About
Haan Harn — split bills with friends, without the math.
Haan Harn is a group expense app for trips, parties, and anything you share the cost of. Create a group, invite friends, add bills, and let the app work out who owes what.
What you can do
Groups and invites
Invite friends with a code, or sign in instantly with LINE.
Bills organized by event
Keep bills under the trip or activity they belong to, and pick who joins each event.
Equal or itemized splits
Split a short bill equally, or itemize exactly who shared which dish.
Settle up easily
See who has paid, who still owes, and by how much.
Why Haan Harn
Every trip ends the same way: a pile of receipts and a calculator. Haan Harn shrinks that job to jotting bills as you go — the app settles the totals at the end.
It is designed to be usable right away without an account, and syncs across devices once you sign in.
