01
Settle within a week
Memories fade faster than debts. Squaring up while the trip is fresh keeps it light – and nobody has to remind anyone.
Settle up
Good trip. Now who owes whom?
One paid for the flat, one for the groceries, one for dinner. Add who paid what and get the fewest transfers to make it even – no app needed for the others.

Stay friends
Money between friends works best when it's boring.
02
Write it down along the way
Add each payment on the day, with a photo of the receipt if handy. Reconstructing a week of spending afterwards is where arguments start.
03
Agree on rounding
Round to the nearest euro, or let small differences go. Chasing 37 cents costs more goodwill than it's worth.
04
Split by what people used
Not everyone drinks, drives or joins every dinner. Only split what someone actually took part in – that's what the "for" names are for.
Lent, borrowed, paid back.
Money Koi keeps track of what friends and family owe – and what's owed to them – with reminders, but without awkward conversations.
