Less admin.
More game.
Jum turns "who's in this week?" from a scroll through your group chat into one tap. RSVP, teams, expenses and who-owes-who — all in the app your group already has open, not spread across a chat log and a spreadsheet.

What is Jum?
The app for running your community's recurring game.
Jum is a mobile app for organising community sports and social events. An organiser posts an event, members RSVP, Jum splits the group into teams, and after the game it tracks who paid for what and who still owes whom — so the group chat can go back to being a group chat.
The problem
Every week, the same questions get asked all over again.
A WhatsApp group is a chat log, not a system of record. Nothing in it actually keeps score.
"Who's actually coming?"
"Who's on which team?"
"Who paid — and who still owes?"
"What happened last time?"
Before the game → after the game
How Jum works, one game at a time.
The same loop your group already runs — just with nothing to remember and nobody to chase.

What's inside
Everything a weekly game actually needs.
Events & RSVP
Post the date, time and venue once. Members RSVP with a tap, and you see who's in — and who's on the waitlist — in real time.
Team formation
Auto-assign balanced teams from who's actually going, adjust manually, then publish the roster for everyone to see.
Expenses
Whoever paid for the pitch or the drinks logs it in seconds. The organiser approves, and the cost is already split.
Settlement & ledger
Everyone can see exactly what they owe or are owed — and mark it paid, no more "did you get my transfer?"
Community & roles
Run more than one group from one account. Admins organise, members RSVP and invite, guests join a single game.
Notifications
A nudge when the waitlist opens up, when teams are published, or when it's time to settle — not another group ping.
Why people use Jum
Nobody wants to be the group's accountant.
One person usually ends up carrying the whole system in their head — the list, the teams, the money. Jum carries it instead.
No more chasing
RSVP and settlement happen in the app, not in fifty separate messages.
Fair teams, every time
Teams are drawn from who's confirmed going — not who shouted first.
Money, sorted transparently
Everyone can see the split. Nobody's guessing what they owe.
A real history
Every past game, who came, and what it cost — not buried in chat scrollback.
Who Jum is for
Any group that plays on a schedule.
Jum isn't built around one sport — it's built around the pattern: the same people, showing up regularly, splitting costs.
Built for communities
One app for every group you run.
Jum isn't scoped to a single game. Create a community for your Thursday futsal crew, another for your Sunday running group — each with its own members, events and ledger, all under one account.
Public communities are discoverable by anyone nearby looking for a game; private ones stay invite-only.
Share a link, not a headache
Invite by link, let people request to join, or keep it fully private. Guests can join a single event without ever creating an account.
Ready to Jum?
Jum is in private testing with real communities right now, ahead of a public launch on iOS and Android. Store links go live here the moment they're ready.
