Split it fairly

The part of a group trip that ends friendships. Built so every figure can be traced back to the expenses that produced it.

Who paid and who shared are different questions
An expense records a payer and, separately, the people it is split across. You can pay for a taxi you were not in, and the ledger will still be right.
Four ways to split
Equally, by exact amounts, by shares, or by percentage. Shares are the one people reach for without knowing the name: two shares for the couple, one for the solo traveller.
Multi-currency, priced when it happened
Every expense carries its own currency, and the exchange rate is captured and stored on the expense at the moment it is entered — priced on the day the spending happened, and never quietly re-fetched afterwards. The rate is data, not a lookup. The payer can override it with what their card actually charged.
The cents add up
Splits are allocated so they sum exactly to the total, in the original currency and the converted one. Odd cents are assigned to someone. They are never invented and never lost.
Balances you can interrogate
A live net position per person, plus the smallest set of transfers that clears everyone. Behind every figure is a panel showing how it was reached, so the answer to "why do I owe that" is on the screen instead of in an argument.
Settling up, including partly
Record a payment between any two people for any amount, in any currency, and attach a screenshot as proof. A loan is its own kind of record — money lent between two people is not an expense the group shares.
A common fund, if that is how your group works
Pool money up front and pay for things out of the pot, with a live pool balance and a close-out that returns what is left pro rata and still sums to zero. The kitty exists because it is how group trips in the Philippines are actually organised, not because a split-the-bill app needed another feature.
A budget, kept out of the ledger
An overall trip budget and per-category ceilings, measured against real spending — deliberately separate from what anyone owes anyone.
Scan to pay, without Layag in the middle
Publish your own GCash or Maya receive-money QR so whoever owes you can scan instead of retyping an account number. The transfer happens in their banking app.
