Money should bring you closer, not apart.
HeyDuo helps couples track shared expenses, split bills effortlessly, and take the guesswork out of money — all with a friendly AI assistant.
Snap receipts, forward emails, connect banks. Works on any device.
Hey! Try asking me:
Most couples have no idea where their money actually goes.
You just need a clear, shared system.
"Who paid for what?"
When you share expenses, you need the full picture — not a best guess.
"Is this split fair?"
50/50 doesn't work when incomes differ. Couples need flexible, transparent splitting that feels right for both.
"Where is all our money going?"
Without clear data, money conversations are just guesswork. With it, they take 30 seconds.
You don't need a joint account to manage money together.
Fully merged or completely separate — those aren't your only choices. HeyDuo gives you shared visibility with full independence.
Independent couples
You love each other — not each other's spending habits. Keep your own accounts, share only what matters.
Co-parents
Splitting kid-related expenses after separation shouldn't require a spreadsheet or a group chat.
Unequal incomes
50/50 isn't fair when one partner earns twice as much. Split by ratio, not by default.

Hey —
I'm Rom. My partner and I tried every app out there to manage our shared spending. Most of them just wanted to turn us into leads for banks. The rest were glorified spreadsheets.
Meanwhile, a $100 Amazon charge would hit our account and neither of us could tell if it was dog treats or our coffee subscription. We just wanted to be more conscious about where our money was going.
As an engineer, there's nothing better than building something you actually use. So I built HeyDuo — to see clearly, cut waste, and stop guessing.
We love giving access to people who are serious about getting this right.
If you don't pay for the product, you are the product. HeyDuo isn't free — we'd rather be paid by you than off you.
