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

Rewards worth learning for
Keep a learning streak and earn the rewards your parents set: bonus Squids for the game, or real money at milestones like 7, 30 and 100 days.

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.

For you
You stay in the loop
See what they’re learning, cheer them on, and keep the real decisions with you.
A postcard every Sunday
Their week in one card: lessons done, streak, Squids earned, what they learnt and a question to ask at dinner. Send an ink note back.
Rewards and a cash pot
Reward chores, learning or a birthday with real money. It waits in their cash pot until they ask for it: you hand over the cash and tick it off. Or they can move some to invest, and you can add a match. We never hold or move money.
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.
The tax-year tide
See how much of this year’s Junior ISA allowance is paid in, with no pressure to fill it.
Handover, in good time
From 15, a gentle reminder of when they take charge of their Junior ISA, so you can talk about it together first.
Keep it simple, give it time
The ideas behind every lesson. None of them are new, and they work best when you start young.

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.
