IOU Jar

IOU Jar is a playful way to track the little things people owe each other.

Create shared jars for couples, friends, families, or teams. Use them for coffee runs, little bets, trip promises, snack debts, birthday treats, and all the everyday favors that are too fun to forget.

Set up a jar in seconds, invite others, and start dropping IOUs as moments happen. Every drop lands in the jar, so it feels simple, satisfying, and shared.

With IOU Jar, you can:

Create custom jars for any shared ritual or promise Set your own jar name, coin value, and color Invite others with a code or shared link Drop IOUs with a playful, live jar experience Add notes and keep track of recent activity Save your profile and stay synced across devices

Whether it’s “you owe me coffee,” “loser buys dessert,” or “we’ll save for that trip,” IOU Jar helps you keep score in a way that feels light, social, and fun.

Make the little promises count.
