If you have a Samsung watch on Tizen OS, you can already download our watch app using the Galaxy Wearable (Samsung Gear) app available from Google Play: https://play.google.com/store/apps/details?id=com.samsung.android.app.watchmanager&hl=en&gl=US. If your watch is on WearOS, we haven't released the respective app yet as we've been in the process of developing to support WearOS-based devices. The release is planned — it's in the final testing stage, i.e. the new version with the watch app will be available in Google Play soon. Please stay tuned for the update!
