Why people use IOUjar
Make small moments feel real
The best parts of relationships are often tiny. IOUjar helps you notice them and keep them.
Make accountability playful
Bets, chores, dares, and promises feel lighter when they become a shared game.
Keep your inside world alive
Inside jokes and sweet gestures usually disappear in chat. Here, they become something you build together.
Easy enough to actually use
A coin is a tiny action, so it's simple to keep coming back.
Built for any shared dynamic
However you connect, there's a jar for that.
Couples
For laughs, sweet gestures, promises, date ideas, and the little things that make your relationship yours.
Friends
For bets, dares, coffee debts, trips, and jokes that keep coming back.
Families
For chores, milestones, appreciation, and everyday moments worth noticing.
Teams
For shoutouts, mini rewards, fun accountability, and shared rituals at work.
Not everything worth counting is serious
Some things don't belong in spreadsheets.
IOUjar gives shared moments a place of their own — playful, private, and easy to return to.
