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.
What’s New in This Version
• Added a new onboarding experience to help first-time users get started smoothly
• Improved visual details and interaction feedback across the app
• Refined layout and animations for a more natural, tactile feel
• General stability and performance improvements
This update makes IOU Slip clearer, calmer, and easier to use from the very first launch.
