## What is IOU Slip?

IOU Slip

Keep the promise. Record bonds, not debt.

In modern life, everything is settled with money.
But real relationships are not meant to be cleared.

IOU Slip is a lightweight app to record promises, favors, and unspoken bonds between people — not as money, but as memory.

What is an IOU Slip?

An IOU Slip is a digital note of a promise:
	•	“I owe you a massage.”
	•	“Next coffee is on me.”
	•	“I’ll help you anytime.”

It’s not a debt.
It’s a reminder of trust.

Cute concept, surprisingly fun to use.
We now send each other silly slips instead of simple transactions!
