Split Trip Expenses with Friends

Track every expense on your group trip in one shared Circle. See who paid, who owes, and settle up with the fewest transfers possible—no spreadsheets required.

How Circles work

Four steps from first coffee to final settlement.

1

Create a Circle

Name your trip, set a currency, and you're ready to go. Circles keep every expense organized in one place.

2

Invite your group

Add friends by username or share a link. Everyone joins the same Circle and can log expenses instantly.

3

Log expenses as they happen

Paid for dinner? Grabbed the Uber? Drop it into the Circle. Choose who it covers and how to split it.

4

Auto-settle at the end

When the trip wraps, nudj calculates the minimum number of transfers to square everyone up.

The balance matrix

Everyone in the Circle can see the live who-owes-whom grid at any time. No guessing, no side conversations, no forgetting.
