What's inside the app
Based on the book Kidding Around with Cash – everything a young money hero needs, on phone, tablet or computer.

My Money Jars Tree
Six jars hang on a cartoon money tree – and grow as the savings grow. Reach every goal to unlock a seventh jar you name yourself.

My Money
Write down money in and money out, sort needs from wants, and use Mrs Piggy's "think before you buy" check.

Goal planner
Pick a goal and a date – Goldy works out how much to save each month. Too much? Get more time, or ideas to earn a little extra.

LEARN islands
Eight islands, one for each book chapter, with DD Brothers episodes, quizzes, mini-games and stickers to collect.

Games
Piggy Catch, Caveman Coin Run, Mr FX Currency Match and the Lemonade Stand – played with Cash Coins earned by learning.

Chores & earning
Kids tick off chores and earning ideas – a grown-up approves them, and the money lands in My Money.

Questions
How much does it cost?
The app is free for kids. Grown-ups may see our own products, or clearly labelled partner offers, in the grown-ups area only – never on kids' screens.
What age is it for?
Kids aged about 8 to 13 – older kids are welcome too. Children under the age their country allows can only join when a grown-up sets up their profile.
When does it launch?
We're testing it with a few families now. Leave your email above and we'll tell you as soon as it opens.
Can teachers use it in class?
Yes – the videos, quizzes and journal pages work well in class, and we're planning a teacher option that shows progress without any personal data. Email us if you'd like to try it.
Is this financial advice?
No. Kidding Around with CASH is a learning tool. It never handles real money – kids type in what they have, and a grown-up pays any real pocket money.
