Sound familiar?

We all lend things.
Nobody remembers.

It starts with one borrowed book. Then a charger. Then a tenner for coffee. Before long you have lost track of half your stuff and feel weird asking about it.

📚

Where did my book go?

You lent it months ago. They forgot. You forgot. Gone.

💰

Who owes me?

You paid for dinner, covered the round, fronted the deposit. It adds up.

📦

Did I return that?

You borrowed a drill, a dress, a charger. You think you gave it back. Probably.

📅

Library fine. Again.

The return date crept up. Peni would have reminded you three days earlier.

How it works

Follows you through
the whole thing.
