Money shared between people, on a server of your own
Tally is for a trip, a flat or a dinner club: who paid, who owes whom. It is being built, and runs on a server you chose.
What you write is sealed
The names and words of your groups are sealed in your browser, so only their members can read them, and the server cannot.
Signing in
A password, a passkey or an authenticator app. The one you sign in with also unlocks a new device: no key to keep.
On a phone or a desktop
The same places at the same addresses at every width, in light or dark.
