In Mello United (works only on tablets), you can watch live broadcasts of the Melodifestivalen and other Mello-related content while sending messages to your friends in your various friend groups. During the competitions, you can also react to the entries and vote for your favorites for free.

To vote, click or tap the heart in the app so that it grows. A full-sized heart equals one voice. In the live broadcast, the heart in the box shows how much is being voted for right now. You can comfort your heart up to five times on each contribution.

The app follows the same regulations as the TV program follows for voting and therefore you can only vote if you are in Sweden.
