Muster Up: Group Trip Split

Pay once, own it: no ads, no subscription. Plan the food, share the shopping, track every cost and settle the group up with the fewest payments.

The whole group trip, sorted in one app.

Muster Up plans the food, shares out the shopping, tracks every cost and squares everyone up at the end — so nobody plays banker and nobody gets stung.

PLAN THE TRIP • Real locations from Apple Maps — one tap for driving directions to camp • Weather forecast for your spot as the dates get close (kept offline once loaded) • Multi-stop trips, each stop with its own nights • Save your group once, add everyone to the next trip in one tap

SHARE THE WORK • Invite the group with a link — Messages, WhatsApp, email, anywhere • Everyone sees the same trip and can add costs and tick off shopping • A shopping list built from everyone's appetite, and a pack list so you don't end up with four stoves and no tent • Drag any item onto a friend to make it theirs

SPLIT IT FAIRLY • Track costs as you pay, receipt photos attached • Split evenly, per person or per party, or pick exactly who shares what • Kids covered by a parent, guests covered by the group — the maths just works • Part-trip friends only pay for the nights they're there

SETTLE UP • The fewest payments that square everyone up, worked out for you • Mark payments made, attach transfer receipts • Export a PDF summary or spreadsheet for the group chat

PAY ONCE, OWN IT • One purchase. No ads, no subscription, no limits, no upsells • Your data syncs through your own iCloud — no accounts, no servers of ours • Works fully offline; everything catches up when you're back in reception

Works on iPhone and iPad.
