Four things happen, and the week runs itself.

Step one

Add your kids and pick your currencies.

Start with one currency if that is all you have the energy for. Screens is where most families begin, because it is the argument they are having most often.

One price covers the whole family, up to 15 kids — so cousins and the neighbor's kid can be in there too.

Step two

Log it while it is still happening.

Two taps, in the kitchen, with the kid standing right there. Say what they did and why it counted. That sentence is the part that teaches.

Tickets work the same way, except they buy you time: the conversation waits for the weekend, when nobody is mid-meltdown.

Step three

Payday, with the math already done.

Sit down once a week and the tally is waiting. Celebrate what went well, restate the rules, name the one thing to work on next week.

Because it is the same time every week, kids start keeping their own score in their heads. That is when the nagging drops off.

Step four

Hand it over to them.

Kid Mode gives each kid their own balances and the list of what is up for grabs. They pick the chores they want instead of waiting to be chased.

Spending comes out of their pile, not out of a debate with you.

Up to 15 kids

One price, however many kids you have. Free to try first.

Paper or phone

The app and the printed bills use the same five currencies. Run either, or both.

A minute a day

Log as it happens. Nothing to catch up on before Payday.

Try it on one currency this week.

Pick the argument you are tired of having, put a budget on it, and see what happens by Saturday.
