Money is more fun when you're Kidding Around!

The free money app from the DD Brothers. Kids track their pocket money, fill six savings jars on a money tree and learn money tricks with videos, quizzes and games.

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.

The six jars from the book

The Oopsie Poopsie Fund fills first – then the rest is shared out.

Cash Coins are play money for games only – they can never be bought with real money. No ads to kids, no in-app purchases.

Watch the DD Brothers Adventures

David and Denis travel through money history, meet Mr FX, Mrs Piggy and the Caveman – and every episode ends with a quiz.

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.

Privacy notice – launch news

Who we are. Kidding Around with CASH, from the creators of the DD Brothers Adventures and the book Kidding Around with Cash. Contact: ddbrothers@kiddingaroundwithcash.com.

What we keep. Your email address, the country you choose (optional), whether you also want tips and offers, and when you signed up and confirmed. Nothing about your child.

Why. To send you one email when the app launches – and, only if you ticked the second box, occasional money tips and offers for grown-ups (about every 2–3 months). We use your consent, which you can withdraw any time.

Double check. We first send one email to confirm the address is yours. If you don't confirm, we delete it automatically after 7 days.

Where. Stored in the EU (Supabase). Emails are sent with Resend (EU) and the website runs on Cloudflare. They only process the data for us. We never sell or share your email.

How long. Until you unsubscribe (link in every email) or ask us to delete it.

Your rights. You can ask to see, correct or delete your data, and complain to your country's data protection authority.
