Your household money, finally aligned.

From payday scramble to five minutes.

The maths runs across both incomes and every joint obligation. You get a checklist.

• Exactly what to send, to the penny

  One amount for each account. Tap an amount to copy it into your banking app, and you're done.
• Your personal allowance is protected

  Once the joint transfers are done, whatever’s left in your personal account is yours to spend. No oversight, no guilt.

One household. Two people. One agreed plan.

• Both incomes

  See the household picture across both partners, not just your own accounts.
• Shared decisions

  Changes to a shared target need approval from both partners before they take effect.
• Personal money stays personal

  Once your household commitments are covered, what’s left in your own account is yours.

No one changes the household plan alone.

Any tweak to a shared target needs a tap from both phones before it takes effect.

• Request sent

  One partner proposes a change — say, increasing the holiday fund target.
• Partner reviews

  The other partner sees exactly what’s changing, and why.
• Plan updates

  Only once both agree does the shared plan actually change.

Your money should be shared by agreement, not changed by surprise.

Every account, card and bill. One place.

Stop opening four banking apps to work out what the household actually has left this month.

• Add it by hand, or upload a statement

  Type in your balances yourself, or drop in a PDF or CSV export from Monzo, Starling, Barclays, Lloyds, HSBC and more — Duolign reads the transactions straight off it, no bank login required. Your data stays entirely under your control.
• Shared the moment it’s in

  Enter it or upload it once, and you’re both looking at the exact same numbers — no more texting screenshots back and forth.
• One number that matters

  What’s genuinely left across everything — not four balances you have to add up in your head.

See where the money’s taking you, not just where it went.

Duolign models the months ahead so a decision made today has a number attached to it.

• Surplus routed to your priorities

  Once the bills and baselines are covered, the household surplus goes where you both agreed — paying down debt, or savings towards a deposit, a wedding, next year’s holiday.
• Avalanche and Snowball, side by side Premium

  Avalanche saves the most interest; Snowball clears balances fastest. Duolign shows the exact month you’re debt-free on either plan.
• A forecast five years ahead Premium

  See where your savings and debts are heading, in an expected, a cautious and a stress view. Then ask it: what if one of us loses our income, earns more, or we save for a deposit? Every answer shows how it was worked out, and nothing you try touches your real plan.
• A health check, not a score

  Six areas, from cash flow to how long your savings would last, each with a status and the figure behind it. Where Duolign doesn’t know enough, it says so rather than guessing.
