Teaching kids the value of money
A physical piggy bank with a digital heart. Tap your phone to deposit, watch savings grow in real time.
How it works
Simple enough
for any parent
No complicated setup. No subscription fees for basics. Just tap and save.
Set up the piggy bank
Tap your phone to the physical device to link it to your account. Give it a name like "Emma's Bank" and you're done.
Add money with a tap
Open the app, enter an amount, and tap your phone to the piggy bank. The balance updates instantly on the device's screen.
Watch savings grow
Set up interest, weekly allowances, and chore rewards. Kids can see their balance grow in real time — right on their desk.
Features
Everything a family
savings account needs
NFC tap to deposit
The physical ritual of tapping your phone to the piggy bank makes saving feel real and intentional. No more invisible digital money — every deposit is a deliberate act.
Built for families
Both parents can manage all kids' piggy banks from their own phones. Multiple banks, one app.
Interest & growth
Set a savings interest rate to teach kids how money compounds over time. Starts at 0% — you choose when to enable it.
Quick presets
Set up shortcuts for weekly allowance, chores, and birthday money so you're never typing the same amount twice.
Private & secure
Each family's data is completely private. Row-level security means no one can see your kids' savings but you.
"The best way to teach kids about money is to give them real experience with it — not just talk."
