Agree on a fair rule before choosing who pays
Use a finger picker only for a voluntary, low-stakes group choice after everyone agrees to the possible cost.
Quick answer
Agree on the amount and the rule before using a picker to decide who pays for a small shared item. Finger Picker Chooser makes a casual selection; it does not collect money or enforce an agreement.
Step by step
Make the cost explicit
Everyone should understand the possible payment and freely agree. Use ordinary bill splitting if someone is uncomfortable.
Choose one participant
Use the supported single-winner flow with two to five fingers. Do not change the rule after seeing the result.
Handle payment separately
Complete payment through your normal method. The app does not transfer funds or verify that anyone paid.
A practical example
Friends who have already agreed can select who buys one inexpensive shared snack. For a larger bill, use a transparent split instead.
Before you use the result
Avoid pressure, financial stakes participants cannot afford or claims that the selection is legally certified. Participation and the payment rule should remain voluntary.
