We've been there too.

One evening, after yet another discussion about "who paid for what" this month, we realized the problem wasn't money. It was the lack of visibility. Each of us felt like we were paying more than the other, with no way to verify it objectively.

We tried shared spreadsheets, solo budget apps, notes on the fridge. Nothing worked. Either it was too complex, or it didn't account for the reality of being a couple: separate accounts, shared expenses, different incomes, and sharing rules that change depending on the situation.

So we built Koupli. A tool designed from the ground up for couples. Not a solo tool with a "sharing" mode added as an afterthought. A tool where financial transparency doesn't mean surveillance, but peace of mind.
