Smartwatches like the Galaxy watch or Apple watch collect the same data as smartphones. This includes general usage and crashes data while controlling smartphone functionality and communications. Health tracking is one of the more popular features apart from the internet browser. Smartwatches use sensors in their displays or attached devices to collect information about how you move (steps) and track other metrics like heart rate and calories burned. Some smartwatches use this information to display notifications from your phone when you're away from it.
