Volunteers aren't staff — you ask, you don't tell. So the rota goes out as a link, everyone answers from their phone, and you see who's confirmed and which shifts still need a body.
7 days free, no card. Then $29.99 a site per month — however many volunteers you have.
The week's shifts: green is covered, red still needs someone to say yes.
You pencil people in; they answer yes, maybe or no from their phone. With volunteers that answer is the whole game — a name on a rota isn't a person in the building.
Each volunteer gets a link to their own shifts. Nothing to install, no password to forget — it works for the seventeen-year-old and the seventy-year-old on whatever phone they've got.
A shift nobody's confirmed turns amber, then red. You find out the Saturday stall is short on Tuesday, while there's still a week to ask around.
Anything going short shows up for people who could take it. The keen ones put themselves forward — you just say yes.
Set the shifts you run — match days, opening hours, the Sunday service — once. Every rota after starts from them with one click.
The shop, the café, the visitor desk — a rota each, with its own people, from the same login.
