Everything in Harmny sits behind four tabs and one button along the bottom of the screen.
Rehearse
Your home screen. It shows your next rehearsal, the songs for it and a note from your conductor if there is one. Tap a song to play it.
Library
Everything you own, in three sections: Songs, Playlists and Downloads. Add your own songs here.
The round amber button
The button in the middle plays and pauses from any screen. If nothing is loaded, it plays your part from the next rehearsal's songs, or your own songs if there's no rehearsal yet. A ring around it fills as the song plays.
Choir
Your choirs, their rehearsals and members, and practice rooms for singing along together.
Me
Your voice part, rehearsal emails, appearance (light or dark), your plan and billing.
On a computer, the same sections run down the left-hand side instead.
