How to choose
- iPhone Compatibility. Ensure the tracker works with iOS and the Apple Health app for seamless data sharing. Most modern trackers, such as Fitbit and Garmin, offer full iOS support.
- Battery Life. Consider how often you want to charge. Trackers like the Garmin Venu Sq 2 last up to 11 days, while the Apple Watch requires daily charging. Choose based on your lifestyle.
- GPS and Accuracy. Built-in GPS is essential for outdoor runs without your phone. The Fitbit Charge 6 and Garmin Venu Sq 2 have it, while the Fitbit Charge 6 Fitness Tracker relies on phone GPS.
