One thing all of the best Garmin watches have in common is that each one syncs with the Garmin Connect app — the place where you can keep track of your progress, view your runs and bike rides, and dig deep into your sleep data. Garmin Connect is available on your smartphone as a free app (Android (opens in new tab), iOS (opens in new tab)) or as a web service (opens in new tab). No matter where you access Garmin Connect, it’s easy to use and it comes with a number of handy features and tools to help you become a better runner.
