The S Fitness App tracks my heart rate and distance while riding, and allows me to send texts or make calls without being tethered to the Samsung mobile device, a nice feature to have when the weight of a smart phone is unwelcome in my running or cycling pack

It comes in Korean and does not pair with many smart phones

I'm still trying to find a watch that is compatible with my Samsung grand prime phone

However it wasn't compatible with my Samsung grand prime phone

Make sure you have a compatible phone as that is critical.

The other drawback is that while you can send texts from your Gear S without your phone being there it will text from the Gear S number not your phone's number

Can't connect to non Samsung phone... even some Samsung phone is compatible with this watch

but I gave it to my finance as a gift because it work very well with his samsung note 2 phone
