The money app built for two — see everything, plan together, stay in sync.
Most money apps are built for one person, then stretched to fit two.
Duet was built for two from the very first line.
The gap
Between the two of you there are accounts in different places, bills on different days, and a running tally that lives in someone's head. The hardest part was never the maths — it's the not-knowing, and the conversations you keep meaning to have.
Duet closes that gap, so you can spend less energy managing money and more on the life it's for.
What's inside
Every account in one view — without chasing statements or comparing notes. The full picture, finally in one place.
Decide together how bills, savings, and spending are split, and let Duet keep the running total. Same numbers for both of you — nothing to reconcile, no one keeping score.
Set budgets you share, then watch them update as life happens. When you're in sync you'll know — and when you're drifting, early enough to talk about it calmly.
The house deposit. The trip. The "one day." Set a goal together and track it side by side, so it stays real for both of you — not just the one watching the balance.
See it in action
Everything in sync, what's safe to spend, and a fair split you both agreed on — at a glance, on your phone.
Your whole month, at a glance

To even up this cycle, Alex transfers Sam $240.

The biggest thing you share
It's the largest commitment most couples ever make — and the one a single-player money app handles worst. Duet tracks exactly who's paying it down, splits it the way that's fair for you, and shows what every extra dollar is really doing.
No more mental tallying. Duet attributes every repayment to each of you — by income, an even split, custom percentage, or a fixed amount. The number you've each contributed is always there, in black and white.
One partner earns more? Split by income. Want it even? One tap. Each property can be split its own way — and the rest of your budget stays in sync with whatever you choose.
Offset and redraw, attributed to each of you and turned into a real number: the interest you're saving and the years you're shaving off. Decisions you make together, with the upside in plain sight.
Secure by design
Duet connects through Australia's Consumer Data Right — the same open banking framework the major banks use. Your accounts link directly and stay current on their own. No spreadsheets, no passwords to hand over.
Duet can see your balances and transactions. It can never move, spend, or touch your money.
You connect through your bank's own secure consent process — never by giving us your login.
You choose what to connect, and you can disconnect any time.
Privacy by default
Some couples share everything. Plenty don't want to — and that's the point. You decide what your partner sees, one account at a time. Nothing is shared until you choose to share it.
Nothing. This account stays private.
"Every money app treats a couple like one person with a plus-one. Duet is built the other way round — for two, from the very first line. I'd love to have you with us early."
