Resilient Kids
Science of the first 400 weeks
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your child's first 400 weeks shape who they become.
Brain architecture, language, attachment, the immune system, the metabolic baseline — permanently shaped across the 400 weeks from preconception through pre-school.
Knowing the science isn't the same as living it. Resilient Kids distills the science of childhood development into a simple weekly sequence — one topic at a time, matched to the moment it matters most for your child.
- THE RIGHT TOPIC, AT THE RIGHT TIME
One science-backed topic per week, matched to your child's exact developmental stage. No reading lists. No catch-up. A sequence, not a library. Each topic comes with what to do this week, the reasoning behind it, and the evidence underneath.
- REVIEWED BY NAMED SCIENTISTS
Every weekly module names the scientific advisor who signed off. Recommendations follow a five-tier evidence hierarchy — systematic reviews and clinical guidelines first — and uncertainty is labeled directly. Every published version is hash-anchored on a public consensus log, so families and clinicians can independently confirm that what you read today is what advisors approved on the date stated.
— BUILT FOR EVERY CHILD, AND EVERY CAREGIVER
Each child you raise gets their own independent 400-week timeline. A toddler and a newborn don't share one feed — they each get their own program from one account. Multi-caregiver records keep grandparents, partners, and nannies aligned on the same weekly priorities.
— PLANS
Resilient Kids ($7.99/month or $79/year, 3 months free on both cadences): the full 400-week age-timed program for your whole family — up to 8 children on independent 400-week timelines, up to 5 total caregivers, weekly guidance, stage-based tracking, evidence notes, and advisor-curated content updates as the science evolves.
Monthly Guidance ($1.99/month): after the 400 weeks, or for an older child (ages 6 to 18) joining your household — age-timed guidance delivered monthly for the school-age years.
— DESIGNED FOR HOW REAL FAMILIES RAISE KIDS
• One topic per week, not a feed. A sequence, not a library.
• Per-child timelines that survive pauses. Skip a week — your history stays.
• Shared, conflict-free household record. Every caregiver sees the same priorities; each person's read state is their own.
• Time-zone-aware reminders, category-by-channel — only what you want, when you want it.
• Publicly verifiable content history. Every weekly version is anchored on a public chain.
— FOR FAMILIES. FOR CLINICIANS.
Resilient Kids is simple enough for families. Credible enough for professionals. The same content. The same evidence trail. The same advisor sign-offs — visible to both audiences.
— WHO IT'S FOR
Adult caregivers raising a child from pregnancy through age 18. Educational and supportive content — not a substitute for professional medical advice. Always consult a qualified healthcare provider for medical concerns about your child.
— REQUIREMENTS
iPhone running iOS 15 or later. Subscription required for full weekly content access.

Thanks to the caregivers who flagged where accessibility needed deeper care.
