1 · Create a tab
Name it after the trip, the dinner, or the flat. You get one short link.
Split the bill. Keep the friendship.
Create a tab, add who's paying what, and share one link. No passwords, no apps to install — just the math, done cleanly, and a settle-up plan that closes the books in the fewest transfers.
2 · Add people
Everyone joins by name — no passwords, no accounts to babysit.
3 · Log expenses
Who paid, how much, split evenly or by custom shares.
4 · Settle up
See who owes what and close the books with a few transfers.
