BioActive sensor pressed against the underside of your wrist, which also reads ECG, blood oxygen, skin temperature, and body composition. Back Market is selling the green model with a 40mm aluminum case that survives dust and water down to 50 meters, and the Exynos W1000 inside gets about two days out of a charge.

A smartwatch with dozens of ways to handle your day
Samsung focused its health monitoring capabilities as the core of this smartwatch. The BioActive sensor monitors heart rate, ECG, blood oxygen saturation, and skin temperature, in addition to body composition readings that estimate muscle mass and body fat percentage from the wrist. Samsung’s sleep monitoring received FDA clearance for detecting sleep apnea, which is uncommon at this price point. Energy Score pulls your sleep, activity, and heart rate together into a single number each morning, and the watch tracks over 100 different workout types.
