How to Choose a Smartwatch or Fitness Tracker
- Match the watch to your phone. Apple Watch works only with iPhone, and current Galaxy Watches work only with Android phones. Garmin, Fitbit and Amazfit work with both.
- Check GPS if you run or ride. Built-in GPS, like on the Fitbit Charge 6, Garmin Forerunners and Amazfit Bip 6, tracks pace and distance without carrying your phone. The Inspire 3 borrows your phone’s GPS.
- Think about battery life. Apple and Samsung watches usually need charging every day or two, while the Garmin, Fitbit and Amazfit picks here last a week or more.
- Watch the clock on October 7. Prime Big Deal Days ends at 11:59 p.m. PT on October 7. If something you want isn’t discounted, look again around Black Friday on November 27.
