dupla - Couple's finances

dupla is the finance app for couples. One shared money life, seen through two completely personal apps: each of you has your own account, your own look and your own language, over the same shared ledger.

MINE AND OURS
Every expense goes on one of two lists. "Ours" shows up on both phones at once, already split. "Mine" never leaves yours. Privacy is symmetric: neither of you can see the other's personal spending.

SPLIT THE WAY YOU ACTUALLY DO
• Fifty-fifty
• By income, so each contributes in proportion to what they earn
• A fixed percentage you choose
• All shared: no debts, just tracking
For a one-off expense, change it on the spot: 50/50, all me, all my partner. dupla does the math and remembers how each expense was split.

A BALANCE THAT IS ALWAYS UP TO DATE
Who owes whom and how much, netted across everything you share. Settling up is one tap, and the history stays.

PESOS AND DOLLARS
Log each expense in the currency you paid in. The day's exchange rate is saved with it, so the balance doesn't move when the dollar does. Switch the whole app between ARS and USD with a tap.

WORKS OFFLINE
Log the expense on the subway or in the basement supermarket. It's saved on your phone and syncs on its own when you're back online, in the order you entered it.

THREE TAPS TO LOG
Amount, list, category. Done. Date, note, receipt photo and tags are there if you want them, never in the way.

OR JUST SAY IT
Hold + and say one or more expenses: "12,000 at the supermarket, it's shared; and 3,500 for gas, mine". dupla makes a card for each one,with the amount, category, who paid and tags, and you review them before anything is saved.

MORE THAN A LEDGER
• Personal and shared budgets with monthly limits
• A shared savings goal you both contribute to
• Shared lists for groceries, wishes and trips
• Recurring expenses: rent, bills and subscriptions load themselves every month
• Monthly stats by category and by tag
• Mercado Pago sync (optional): your movements arrive on their own and you pick which to log

TWO APPS, ONE REALITY
Pair once with a code. Each of you uses your own phone, even on different platforms. Each of you picks a theme (thirteen to choose from), a language and a display currency. The shared part syncs on its own.

YOUR DATA, YOUR RULES
We never ask for bank credentials. If you want, connect Mercado Pago from Settings: you authorize it on Mercado Pago's own page, dupla only reads your movements (it can't pay or move money) to suggest them as expenses, and you decide which ones to log. Disconnect any time.Without that connection nothing is read: you enter expenses yourself. If you add expenses by voice, the recording is turned into text byoutside services and deleted as soon as it's processed. Export everything to CSV any time, and delete your account from inside the app.

Start solo and invite your partner whenever you like.
