Is your baby on track? A CDC-based milestone checklist filtered to your child's exact age — log the date and the story of every first, from first smile to first steps. Is your baby on track? Milestone gives you the answer the way a pediatrician would: an age-appropriate checklist of developmental milestones, built on the CDC's 2022 milestone guidance and filtered to exactly your child's stage — from first smile to short sentences, ages 0 to 3. Most milestone lists dump all 24 skills on you at once. Milestone reads your child's age in months and shows only what typically appears at this stage, what is coming next, and the window each skill usually opens in — always a range, never a deadline. When a first happens, you tap it, date it, and write down the story of the moment, so "first steps" stays a memory instead of just a checkmark. WHAT YOU GET • Open the app and see exactly which milestones fit a 7-month-old today — no scrolling past toddler skills • All four areas of development — Motor, Social, Language, and Cognitive — each with typical CDC-based age windows • "Coming up" shows the next three milestones before they happen, so you know what to watch for • Every first is saved with its date and your note about the moment — waving bye-bye at the beach stays remembered • A gentle reminder when a new milestone window opens for your child — never a "your child is late" alarm • A progress overview across all four areas, with room for every child in the family PERFECT FOR • First-time parents who keep searching "what should my baby be doing at this age" • Parents heading into a well-child visit who want dated notes to discuss with the pediatrician • Families with two or more kids under 3 who want one place for everyone's firsts • Caregivers and grandparents who want to know what stage the little one is in right now WHY NOT JUST A PAPER CHECKLIST? Paper doesn't know your child's age. Milestone recalculates the relevant window every day, nudges you when a new one opens, and keeps the date and story of each first — things a fridge printout will never do. Every child develops at their own pace; Milestone is a guide for conversations with your pediatrician, not a diagnosis. PRIVATE BY DEFAULT Everything stays on your iPhone. No account, no cloud, no tracking — the app never asks for your camera, photos, location, or contacts. Your child's name and birthday never leave the device. FULL ACCESS Milestone requires a purchase, which unlocks everything: the full CDC-based checklist across all four areas, milestone logging with dates and stories, milestone-window reminders, the progress overview, and unlimited children. Choose a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Download Milestone, enter your child's birthday, and see this week's milestones in under a minute.
