Immunization Record Tracker

Read full description

Your child's vaccine schedule, tracked. ChildVaccs is a baby vaccine tracker and vaccination record built for parents: it pre-loads the US routine childhood immunization checklist from birth through age six, shows exactly which dose sits in its window at your child's age today, and reminds you a week before the next one opens. No accounts, no clinic portal, no spreadsheet. Enter a birthday once and the full series — Hepatitis B, Rotavirus, DTaP, Hib, PCV, Polio, MMR, Varicella, Hepatitis A and yearly flu — arranges itself into an age-organized record book. Log the date each dose was given, keep the clinic and lot number with it, and watch the completion seal climb toward 100%. WHAT YOU GET • Open the app the week your toddler turns 15 months and "DTaP Ā· Dose 4 — ready to review" is already waiting • A reminder 7 days before a dose window opens, so the appointment is booked before it is due • Every logged shot keeps its date, clinic and lot number — answers ready the moment a school form asks • A catch-up flag when a dose slips past its routine window, with a link to published catch-up guidance • One clean PDF of the whole record to hand to daycare, school or a new pediatrician • A separate record book per child, each one's progress visible on a single family desk PERFECT FOR • New parents facing the dense first-year run of 2, 4 and 6-month visits • Families with two or more kids at different points on the timeline • Parents switching pediatricians or enrolling in daycare who need the record in hand • Anyone whose paper immunization card has become a coffee-stained mystery WHY NOT JUST THE PAPER CARD? The card stays home the day the school form is due, fades with every year, and never reminds you of anything. State registry apps only work where your clinic participates. ChildVaccs lives on your phone, watches the calendar for you, and prints a fresh copy any time. PRIVATE BY DEFAULT Every record stays in on-device storage. No account, no cloud upload, no tracking — reminders are local notifications scheduled on your phone. Delete a profile and it is gone. ChildVaccs is a record-keeping reference aligned with the routine US childhood schedule. It is not medical advice — always confirm vaccines, products and timing with your child's clinician. FULL ACCESS ChildVaccs Pro unlocks the complete app: unlimited child profiles, the full birth-to-six checklist with reminders, and PDF record export. Choose an auto-renewing Weekly or Yearly subscription, or a one-time Lifetime purchase. Subscriptions renew unless cancelled at least 24 hours before the current period ends and can be managed in your App Store account settings. Add your child's birthday today — the next dose window is already on the checklist.
