After testing more than a dozen waterproof fitness trackers, we recommend the Garmin Swim watch as the best overall wearable device for swimmers. If you're looking for a GPS watch that can track swimming both in the pool and in open water, we recommend the Suunto Ambit3 Sport GPS watch. But if you need a wearable device that tracks workouts in the water and on land, we recommend the Moov smart fitness coach and tracker.
For our roundup of the best wearable devices for swimmers, we tested 16 fitness trackers, GPS watches and smartwatches in the pool. We wore them while swimming laps, treading water, jogging underwater in the pool's shallow end and doing resistance exercises with a kickboard. Then, we evaluated each tracker based on its comfort, design, accuracy, user-friendliness and the value of information it provided. Here are our top picks:
Best Swim Tracker Overall: Garmin Swim
Compatibility: Garmin Connect mobile app...
