Who owes whom – all in one place
MoneyDue keeps track of money you've lent and money you owe: friends, family, colleagues, companies. It all lives on your phone, and the other person doesn't need the app.
Free. No account, no ads, nobody looking over your shoulder.


You lend a colleague £200, they pay you back in euros, then someone picks up the bill for everyone at the café. A month later, nobody remembers who's up.
Notes don't cut it. The currencies are different, partial repayments don't add up, and asking someone straight out is always awkward.
What it does

Repaid in another currency, at your rate
You enter the rate you actually got, and it stays attached to that payment.

Partial repayments
If half comes back, record half. The balance updates on its own.

A reminder you're happy to send
Gentle or direct. Change what you like and send it through any messenger.

Forgiving closes a debt too
Its own action, separate from a repayment. The amount and every payment stay visible.
Your records don't go anywhere on their own
MoneyDue works on your phone, even offline. There's no account: install it and start adding debts, with nothing to confirm and nothing to sign up for.
The database on your phone is encrypted with AES-256, and the key stays in the phone's secure storage. You can lock the app with biometrics or your device passcode, and while the lock is on, your debts are hidden when you switch apps.
No analytics, no ads, and we don't sell data.
