Every group trip has the same plot. One person puts most of it on their card, everyone says "just send me what I owe," and a week later it is a half-finished spreadsheet and an awkward group chat.
One organizer, one phone
Ledgr keeps the whole thing on the organizer’s phone. You add everyone’s names, log each expense as it happens, split it evenly or by hand, and it continuously works out the smallest set of payments that settles everyone up.
Nobody else has to download anything or make an account; they are just names you add. At the end you share one clean per-person summary.
It works on a plane, in a tunnel, or anywhere with no signal, because everything stays on your device.
