Choosing a fitness tracker depends on several key criteria.  Battery life and sensor accuracy are among the most important. It’s also crucial to consider the tracker’s weight to ensure comfort and avoid discomfort while wearing it, especially at night.

Integrated technology plays a central role. Most models measure heart rate, step count, and blood oxygen levels. The most advanced versions connect to dedicated apps, allowing for detailed data tracking and personalized advice. Some bracelets can even send alerts to remind you to move or sleep at a specific time.
