Raise a little
money whiz.
Toby the Jar turns chores, birthday money and first jobs into coins your kids can spend, save — or plant and watch grow. Ages 5–13.
Free with one child · No ads · No subscription. Ever.
Three moves. One big lesson.
No "interest", no "lockup", no finance words ever reach a kid screen. Coins get planted, wait a few sleeps, then get harvested.
Earn
Do a job, tap "I did a job!" A coin drops in with a thunk. You approve it — birthday and pocket money count too.
Plant
Plant a coin in the soil. It locks — can't be spent — and Toby counts the sleeps. "3 more sleeps…"
Grow
Morning! It grew into a bigger coin — at the rate you set. A full-screen cheer, before breakfast.
Say hi to Toby.
He's not a piggy bank — he's a character. He blinks, he grins, and he keeps the coins safe. Kids raised on animated films bond with characters, not containers.
Tap his lid. Poke his eyes. Give him a shake. 👉 Go on — he likes it.
Toby has secrets. Curious fingers get rewarded — never told off.
Free means free. No subscription.
Most pocket-money apps charge every month, forever. GrowthJar asks once — or nothing at all.
The complete app — nothing held back.
Add every sibling — each with their own jar, rate and pace.
🍎 Pay once on your iPhone — GrowthJar works across all your devices and shares with the family through Apple Family Sharing. No second purchase, no per-device fee.
You set the rules of the universe.
Everything lives behind Face ID or your PIN. GrowthJar proposes; you decide. Nothing changes a jar until you say yes.
Tidy the Lego +20p
The growth rate
A big 25% a week for a 6-year-old, or realistic single digits for a teen. Your call.
The wait
How many sleeps a coin needs before harvest. Long enough to feel it, short enough to stay exciting.
Every approval
Every job, every deposit, every spend — nothing counts until a parent taps yes.
Per child
A 6- and a 9-year-old aren't the same. Different rates and waits each — siblings notice fairness.
The only network feature in the whole app is the optional unlimited-kids unlock, processed by Apple — and this website has no cookies, trackers or third-party code either. Read the full privacy policy; it's short, because there's nothing to disclose.
Not a bank. Better: a lesson.
GrowthJar never holds, moves or touches real money. It's a beautiful scorekeeper for your family's own pocket-money agreement — like the paper chart on the fridge, but one that teaches growth. When your child "spends", you hand over the real coins.
The app keeps score; you keep the cash. No card to load, nothing to hack, nothing to lose — and nothing between you and your child except a jar you both believe in.
A dad, a 5-year-old, and one stubborn idea.
I'm a dad in Buckinghamshire. I built GrowthJar for my son Gus, aged 5 — because I wanted him to learn to grow his money, not just save it. Piggy banks teach you to wait. I wanted something that teaches real money skills.
Toby is the friend who makes that feel like play. First his jar, then his sister's — and now yours.

Everything's already in the box.
No "coming soon", no roadmap teasers, no locked features waiting for a subscription. Here's what your family gets the moment you open GrowthJar.
Jobs & rewards
Set the chores and what they're worth. Kids tap "I did a job!" and a coin drops in — you approve it.
Plant & grow
Lock a coin in the soil and it grows at the rate you set, once the sleeps are up.
Harvest cheers
A full-screen celebration the morning a planted coin matures. It waits for them.
Per-child settings
Each kid gets their own jar, growth rate and pace — because fair isn't identical.
Parent gate & approvals
Face ID, a maths challenge, or your PIN. Nothing counts until a grown-up says yes.
Deposit photos
Snap an optional receipt for real cash added to the jar — stored on your device only.
Know a family who'd love this?
GrowthJar has no referral codes and no growth hacks — it spreads one school-gate conversation at a time. If someone asks what it is, here's the whole pitch:
"It's like a piggy bank, but the money grows if they don't spend it — and it's not a subscription."
And when your own child's coin matures, the celebration screen has a quiet "Share this moment" button — a parent action, never a kid one. It makes a little card like this for the family group chat. First name only, no links, nothing tracked.
Get words to pass it on Pre-written messages, plus a printable job chart for the fridge.
Straight answers.
Is this real money?
No — and that's the point. You keep the cash; Toby keeps score and teaches. No card, no balance, no bank.
25% a week?! Really?
It's an example — the rate is yours to set. For a 6-year-old, exciting beats accurate; the lesson is "waiting makes it grow". Dial it down as they get older.
Isn't the "growing" bit gambling?
No. There's no chance and nothing is ever lost. The growth is simply a number you set as the parent, and every planted coin comes back bigger by exactly that amount. It's a lesson about patience, not a financial product.
What'll it cost?
Free with one child, forever. £6.99 once unlocks unlimited kids. Never a subscription — worth saying twice: no subscription.
What do I need?
An iPhone on iOS 17 or later. GrowthJar is UK-first — pounds and pence. There's no Android or web version, and we'd rather say so than tease a "coming soon".
Can we get it now?
Yes — GrowthJar is on the App Store, free with one child. Five minutes to set up, no account, nothing to sign up for.
Tonight: install. Tomorrow: "DAD — IT GREW!"
Five minutes to set up. No account. Free with one child.
