🏃 Fitness Bands & Trackers

If you find wide, heavy smartwatch cases uncomfortable to wear in bed or during high-rep gym and yoga sessions, a dedicated fitness band delivers the health metrics you actually care about at a fraction of the weight and price. Modern fitness trackers weigh under 25 grams including the strap, offer 5ATM swim-proof water resistance for pool lap tracking, and run for 10 to 14 days between charges so you never miss overnight REM/deep sleep staging, heart-rate variability (HRV), and resting heart-rate recovery trends. Here we compare photoplethysmography (PPG) sensor accuracy during interval training, companion app data export and privacy, paywalled features (such as Fitbit Premium versus subscription-free Mi Fitness, Zepp, and Huawei Health), and breathable TPU or braided nylon strap durability.
