How it works
Brushed teeth, read a book, helped someone. Green cards add coins, red ones take them away. One tap, no typing, no logging in every time.
The day gets added up and the coins pour into the jar. Miss a night and it sorts itself out in the morning.
Cash out for ice cream and a late bedtime, or hold your nerve and save toward the big one.
What's inside
Fills up in real time toward the next prize you can nearly afford.
A 500-coin track along the top for the thing worth waiting for. Spending small never sets it back.
Twelve stickers you can't buy — only earn. Streaks, perfect days, big totals.
Add every child in the house. Tap a name to switch. Same rules, separate jars.
For parents
Open it on the tablet you leave in the kitchen. It'll be ready the next morning.
