Remote Gear lets you control your Roku from your Samsung smartwatch! It connects your Roku and smartwatch through your mobile device. It consists of two parts - the phone app and the smartwatch app. In the phone app you can select which Roku device you want to control. You can control your Roku from both apps.

To make sure the watch app works when the phone is off, please turn off battery optimization for "Samsung Accessory Service" and "Remote Gear for Roku" apps under Android Settings > Battery Optimization.
