Our story

We built the support we wished we had.

It started with a phone call from the hospital. A few days after our son was born, his newborn screening revealed congenital hypothyroidism. At the follow-up appointment, we learned how to manage the basics: a few drops of medication every morning, on an empty stomach, and regular blood tests to monitor his levels.

Then we went home. With a treatment plan, but without a guide for everyday life.

The questions came quickly. Can he drink milk after his medication? What if he spits out a dose? How do we help grandparents and caregivers understand what he needs?

We searched for a tool that could help us navigate these daily challenges. Nothing existed. So we built ThyroKid: first for our own family, and now for every family facing a congenital hypothyroidism diagnosis.

ThyroKid combines lived experience with clinical expertise to support families with daily treatment management, trusted information, and greater confidence from day one.

Daily dose Available

The morning dose is the foundation of the treatment, and the core of the app. Set a daily reminder for whatever time works for you, and log each dose with a single tap. Your full history is always there when you need it at the appointment.

Feeding made simple Available

Know what to feed, and when.

For families managing congenital hypothyroidism, nutrition is part of the treatment routine. Certain foods can affect how well medication is absorbed, making timing and preparation important. ThyroKid helps take the uncertainty out of everyday meals with clear, practical guidance, so parents can make confident decisions without second-guessing.

  • Simple food guidance: safe, wait 2 hours, or wait 4 hours
  • Timing recommendations for different food groups
  • Breastfeeding and weaning guidance
  • AI meal analyzer to identify potential interactions. In development

Lab results In development

Understand the numbers behind your child's care.

After a blood test, families often receive results like TSH and free T4, but little explanation of what they mean or what questions to ask next.

We're building a module that helps put lab results into context: how values compare for your child's age, how they may change with treatment adjustments, and what to discuss at the next appointment.

No diagnosis. No replacing your doctor. Just clear information to help families feel informed and prepared.

This feature is currently in development. The image shows a design concept.

Share your child's care plan with confidence.

Your child's treatment continues even when you're not the one giving the medication. Keep grandparents, babysitters, teachers, and other caregivers informed with clear, up-to-date instructions, without endless texts, notes, or reminders.

We're building a module that helps everyone involved understand the essentials and stay on the same page.

  • Printable caregiver guide with the key information they need
  • Easy-to-understand medical guidance
  • Read-only caregiver access

The guidance we wished we had from day one.

Raising a child with congenital hypothyroidism comes with new questions at every stage: from breastfeeding and introducing solids to vaccinations, medication routines, and everyday situations like travel or pharmacy visits.

We're building a library of practical guides and short videos that give families clear, reliable answers when they need them most.

All content is designed for real family life: easy to understand, clinically reviewed, and available in the moments between appointments.

  • Step-by-step guides organized by age and topic
  • Short, practical videos with clear answers
  • Clinically reviewed content before publication

You don't have to navigate this journey alone.

A congenital hypothyroidism diagnosis can bring questions that don't always wait until the next appointment. Many families have faced the same uncertainties, challenges, and everyday moments you are experiencing.

We're building a trusted space where families can connect, share experiences, and support each other with people who truly understand.

  • A shared community feed for questions, experiences, and practical advice
  • Direct messaging to connect with other families one-on-one
  • Discover families with similar journeys and experiences

How the app works

Built for the daily routine.

01

Your child's profile

Name, medication, prescribed dose, and reference doctor. The app adapts to each child's treatment schedule.

02

The morning routine

Dose reminder, one-tap logging, and meal planning with the food traffic light.

03

Ready for the appointment

Dose history, noted questions, and educational material. You arrive at the endocrinologist with everything organized.

What we want to change

A diagnosis should come with support, not unanswered questions.

Newborn screening has transformed outcomes for children with congenital hypothyroidism. Today, most babies are diagnosed within days of birth and can start treatment early. But diagnosis is only the beginning. After leaving the hospital, families face years of daily medication, regular blood tests, and countless questions between appointments, often without a trusted source of guidance. That is the gap ThyroKid was built to close.

Today

Supporting families every day

Helping families manage the essentials of congenital hypothyroidism: medication tracking, nutrition guidance, and trusted education, available in three languages from day one.

Tomorrow

Connecting the full care journey

Expanding support with lab result insights, caregiver tools, travel guidance, and deeper collaboration with pediatric endocrinology teams.

Beyond

Building a new standard for childhood chronic care

Extending the ThyroKid model to support families managing other chronic conditions identified through newborn screening.
