How Duo works

Built for two people
and one pile of money.

Spending is shared — no “who paid this”. Deposits stay yours. The math just works, automatically.

One shared balance

Both of you see the same live number. Card spending is shared, with no awkward “who paid” tally to settle.

Your split, your rules

Every deposit is attributed to whoever earned it. Choose any split — even, income-based, or one of you covering more — and Duo keeps you on track.

Even, 60/40, or custom — your call

Trips that fund themselves

Set a goal, switch on auto-save, and watch the bar fill. Whatever you’re under budget rolls into savings.

However you split it

Your money, split
the way you want.

One account means shared spending — so Duo doesn’t split bills, it balances deposits toward whatever target you choose. Even, income-based, or one of you covering more for a while. You set the dynamic; Duo adapts.

Set any split. 50/50, 60/40, proportional to income — change it any time and Duo recalculates.
Spending stays shared. No “you owe me”. The debit card is just… the card.
Even up in one tap. Drift from your target and Duo moves just the difference.

This season, you’re covering a little more — so Duo aims for 60/40 and nudges only when you drift.
