Any health nuts out there use a smartwatch specifically for fitness and use it with google health? I don't mean the traditional smartwatches like Huawei and LG, but the more fitness oriented ones from Garmin, Polar, etc. But I have no idea how they store workouts, do they have proprietary apps or do they connect to an Android phone and upload information to Google health? I'd MUCH prefer to have a centralized location for my health data like google health. Money is no object, I just want the best of the best. Main concerns are a decent heartrate monitor.
