Dupla
PausedFinancial management for couples
Overview
Dupla is a money management app for couples that treats finances as part of the relationship, not just a spreadsheet. Instead of only adding up spending, it helps both partners define how money actually works between them: who decides what, how expenses get split, and what counts as "ours" versus "mine" and "yours".
Most money fights between couples don't come from a lack of tracking; they come from a lack of agreement. An estimated 40% of relationship conflicts involve money, usually because the rules were never made explicit. Grounded in behavioral finance, Dupla turns those unspoken rules into clear, written agreements the two can revisit and adjust together.
With a shared space to log expenses, flexible split rules, and a guided monthly check-in, couples follow the numbers in real time and talk about money with structure, so a single purchase doesn't turn into an argument. Data is encrypted, with permission controls for both partners.
The problem
Couples who run their finances together rarely argue for lack of a tracking app; they argue because they never set the rules together. One partner earns more and a 50/50 split starts to chafe; one makes every decision while the other is left out; big purchases become negotiations; and the line between "mine", "yours", and "ours" stays blurry. Without an explicit agreement, every month reopens the same conversation. Dupla is built to settle the agreement, not just the math.
Who it's for
- Couples who share expenses and want clear rules
- Partners with different incomes looking for a fair split
- Couples whose money talks tend to become arguments
- Anyone wanting to separate "mine", "yours", and "ours" without friction
- Couples planning shared goals and big purchases
How it works
- 01
Agree on the rules
Decide together how money works: the split method (50/50, income-proportional, or custom), what's shared, and who decides what.
- 02
Log it in one place
Every expense goes into a shared space that both partners can follow in real time.
- 03
Run the monthly check-in
Once a month, the app walks you through a guided conversation, with reconciliation and projections, so you close the month without replaying the same argument.
