untilt splits bills with friends, flatmates and travel groups — without an account, and without handing your spending history to anyone.

Add everyone by name, share one link or QR code, and start splitting straight away. People who haven't joined yet can still be in the group: they claim their name when they open the invite.

WORKS OFFLINE, ALWAYS
Every change saves to your phone the moment you make it — on a plane, in a basement restaurant, on a foreign SIM with no data. It syncs when you're back online, and the app shows you honestly what hasn't gone out yet.

NO ACCOUNT, NO EMAIL, NO PASSWORD
There is nothing to sign up for. Your identity is a name, a colour, and a key created on your phone, and that key is never sent to our servers. Reinstalling on the same phone usually brings it back on its own. To move to a new phone, export a recovery code and keep it somewhere safe — it brings your identity across, and your active groups sync back onto the new phone.

PRIVATE BY DESIGN
Your bills are end-to-end encrypted. Names, amounts, notes and comments reach the sync server only as scrambled data it cannot read, and the key that unlocks them travels only inside the part of an invite link that browsers never send to a server. No analytics, no tracking, no ads. We have no way to see what you spend, and nothing to sell.

SPLIT IT HOWEVER IT ACTUALLY HAPPENED
• Equally, by exact amounts, by shares, or item by item
• More than one person paid? Record all of them
• Emoji categories, so the feed is scannable at a glance
• Drag to reorder the feed
• Leave a comment on any expense — a note for whoever still owes their share

SCAN THE RECEIPT
Point the camera at a receipt and untilt reads the line items on the device itself — the photo is never uploaded. Tick off who had what, and the tip and total are split proportionally.

MULTI-CURRENCY THAT DOESN'T DRIFT
Paid in a currency that isn't the group's? untilt converts it and locks the rate into the expense the moment you enter it, so the numbers don't quietly change later. Amounts always display in their own currency's convention, so they look identical on everyone's phone.

SETTLE UP WITH FEWER TRANSFERS
Balances simplify into the smallest number of payments, or switch to Everyone for the full picture. untilt records who paid whom — it doesn't move money.

SEE WHERE IT WENT
Totals by category, by person, and over time.

NOTHING IS STUCK
Fix or delete any expense or payment. A full activity log keeps the history, and if two people edit the same thing you're told about it rather than quietly losing your version. Export your expenses and payments to CSV whenever you like, and bring a group back the same way on a new phone.
