Sound familiar?

Your memory is full.
Let Peni handle it.

We all lend things to people we trust. The problem is life gets busy, and you lose track of what went where.

📚
Where did my book go?
You lent it three months ago. They forgot. You forgot. The book is gone.
💰
Who owes me money?
You paid for dinner, covered the round, fronted the deposit. Keeping track is exhausting.
📦
Did I return that?
You borrowed a charger, a tool, a dress. You think you gave it back. You are not sure.
📅
Library fines again?
The return date crept up and you missed it. Peni reminds you before it happens.
