Safe & private
Nothing to sign up for. Nothing to hand over.
StarJar asks for as little as possible. Your family is simply a few linked phones, so there's no account to make, no password to forget and no inbox to fill.
No password
Another phone joins your family by scanning a one-time QR code that expires in 10 minutes. Grown-up things sit behind a 4-digit parent PIN.
Nothing to install
It runs in the browser on iPhone and Android. No app store, no download. Want an icon? Add it to your home screen and it opens like an app, even offline.
No ads
No ads, no pop-ups and nothing to buy inside the app. Just your family, your deeds and your stars.
- Kids never type. Big buttons and pictures, nothing to spell.
- No chat, ever. Friends can only send ready-made stickers and silly fun tools.
- Parents decide. Friends come only from events you join, families you invite, and brothers and sisters. You can remove a friend any time.
- A kid's own phone stays a kid's phone. It has no parent mode, so stars can only come from a grown-up.
For parents
Less nagging. More noticing.
Kids do lots of good things that slip by. StarJar makes catching them as quick as a tap, so praise becomes a habit and rewards feel fair.
One tap to say "well done"
Ready-made deeds such as Tidied up or Homework done. Change them any time, and Undo works for 24 hours.
Rewards you choose
You set the gifts and their star prices: ice cream, a movie night, a new book. Kids save up and ask; you approve.
Every phone in the family
Mum's phone, Dad's phone, grandma's, and the kids' own phones all stay in step. Stars you give offline are sent when you're back online.
Fair for brothers and sisters
Every kid has their own jar and buddy. Shared a chore? Give everyone a star at once with the Both button.
A gentle nudge
Optional notifications when a kid asks for stars or a gift, in each phone's own language.
Star races with other families
Run an event for a holiday trip or a class, with your own deeds and prizes. Event stars never touch home stars.
For kids
Watching the jar fill up never gets old.
Kids see their effort turn into stars, pick their own goals, and learn that good things add up.
Pick a buddy
20 buddies who cheer, dance and wave. Tap one!
My own star jar
Choose a goal and watch every star land in the jar until it's full.
"I did something good!"
Kids tell you about a good deed with one big button. A grown-up decides the stars.
Big celebrations
Confetti, a dancing star and a parade of buddies when a goal is reached.
English and 中文
Each phone picks its own language, so grandparents can join in too.
Star friends: silly, never scary
Kids can cheer on friends and brothers and sisters with stickers that rain down their screen, and fun tools unlocked by stars they've earned. No typing, no chat, just giggles.

Spot it, star it
See something good? Tap a star. Your kid's phone celebrates, the jar fills, and gifts come when they've saved enough.
More phones? In Settings → Family phones → Add a phone, show the QR code and scan it with the other phone. Done.
Questions parents ask
Is there really no sign-up?
Really. The first phone creates your family and shows a recovery code once. Keep it somewhere safe: if every family phone is lost, it brings all your stars back.
Do I have to install an app?
No. StarJar opens in the browser on any recent iPhone or Android phone. You can add it to the home screen for an app icon, full screen and offline use, but you don't have to.
What does StarJar keep about us?
Only what the app needs: your kids' names or nicknames and buddies, your deeds, stars, gifts and events. No email address, phone number or password.
Can my kid talk to strangers?
No. There's no chat at all. Kids only see star friends from events you've joined (the host approves every family), families you invited, and their brothers and sisters. They can only send ready-made stickers and fun tools.
Can both parents use it?
Yes, add as many grown-up phones as you like, plus a phone for each kid. Everyone sees the same stars, and the parent PIN keeps grown-up things grown-up.
How much does it cost?
StarJar is free to use, with no ads and nothing to buy inside the app.
