Even - Split Expenses

Split costs with friends on a trip, in a house, or over dinner. Add what you paid, split it equally, by amount or by percent, see who owes whom, and settle up. No accounts. No sign-up, no email, no password. A group is a link: share it, or show its QR code, and anyone who has it is in. Private by construction. Amounts, titles, notes, names and the group's name are encrypted on your phone before anything is sent, with a key that exists only in the invite and on the phones in the group. The sync server passes them between phones and has no way to read them. Works offline. Every phone keeps the whole history, so you can add expenses with no signal and they sync later. Run your own server. The sync protocol is public and the server is small. Point a group at a server you run, and nothing about it goes through ours. Free and open source, made by Appalaya Inc. No ads, and nothing to buy.
