How to choose

- Sensor Accuracy. Look for optical heart rate, SpO2, and GPS. Higher-end models from Garmin and Fitbit offer the most accurate sensors for running and sleep tracking.
- Screen Type and Size. AMOLED displays offer vibrant colors but drain battery faster. If you prioritize battery life, consider a tracker with a transflective display like the Garmin Forerunner.
