For your child
Learning that feels like play
Short lessons, an island full of companies, and a streak worth keeping.
Bite-sized lessons
130 short lessons, from needs and wants to index funds. Read, practise, then a quick quiz.

The Island Market
Ten made-up island companies, with ups and downs of their own. Your child invests game money, reads the island news, and sees how their picks do against the steady fund.

The Time Machine
Slide forward to 18, 30 or 65 and see what time could do to their savings. Set a goal and watch how close it gets.

Streaks and rewards
Each lesson keeps a learning streak going and earns Squids, the game money. Collect cards and badges along the way.

For you
You stay in the loop
See what they’re learning, cheer them on, and keep the real decisions with you.
See their progress
Lessons done, levels and streaks for each child, at a glance.

Set the rewards
Choose what their streak milestones earn, from bonus Squids to a real pledge into their fund.

You make the real calls
Your child can ask to invest. You say yes or no, and any real trade is yours to make. We never hold or move money.

Keep it simple, give it time
The ideas behind every lesson. None of them are new, and they work best when you start young.
Start early
Time is the biggest help a young investor has. A little now can do more than a lot later.
Keep it simple
Low-cost funds that spread money across many companies, so no single one can sink you.
Let time do the work
Growth builds on growth. Stay invested through the ups and downs and let the years add up.
Learn by trying
In the Island Market, children pick companies and see how they do against the steady fund. Mistakes cost only game money.
Free family investing calculators
Run the numbers for yourself. No sign-up needed.
Questions parents ask
What age is it for?
Squids-In is designed for children aged 10 and up. Younger children can join in with a parent alongside them.
Is it real money?
The game money, called Squids, is virtual and can’t be cashed out. Real Junior ISAs and Junior SIPPs stay with your own provider, under your control. We never hold or move money.
Does it give financial advice?
No. Squids-In teaches how investing works. It doesn’t recommend investments or tell you what to buy.
Is my child’s data safe?
We collect only what the app needs, we never sell it, and a parent can delete the family’s account at any time. Read our privacy policy.
What does it cost?
Squids-In is free for families in the beta.
Does it work on Android and iPhone?
Yes, and in a web browser too, so a child without a phone can use a family computer or tablet. During the beta the apps are shared by invitation, so you won’t find them in the app stores yet.

Grow with us from the start
