hissa
photograph a bill, tap what you ate, everyone sees their share.
hissa (Urdu, حصه) — share, portion. what's yours out of what everyone had.
the problem
eight people, one bill, one person squinting at a receipt doing arithmetic while the food goes cold. someone had the biryani, someone had a salad, someone only had chai, and everyone ends up paying the same because working out the truth takes longer than it's worth.
splitting evenly is a tax on whoever ordered least.
how it goes
-
1 · snap it
point at the receipt. the lines and the tax fill themselves in. you check them — one wrong digit is a real argument later, so hissa always asks.
-
2 · pass the code
four letters. read them across the table or send the link. no account, no install, nobody downloads anything.
-
3 · everyone taps
tap what you ate. shared a plate? tap it twice. your number sits at the bottom of the screen and updates as people go.
what it does about the awkward bits
claims are portions, not people. a dish for two takes two taps and costs you two shares of it.
gst, discount and tip ride along proportionally. you never pay tip on someone else's steak.
every line is distributed to the last paisa. the group can't under-cover a bill by accident.
the naan nobody admits to. flip share leftovers and it splits across everyone who ate.
a settings screen, a profile, an onboarding carousel
— not building those.
honest limits
it's read by a vision model and thrown away. never stored.
anyone holding it can see the split. it stops working after a day.
hissa tells you the number. moving the money is between you.
