MOONBOW — TRANSLATE YOUR CHILD'S BEHAVIOR INTO CLARITY Parenting a neurodivergent child means constantly translating their world for therapists, teachers, aides, and your partner. Moonbow is built for parents and caregivers who need less paperwork and more understanding in the moment. Stop tracking. Start translating. MEET LUMI LUMI is your behavior translator. Talk or type in plain language. Vent after a meltdown, a rough transition, or a win, and LUMI helps structure what happened into antecedent, behavior, consequence (ABC) insights you can actually use. NEW: PREPARE BEFORE THE MOMENT The new Prepare tab helps you plan ahead, not just log after the fact. Describe an outing, transition, or routine, and LUMI forecasts environmental prep: timing, sensory considerations, exit plans, and visual supports tailored to your child. When your clinician sends approved home practice items through Moonbow, you can rehearse them at home and share how it went. Self reported feedback your care team can see, not a clinical score. LOG IN YOUR LANGUAGE Choose English, Español, or 中文. LUMI listens and responds in the language that feels natural at home. Weekly clinical summaries and shareable PDF reports are written in English so you can hand them to your BCBA, teacher, or IEP team without translating. FROM OVERWHELMED TO CARE TEAM READY • Voice or text logging on Track, fast when you're stressed • Prepare tab: environmental forecasts and clinician approved home practice (Requires Premium subscription for practice runs) • History and patterns over time, not just one bad afternoon • Weekly clinical narrative: what's recurring, what's working • Clinical report (PDF): one tap for therapy visits and school meetings (Requires Premium subscription) • Care Circle: invite coparents and trusted caregivers (Requires Premium subscription) BUILT FOR REAL PARENT LIFE • Quick daily check ins • Optional Health context for caregiver resilience • Walkie style capture when your hands are full • Support timer on lock screen and Dynamic Island: start, stop, and log from your phone or widget • Privacy first design for families (see moonbow.app/privacy) APPLE WATCH COMPANION When reaching for your phone is not an option, start the Support Timer from your Apple Watch. Tap to begin, stop when the moment passes, and rate intensity on your wrist. Moonbow hands off to your iPhone so you can finish logging with LUMI. Your timer stays in sync with the app, lock screen widget, and Live Activity. PATENT PENDING EPHEMERAL PRIVACY We never store your voice or video. Moonbow uses a patent pending "ephemeral engine" that instantly translates your walkie talkie voice dumps into clinical text, and then permanently destroys the audio within milliseconds. You get the insights, with zero digital footprint. MOONBOW PREMIUM Try full Premium free for 14 days, then subscribe monthly or annually. Premium unlocks unlimited voice with LUMI, full history, Care Circle invites, clinical PDF export, clinician sync, and Prepare practice runs (environmental forecasts and home rehearsal). Cancel anytime in your App Store subscription settings. WHO IT'S FOR Parents and caregivers supporting autistic and neurodivergent children, especially families working with ABA, speech, OT, school teams, or private therapy. Moonbow does not replace professional diagnosis or emergency care. Prepare simulations are predictive planning estimates to help you set up your environment. They are not medical advice. You are the expert on your child. LUMI helps the care team hear you clearly.
