Roundsplits

Roundsplit is the round counter for groups at a bar.

Every other split app handles the wrong problem. They take a single
receipt at the end of the night and divide it up. But that's not how
people actually drink. You go out for the night, someone gets the first
round, someone else gets the second, the table grows, somebody sits out
the shots - by closing time nobody remembers who paid for what, and
"let's just call it even" leaves at least one person quietly resentful.

Roundsplit tracks rounds AS THEY HAPPEN.

Tap whoever just paid, type the cost, hit save. The app keeps a running
tally for every person: rounds bought, money paid out, share of rounds
received, and a live net of who's up and who's down. When the night
ends, hit Settle Up - Roundsplit gives you the fewest possible
transactions to zero everyone out.

WHAT MAKES IT WORK

• Per-night rosters. Someone arrives at 9? They're only in the rounds
from 9 onward. No retroactive math.

• Per-round opt-outs. Designated driver, late arrival, vegan night -
exclude anyone from a single round in two taps.

• Greedy settlement. The Settle Up screen finds the minimum-transactions
matrix. Four people, three transactions. Five people, four. No "Alex
pays Sam $4.32 and Sam pays Jamie $4.32" nonsense.

• Keep-screen-on toggle. The phone won't lock between rounds while
you're at the bar.

• Live "running tab" header that pours an amber fill as the tab climbs.

• Round history with timestamps, notes ("shots", "two pitchers"), and
the per-person split shown alongside the total.

• Edit or delete any round. Tap a round in history, change the payer,
the cost, who was in it.

• Re-open closed nights. Accidentally tapped End Night? It's not gone.

• Per-night currency override. Trip abroad? Set the night's symbol once.

WHAT IT IS NOT

Roundsplit does not move money. There is no Venmo, no Apple Cash, no
PayPal integration, no signup. It does the math. You handle the cash.

PRIVACY

Everything stays on the device. No accounts. No analytics. No cloud
sync. No third-party SDKs. Your nights live in this app's local storage
and disappear when you delete it. The privacy manifest declares only
UserDefaults access (used to persist nights and preferences).
