HOW IT WORKS

Four steps. No awkward maths.

  1. 01

    Photograph the receipt

    Take one photo or several for a long receipt. Straighten the edges before you send it, or save it offline and let it upload later.

  2. 02

    Check what was read

    cost-share reads every line and checks the sum against the printed total. Review the photo and edit anything that needs attention.

  3. 03

    Choose who had what

    Assign each item to one person or share it equally, by quantity, or with your own proportions.

  4. 04

    Settle the balance

    See exactly who owes whom. cost-share combines every receipt into the fewest payments and keeps track as you settle up.

EVERYTHING YOU NEED

Made for the way group spending really works.

Messy receipts, different currencies, uneven shares and friends who have not signed up yet: all handled.

Receipts without the typing

Built for real paper receipts, not just neat screenshots.

  • Join several photos into one long receipt
  • Read items, quantities, discounts and totals
  • Check that every line adds up to the printed total
  • Capture offline and upload when you reconnect

Easy to review and correct

Automation does the first pass; you stay in control of the result.

  • Tap a line to find it on the original photo
  • Edit descriptions, quantities and prices
  • Translate unfamiliar item names
  • Ask AI to repair a receipt that does not add up

A fair split for any group

Useful for a household, a holiday, or one big shopping trip.

  • Split items equally, by count, or by custom weights
  • Invite people with a link when they are ready
  • Add someone before they create an account
  • Reuse the previous split or assign the rest to everyone

Clear balances, all in one place

The maths stays visible, down to the last cent.

  • Convert foreign receipts into the group currency
  • Reduce the final balance to the fewest payments
  • Record payments and see what is still outstanding
  • Export the event as a CSV whenever you need it

One receipt. Everyone’s fair share.

Create a group for your home, your trip, or just tonight’s shop. Add the first receipt and let cost-share do the arithmetic.
