Calm Screen helps parents choose children's TV shows that leave kids calm — not bouncing off the walls. Every show is rated on a 1–10 stimulation scale across five science-backed dimensions. You get a clear score, a detailed breakdown, and confidence indicators showing how well-validated each rating is — all before you press play. WHY IT MATTERS Research shows that fast-paced, high-stimulation content affects children's attention, sleep, and emotional regulation. Calm Screen makes it easy to tell the difference between a show that winds kids down and one that winds them up. WHAT YOU GET • 235+ rated shows across 20 streaming platforms including Netflix, Disney+, Apple TV+, PBS Kids, YouTube Kids, and more • 5-dimension breakdown chart per show — see exactly what drives the score • Multi-source ratings — AI estimated, research calibrated, expert reviewed, and community validated • Confidence indicators — know how well-validated each rating is (Low, Moderate, High) • Your View — rate shows yourself, adjust scores, and add notes • Filter by platform, stimulation level, age range, and genre • Today's Pick — a fresh calm recommendation every day • Wind-Down Picks — extra calm shows surfaced automatically after 5pm • Browse by Category — Bedtime, Learning, Creative, and Nature shows • Quick Lookup — type any show name and get a rating in seconds • Watchlists — save approved shows per child profile • Multiple child profiles — manage different age groups with one app • Fully offline — no account, no tracking, no ads THE 5-FACTOR RATING SYSTEM 1. Pacing — How fast scenes cut. Slow = calm, fast = overstimulating. 2. Visual Stimulation — Colour saturation, complexity, and on-screen motion. 3. Audio Intensity — Music tempo, sound effects, and voice style. 4. Narrative Intensity — Conflict, suspense, and emotional stakes. 5. Engagement Hooks — Cliffhangers and design patterns that maximise watch time. MULTI-SOURCE VALIDATION Every rating is transparently sourced. Shows progress from AI-estimated scores through research calibration, expert review, and community validation. You always know where a rating comes from and how confident we are in it. STIMULATION LEVELS • Very Calm (1–2.5): Ideal for bedtime and wind-down • Calm (2.5–4): Great for everyday viewing • Moderate (4–6): Suitable for daytime with breaks • Stimulating (6–8): Best limited; avoid before sleep • High Stimulation (8–10): May affect behaviour and sleep SMART RECOMMENDATIONS The home screen adapts to the time of day. After 5pm, Wind-Down Picks appear first — showing only shows scored ≤2.5. Today's Pick uses a daily rotation so you always have a fresh suggestion. Browse by Category puts bedtime shows, learning shows, and more one tap away. PRIVACY FIRST All data stays on your device. No account required. No analytics. No ads. COPPA compliant. Child profiles are stored securely and never leave your phone. Designed and rated by parents, informed by research from the American Academy of Pediatrics and peer-reviewed studies on media and child development.
