Cairn is a mobile app that helps parents confidently support their child's development, from birth to age five, through the everyday moments they already share together. It brings together developmental tracking, simple activities, and guidance from pediatric therapists, all built around one idea: children grow through interaction, not screens or worksheets.

Any parent or caregiver who wants a clearer picture of how their child is growing, and simple ways to support them day to day. Cairn is also built to work alongside early intervention providers and regional centers, giving families an accessible first step and a way to stay connected to their child's plan over time.

Cairn is currently in development and not yet publicly launched. We're working with regional centers and providers now to make sure the app truly supports families and fits naturally into existing early intervention services before we open it up more broadly.

Birth through five years old, the window when early intervention has the greatest impact on a child's development.

Every piece of content in Cairn, from milestones to activities to check-in questions, is written and reviewed by pediatric speech-language pathologists and early intervention specialists with direct clinical experience. Nothing is added to the app without a clinician reviewing it against the research first.

Cairn's milestones are drawn from established, peer-reviewed developmental research and public health guidance, including CDC and American Academy of Pediatrics milestone guidelines, and are cross-checked against standardized developmental assessments already used by early intervention providers. Each milestone is tied to a specific source, not general knowledge or opinion.

Yes. Cairn's milestone list and check-in questions are built on hundreds of verified research sources and mapped, item by item, to standardized developmental tools. As more families use Cairn, that evidence base continues to grow and get more precise.

Most milestone apps hand parents a checklist and stop there. Cairn is built by clinicians who work with children with developmental delays every day, so it doesn't just tell parents where their child is. It shows them what to do next, in language that's clear and encouraging and grounded in real therapeutic strategies, not generic tips.

No. Cairn is a developmental support and information tool, not a diagnostic tool. It helps parents notice patterns and stay informed between visits, and it always encourages families to talk with their pediatrician or an early intervention provider when something is worth a closer look.

It means families whose services are authorized through that regional center can use Cairn as part of their supports, with Cairn's clinical team available to help guide their care alongside the family's existing service coordinator.

In addition to full access to the app, regional center clients are paired with a licensed therapist on Cairn's team who regularly reviews their child's plan and progress and is available to support the parents directly along the way. It's the same clinical judgment a family would get in a therapy room, built into their everyday use of the app.

No. Cairn is designed to complement, not replace, direct therapy and existing early intervention services. It gives families a way to stay engaged and supported between visits.

Protecting family privacy is a foundational part of how Cairn is built. We're careful about what data we collect, how it's used, and who can see it, and we're finalizing our privacy practices ahead of launch. Full details will be available in our privacy policy at that time.
