The Roku app lets you turn your apple smartwatch into a remote. It allows you to launch various Roku-based channels, control the cursor on your TV interface, play and pause your videos.
The Roku app also lets you use voice control, allowing you launch channels or find programs without having to tap your screen just as long as you are using an Apple Watch Series 1 through 5. So far it doesn’t work on the first-generation watch.
The app can also make the remote chime and help you easily find it, if you would prefer to use the remote. The new Roku app for the Apple Watch can be installed from the updated iPhone app, version 6.1.3 and according to Roku, you may need to manually install from the Watch app if automatic installs are turned off.
