What problem does it solve?
The trip is over and the costs are spread across a group chat, someone's notes app and four people's memories. Whoever paid the big bills waits to be paid back. When the group finally settles, people send each other money that could simply have cancelled out.
How the demo handles it
Split records every amount in whole cents and checks that each split adds up to its expense. It nets the group's balances and reduces them to the fewest payments. The full who-owes-whom list sits beside the short payment list, so anyone can follow how it was worked out.
Duplicate check
When two people both add the same taxi, Split asks which one is real. It never merges them on its own.
More than one currency
Each expense keeps the exchange rate from the day it was entered, so an old total never moves when the rate does.
Private receipts
Receipt photos are visible to the group only, through links that expire.
