Split bills, not friendships
Splitter is a native SwiftUI app for Mac and iPhone that tracks shared expenses in a group, works out who owes whom to the cent, and suggests the shortest list of transfers to settle up.
Why it makes the list
It's genuinely native — one SwiftUI codebase for Mac and iPhone, synced live through Supabase, with no web views and no "sync now" button. Friends without an account can still be added to a split by name.

Balances, not totals — a live balance card and a "who pays whom" view with the fewest transfers to settle up

-
29 languages, with per-group currencies
