Sadly, the app is only for Windows 10. I installed it on my tablet and then spent an hour attempting to pair my vivofit, because of course, why would it work the first time?
Once I got the device paired and my profile loaded, I could view “snapshots” of my categories. The app is very beautifully made, but I can’t see a “sync” button, and the Garmin article does not indicate whether the sync takes place automatically when the Bluetooth is on. My data synced when pairing the device, but I’m not sure if that’s just because of the initial pairing process.
While I am happy about this development (mainly because I have not been able to sync the vivofit for 6 days via the dongle on Windows 7), I don’t know if it’s enough to carry on using the Vivofit.
