Muster

Plan casual get-togethers and recurring group activities — and make it easy to see who's in.

iOS

What it does

Lightweight invitations — create a muster for your next ride, session, or pickup game in seconds
Quick participation signals — everyone taps in or out, so you can see at a glance who’s coming
Recurring meetups — set up weekly rides, Tuesday night skate sessions, or Sunday pickup without re-creating the event every time
No calendar bloat — sits outside your work calendar where casual plans belong

Made for real-world crews

Muster is built for the kinds of plans that usually happen in a group chat — the ones where half the coordination is just figuring out who’s actually showing up. It replaces the “who’s in?” thread with something everyone can see.
