Every IOU, never forgotten.

A private ledger for money you lend to and borrow from friends and family. Log who, how much and when it’s due, attach proof, and watch balances update as repayments come in. Everything stays on your phone.

features


Lent & borrowed

Track money you gave and money you owe separately, with Open, Partial, Overdue and Settled statuses at a glance.

Repayment timeline

Record full or partial repayments and see the remaining balance for every entry and every person.

Proof attachments

Attach a photo, video or voice note to any entry so there’s never a question about what was agreed.

Overdue reminders

An optional daily reminder nudges you about entries that are past their due date.

Reports & charts

Per-person balances and reports with charts show where your money is and who still owes what.

Private by design

Biometric sign-in, on-device storage and CSV export/import, so your records stay yours.

Made for you

English & Bangla, BDT & USD, and multiple themes to suit your taste.

how it works


  1. Add an entry

    Pick a person from your contacts or type their name, enter the amount, whether you lent or borrowed, and the due date.

  2. Attach proof

    Optionally snap a photo, record a video or leave a voice note with the entry.

  3. Log repayments

    As money comes back, add repayments. IOU updates the status and balance automatically.

  4. Stay on top of it

    Get reminders for overdue entries and check reports to see the full picture.

privacy


Everything you enter into IOU is stored in a database on your phone. IOU has no server, and I never receive your ledger, account details or attachments. The only data that leaves your device goes to Google services used for ads, usage analytics, purchases and app updates.
