About
No email. No password. Just a name, a link, and you're splitting expenses with your group.
kisir is for trips, flats, dinners and any group that shares costs. Create a group, send the link or QR code, and everyone's in — nobody signs up for anything.
SEE WHO OWES WHOM
Open a group and the Overview shows your balance first: who you owe, who owes you, and how much each person has spent. kisir works out the fewest payments that settle the whole group, so it's never everyone paying everyone.
SPLIT IT YOUR WAY
• Split equally, by shares, or by exact amounts
• More than one payer on the same bill
• Only the people it was for — not the whole group by default
• Add someone who doesn't have the app; they're still in every split
ANY CURRENCY
Paid in pounds on a trip in euros? Enter what you paid and kisir fills in today's exchange rate. Change it if your bank charged something else.
SETTLE UP IN ONE TAP
Tap = to record what you've sent. When everyone is square, the group closes itself — and re-opens if someone adds another expense.
NEW IN 1.1
• Works offline — add and edit expenses anywhere, they sync when you're back online
• History on every expense: who changed what, and when
• Notifications when someone adds an expense, pays you, or changes one you're on
• Filters: All, Paid by me, For me
• Opens instantly on your saved data
