For families in the tooth fairy years and beyond
Turn the tooth fairy into your child's lesson in saving.
Meet Jarly, who holds every coin and keeps the lessons going all year.
A lost tooth is when kids care most about their teeth and their money. LumiJar makes it count: the fairy's coins land in Jarly, and your child sorts them, saves for a goal and watches it fill. Between teeth, Jarly keeps going with missions, allowance and goals. You stay the bank: no real money, no cards, no ads.

From the note under the pillow to Jarly saying hello. Sound on.
A ritual you already love, with a lesson inside
Nothing new to invent. LumiJar follows the moments your family already has, and you don't need a wiggly tooth to start.
A tooth comes out.
Log it in the tooth chart. When they first open LumiJar, your child names their very own tooth fairy, and from there on the fairy is theirs.
The fairy visits.
You send her visit. That night her coins arrive in a trail of stardust, with a note you write in her name.
Your child decides.
The coins land in Jarly. Your child sorts them into Savings and Spending, picks a goal and watches it fill.
The magic stays magic
Your child's fairy is never pictured. They only ever see what she leaves behind: the glow of her wand, her wings, and a trail of stardust across the night.
When a big moment arrives, like the very first tooth, she signs a certificate in stardust. It's yours to save or share.
Money habits that grow with them
Between teeth, Jarly keeps the lessons going with allowance, missions and goals.
Savings and Spending.
Two jars, one choice every time money arrives.
Goals.
A bike, a book, a game. Waiting becomes the fun part.
Missions.
Chores you set, worth what you decide.
Badges.
Earned for saving and missions, revealed with a scrub of the toothbrush.
Three levels that grow with your child
Small moments, all year
LumiJar gives your family everyday reasons to cheer each other on, between teeth and long after the last one.
A mission, noticed.
They finish a chore, you see it and approve it, and the coins land in Jarly.
A yes to a goal.
When a goal fills up, your child asks to get it. Saying yes is yours to give.
A letter from the fairy.
Now and then, a note in her name, written by you. She notices what they did, because you did.
No chatbot, ever. Jarly's words are written ahead of time, and every letter from the fairy is written by you.
You stay in charge
Built for families first, and for children's privacy from the very first line of code.
You're the bank.
Virtual money only, and no card to link. You approve every request, and say yes before a goal is paid out.
Calm by design.
A few minutes around real moments. No ads, no endless feed, and no notifications nudging your child back.
Private by design.
Parental consent before any child profile is saved. No ads, no data sales and no tracking in the app. Delete your account any time.
Teeth, too.
A tooth chart that becomes a keepsake of every lost tooth, with the date, and your notes and memories.
Made by a board‑certified periodontist who teaches
LumiJar was created by Dr. Ryan Wong, DDS, MS, a board-certified periodontist and dental school educator in Los Angeles, to pair two habits that begin in childhood: caring for your teeth and caring for your money.
Questions parents ask
Is it real money?
No. Balances in LumiJar are virtual and you act as the bank. When your child wants to spend, they ask, and you hand over the real money however you like.
Does my child need their own device?
No. Kids can use LumiJar on your phone, each with their own PIN, or you can link a family tablet with a one-time code.
Is there AI talking to my child?
No. There's no chatbot in LumiJar. Jarly's words are written ahead of time, and every letter or note from your child's fairy is written by you.
What age is it for?
LumiJar is for families in the tooth fairy years and beyond. Three levels grow with your child, so it keeps up as they do.
What happens to my child's data?
We collect only what the app needs, never sell it, and show no ads. There's no tracking in the app, and you can delete your account at any time. Read the privacy policy.
