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.

VitalFill turns nutrition into something you can see. Log what you ate. Pick any nutrient — vitamin D, iron, magnesium, leucine. A human figure fills up to show exactly how much of YOUR daily need you've covered. Not a generic label percentage. Yours. WHY IT'S DIFFERENT Most trackers count calories and stop there. VitalFill asks what actually matters: are you getting enough of what your body needs? Free, your targets are the standard FDA reference — the same numbers on a Nutrition Facts label. Upgrade and they switch to your own numbers, calculated from NIH Dietary Reference Intakes using your age, sex, height, weight and activity level, and adjusted for pregnancy or breastfeeding. Two people logging the same meal can then see different results, because their needs differ. FOUR WAYS TO LOG • Search — over two million foods from the USDA FoodData Central database • Barcode — scan any packaged product, unlimited and free • Photo — snap your plate and let AI identify it (1 free scan/day) • Voice — just say "two eggs and a slice of toast" (3 free logs/day) WHAT YOU CAN TRACK Calories, protein, carbohydrates and fats — including saturated, monounsaturated, polyunsaturated and cholesterol. Every vitamin from A to K. Every essential mineral. All nine essential amino acids. Fiber and sugars. Every one of these is free — see below. BUILT FOR PRIVACY No account. No sign-up. No email address. We never ask who you are. Your profile and food log stay on your device — we hold no copy. Voice logging transcribes speech on your phone; no audio ever leaves it, only the resulting text is sent for parsing. Photo and recipe scanning send the photo to Anthropic's Claude API for recognition only; it's never stored. There are no ads, no analytics, and no tracking of any kind. SEE THE WHOLE PICTURE • Daily status for any nutrient, as a filling figure • Coverage view showing every nutrient at once • Biggest gap — what you're most short of today • Which foods contributed what • Look back at any previous day DATA SOURCES Nutrient values come from USDA FoodData Central. Daily targets come from NIH Dietary Reference Intakes. Every nutrient links to its source. VITALFILL FREE Every nutrient, every score, unlimited barcode scanning, one AI photo scan a day, and 3 voice logs a day — all measured against the standard %DV reference. No nutrient or score is hidden behind a paywall; only personalization is. VITALFILL PRO Pro switches your score and every target from the standard reference to numbers calculated from your own age, sex, weight and activity level. It also adds: • Scan any recipe or ingredient list and get a nutrient density score for the whole dish • Save a favorite meal once, log it again in one tap • Full history and 30-day trend charts, by day or by individual meal • 14 photo scans a day and 60 voice logs a day (vs. 1 and 3 free) SUBSCRIPTION DETAILS • VitalFill Pro Annual — 1 year, with a 3-day free trial • VitalFill Pro Lifetime — one-time purchase, no subscription, ever Annual: payment is charged to your Apple ID account at confirmation of purchase.
