Money between two people, written down once and agreed by both
DuoDue is a shared record of one obligation between exactly two people: what you agreed, what has been paid, and what remains. Nothing counts until both of you have confirmed it.

How it works
- 1
Write down what was agreed
The amount, the currency, and how it is paid back — all at once, or in Installments on a Schedule that ends on a Debt-Free Date.
- 2
Invite the other person
Send them an Invitation. They sign in with their own account and accept the Terms, or propose different ones. Nothing is active until both of you agree.
- 3
Confirm every Payment
One of you records a Payment and the other confirms it. You both see the same balance, on your own phones, in your own Language.
Only the two of you can see what is owed and what has been paid.
