FairThen started with one developer who got tired of fighting over the dinner bill. No investors to please, no dark patterns, just a tool that keeps things fair.
Everything you need to split fairly
Nothing you don’t. All of it free, with nothing to buy.
Groups, friends, and people who never install it
Make a group for the trip or the flat, keep a one-to-one tab with a friend, and add guests who do not have the app at all.
Split any way that is fair
Equally, exact amounts, percentages, shares, or equal with adjustments. More than one person can pay, too.
Split by Item, tax and all
Build the receipt line by line, pick who is in on each item, and let service charge, tax, tips and discounts land where they should.
Scan the receipt, skip the typing
Point the camera at the bill and the items land in an itemized split, ready to assign.
One expense, several groups
Paid for something that touches the flat and the trip? Add it once and send it to every group and friend it belongs to.
Settle up in the fewest payments
Net balances, who owes whom, and an option to simplify the tangle. Each currency settles in its own lane, with no surprise conversions.
Works offline, syncs later
Add expenses on a plane or in a basement bar. It saves on your device instantly and catches up quietly when you are back.
A clear trail, with an undo
Every add, edit and removal is logged and filterable by date, person and group. Deleted the wrong thing? Restore it.
Three taps from chaos to fair
It really is this simple.
Make a group
One for the trip, the flat, the dinner crew. Invite people with a code.
Add an expense
Type it, or scan the receipt. Split equally, by item, or however’s fair.
Settle up
See who owes whom in the fewest payments, then square up in real life.
Bring your own AI
FairThen’s AI runs on a key you own. Paste one from Google AI Studio or Cloudflare Workers AI, both of which have a free tier, and Receipt scan goes straight from your phone to that provider, after the app asks you the first time. Nothing to buy from us, no quota, no bill from us. You’re their customer for those requests, so their terms apply, and it’s worth checking what the AI gives back before you rely on it.
How to get a keyPricing that won’t make you wince
