Bring harmony to your finances

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.

Two incomes, three accounts, and one person quietly running the spreadsheet. Sound familiar?

What's inside

One clear picture, for the two of you

Every account in one view, a split you both agreed on, and the same numbers on both phones. Built for two, not one with a guest.

Duet Budgets screen: safe to spend for the couple, with what is left for Joint, Alex and Sam

A plan you both agree on

Safe-to-spend up top, then who covers what. Catch the drift early enough to talk about it calmly.

Duet Goals screen: what the couple has saved together, and how much each partner has put into shared goals

Point at the same future

The house deposit. The trip. The "one day." Goals split between you, plus set-asides for the bills you know are coming.

Duet Fairness screen: each partner's contributions this month against their agreed split

No one keeping score

Who actually paid versus your agreed split, and the one transfer that evens it up.

The biggest thing you share

Finally, a finance app that handles the mortgage the way you do

It's the largest commitment most couples ever make, and the one a single-player money app handles worst.

See who's actually paying it down

No more mental tallying. Duet attributes every repayment to each of you, so what you've each put in is always there, in black and white.

Split it the way that's fair for you

One partner earns more? Split by income. Want it even? One tap. Or a custom percentage, or a fixed amount. Each property can be split its own way, and your budget follows.

Know what every extra dollar does

Offset and redraw, attributed to each of you and turned into real numbers: the interest you're saving and the years you're shaving off.

For the family chapter

Plan the leap into parenthood side by side

Any app can draw you a pie chart of last month. We built Duet for the harder question: how do two incomes become one for a while, then climb back to two?

Map the leave window together

Try a few plans for who takes leave and for how long, and compare how each one plays out, month by month, so the first smaller pay packet never catches you out.

Is the extra day worth it?

Childcare and tax can swallow a surprising slice of a second income. See what three, four or five days a week actually puts in your pocket once those costs come out.

Plan before you tell anyone

Start the day you find out. None of it shows on your dashboard, in a notification, or anywhere else in Duet. It stays between the two of you.

Secure by design

Connect your accounts in minutes. Securely.

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.

Read-only by design

Duet can see your balances and transactions. It can never move, spend, or touch your money.

No password sharing

You connect through your bank's own secure consent process, never by giving us your login.

You're in control

You choose what to connect, and you can disconnect any time.

Privacy by default

Private by default. Shared by choice.

Some couples share everything. Plenty don't, and that's the point. You decide what your partner sees, one account at a time.

Who can see this account?

AWhat Alex sees

Nothing. This account stays private.
