Golfshot GPS is compatible with Android Wear devices only. Any device using an OS other than Android Wear is not compatible, for example Tizen by Samsung or any Fitbit. Here is a list of Android Wear devices: https://wearos.google.com/#find-your-watch
We may port Golfshot to other wearables in the future, it's on our list. Development for new platforms such as Tizen necessitates great research and time, we appreciate our community's requests and feedback on this matter. If you have a particular wear device in mind, let us know in the comments below.
