With Tappla, you can build native SDK apps for Roku and Apple TV.

You don't have to code or worry about app design - we have a ready-to-use template that looks like Netflix.

All you have to do is connect/integrate your videos and we take care of the rest.

Our Roku SDK grid screen template

Here is an example of what your Roku SDK Channel might look like:

Grid Screen Template:

Videos in a playlist appear side by side in the same row, and additional playlists appear below in a new row.

Launch Behavior:

When the user clicks on a video thumbnail, the video expands to full screen and begins playing immediately.

Dynamic Background:

The background image changes dynamically. It is always the thumbnail of the selected video.

What we need from you to publish your Roku SDK app:

  1. Invite us to Roku Developer (email: [email protected]) at: Roku Developer Access.

  2. Tell us the name of your Roku Channel.

  3. Send us your Roku app images. We recommend using your logo with a simple background for all images to keep the design clean and professional.

Required Images:

  • Splash Screens: These appear briefly when your Roku channel starts and are the first thing viewers see while your video content loads. Required sizes:

    • Full HD: 1920x1080px (JPG)

    • HD: 1280x720px (JPG)

    • SD: 720x480px (JPG)

  • App Icon: Displayed as the app icon on the Roku home screen and in the Channel Store listing. Required sizes:

    • Focus HD: 290x218px (JPG)

    • Focus SG: 246x140px (JPG)

  • Logo: Displayed inside your app at the top. Required size:

    • 290x218px (PNG)

We will use your provided images as-is, but if you need recommendations, we suggest using a dark background color with your logo to maintain a clean, professional look.
