One shared ledger for two parents, so nobody has to remember who paid for what.

Halves is in beta. Everything is free while it is, with no card and no trial clock.

Both of you see it

Every expense and payment is attributed, and nothing is ever deleted.

Agree or dispute

The other parent acknowledges an expense, or disputes it with a reason.

Split it your way

Shares apply from a date you set, so changing them never rewrites history.
