Unfortunately, we do not have a native RokuTV app at this time.
You can mirror your screen to your RokuTV. First enable Screen Mirroring (set to 'Always Allow') in your Roku TV's settings.
On Windows 10:
-Click the Action Center button in the bottom right corner of your screen
-Select Connect - then choose your RokuTV
-Use the pulldown menu and select 'Screen Cast'. You should see your RokuTV listed.
-Once you have mirrored your screen to your TV use the nugs.net Android app and access your streams in the My Library>My Events section of the app.
On Mac or iOS:
On Newer Roku Devices you can use Airplay2 / Home Kit to stream the show directly from your iOS or Mac to your TV using Airplay. For more information see HERE
To mirror from Mac to Roku for free: download the RokuCast Chrome extension from THIS LINK and follow the instructions to install it and connect it to your Roku. Then use Chrome and cast your screen or video from your Mac to Roku
