Free group calculator
Who pays next?
Tap through the sample, or build your actual group before signing up. Pay Pong puts anyone who has never paid first; after that, the person whose latest payment is oldest is next.

How does the calculator choose who pays next?
Anyone who has never paid is next before someone repeats. Once everyone has paid, the person whose latest payment is oldest moves to the front.
Can I turn this into a real group?
Yes. Choose Build your group, add the people and any real prior turns, then sign in. Pay Pong creates the same rotation without making your friends register first. The setup is saved only in this browser until you create the group.
What does it not calculate?
It does not compare bill amounts, calculate debt, or move money. Use a bill-splitting app when exact reimbursements matter.
