The toothbrushing app that connects your child to the people they love.
For kids ages 6–12
Your child brushes. Their island grows. Brush together and it grows faster.
Backed by 2 years of research with families and dental experts across Belgium
A consistent 2-min ritual, compliance that feels like a win, not a chore.
Bridges distance and busy schedules. Everyone in their circle becomes a quest partner in your child's daily life.
Shared quests, rewards, and adventures that make every session feel like progress in a bigger story.
Every night, the same fight
You're exhausted. Your child has decided brushing is not happening tonight. And somehow it becomes the battle nobody wins.
of children lie occasionally about brushing teeth
of children are not supervised twice a day when brushing
The truth: Bad brushing isn't a child problem, it's an engagement problem, and we set out to fix it.
What if brushing was something your child looked forward to?
Your child brushes, the island grows
Every time your child brushes, a new tree appears, a house gets built, a waterfall starts flowing. The island reacts to every single brush. Your child sees it happen in real time.
Grandma brushes too, and magic happens
When grandma brushes in her house, even 200km away, something new appears in your child's island. They play the same game from different places. They need each other to make it grow.
You see everything. Without asking once.
The app uses your phone camera to detect brushing quality, on the device, nothing uploaded. You see how long your child brushed, how well your child covered every tooth, and whether grandma brushed too. No guessing. No fighting. Just peace of mind.
Built one brush at a time
- Brush, it grows
- Brush together, it grows faster
- Spend credits, build it your way
- Always something new to discover
You decide when the fun begins.
Your child earns credits by brushing, but can only spend them when you unlock building time. Brushing stays a two-minute habit. Not a gateway to more screen time.
Built with the people who know oral health best.
Otty is developed in close collaboration with leading academics, gerodontologists, dentists, and oral health researchers across Belgium, the Netherlands, and the United States.
Detected on-device. Never recorded.
The camera only sees what the AI needs to coach the brushstroke. Faces are anonymised, the bathroom is blurred in real time, and no raw video ever leaves the phone.
On-device AI
Brushing is detected locally. Nothing is uploaded, nothing is stored.
Faces anonymised, background blurred
The bathroom and your child's face are obscured in real time.
Parent-controlled filters
You choose what your child sees. Pick from playful AR filters (like the superhero mask) and adjust strictness, so you trust the experience 100%.
GDPR safe by default
Built in Europe, audited for compliance, designed around your family's privacy.
No more guessing.
No more wondering if your child really brushed. No more arguments at the bathroom door. Open Otty and see exactly how your child brushed today, calmly and clearly.
