I'm interested why Garmin hasn't done this yet. A $400+ fitness watch that can't do simple oauth/API is a real concern of mine with buying any of their future products. I love the Garmin connect app but for it to be this limiting is going to make me find a product that supports Google Fit in the future. I've had some other issues with the watch and it's all starting to add up, the buyers remorse is starting to get bad...
