You run the night. The app keeps track of the queue.
See beforehand who is coming and with which instrument. In the room you call up the next group with one tap, and their phones let them know.
Before the night
- Sign-ups per instrument
Six signed up, no drummer yet: you'll see that by the afternoon.
- Asking the band if they are coming
One tap, and your regular line-up gets a notification.
- Inviting a house band
Or a guest for one night, by email or with a link. You see who's coming.
- Getting an opening set suggested
Five songs from the archive that suit who is coming, with help from AI.
- Setting the level
So musicians know what kind of night it will be.
In the room
- Who has checked in
Name and instrument, as soon as someone scans the poster.
- The queue with songs and keys
Musicians suggest songs. You say ‘Add it’ or ‘No’.
- Calling up the next group with one tap
Their phone says: Come to the stage.
- A message to the room
Tune your instrument, short break, last round.
- Handing over the night
Want to play yourself? Someone in the room can take over.
One tap, and the room knows
You tap ‘Switch to the next one’. The group for the next song gets a heads-up on their phones right away, and you see who is coming.
- Come to the stage, their phone says, with the song.
- On my way, they tap back. You see it straight away.
- Someone didn't answer? Call again, with one tap.

What hosts ask
Do I have to look at my phone all night?
One tap per song is enough. ‘Switch to the next one’ thanks the group on stage and calls up the next. Someone didn't answer? Call them again with one tap.
What if an instrument is missing?
Then that spot shows as ‘open’ in the list. Put someone from the room on it, or ask the room for someone.
Can I still change the order?
Yes, with ‘This one first’ or ‘Later’, or by dragging. Musicians suggest songs with their key, and you say ‘Add it’ or ‘No’.
I want to play too. Can someone take over?
Hand over the night to someone in the room. They have five minutes to say yes, and you can withdraw the request.
Does everyone need the app?
Anyone who wants to play does: that is how they check in and hear when it's their turn. Anyone who only comes to listen does not need it.
What does it cost?
Nothing. The app is free, for hosts too.
