PayDas: split shared costs with friends

A trip, a camping weekend, a holiday or a dinner out. One pays for fuel, another for groceries, someone else for the campsite; a few days later nobody can untangle who owes what. PayDas tracks expenses day by day and shows who pays whom with the fewest transfers.

scheduleComing soon to Google Play. An iOS version is planned.

groups

One crew, many meet-ups

Create your friend group once. Football, a birthday dinner, the summer camp: each meet-up is its own event inside the group.

person_add

No app needed for everyone

Add friends by name; anyone can join later with a 6-digit code.

calendar_month

Day by day, only who was there

Someone joined on day two? Only the people present share that day's costs. Split equally, by shares or by amounts.

savings

Shared kitty

Everyone puts money in, shared costs are paid from the kitty. What's left and who put in what is always clear.

currency_exchange

Easy abroad

Enter costs in euros, dollars or any currency; they're converted at the rate you set, with your last rate suggested.

handshake

Settle with the fewest transfers

Close one event or all of the group's open balances at once. Copy the IBAN, mark it paid, share the list.
