An IOU is more than a number

Most IOU apps store an amount. PayMeLater stores the story: theatre tickets, the cabin deposit, groceries for the trip — each with a date attached. Six months later, £445.68 isn’t a mystery you have to argue about; it’s a list you can both read.

On the record

Every edit leaves a trail

Change an amount, settle early, fix a typo — every change is written into a dated history that both sides can see. When the record keeps itself, nobody has to take anyone’s word for anything. That’s what keeps IOUs friendly.

Private by design

Your ledger is nobody’s feed

No social feed, no followers, no selling your data. Your IOUs stay between you and your friends — and your friends don’t even need the app. It’s a notebook, not a network.

Questions, answered

Is the IOU tracker really free?

Yes — PayMeLater is free to download and use, with no ads. Tracking IOUs with friends costs nothing, and an optional premium adds extras if you ever want more.

Does my friend need the app for me to track an IOU?

No. PayMeLater is your own private ledger — you can log what anyone owes you (or what you owe them) without them installing anything. If they join later, the shared bills that name them are waiting, and from then on you both see the same record, kept in sync.

Can I track IOUs in different currencies?

Yes. Type an amount in any currency and it converts at that day’s live rate. The rate and date are saved with the IOU, so the record stays honest.
