Quick answers
How do I add my child?
Open the app → tap + Add Child on the home screen → enter name, date of birth, country, and (optionally) state or province. The free tier supports one child profile; Premium unlocks tracking for additional children.
How do I record a vaccine?
Open a child's profile → tap Add multiple records → pick the vaccines given, the date, and optional details like provider or lot number. Records are saved to your device.
Why is a vaccine showing as overdue?
The schedule comes from the official health authority for the country you selected for that child (CDC for US, NHS for UK, MoHFW for India, etc.). If a recommended dose is past its due window with no record, it shows as overdue. Add the record and the status updates.
How do reminders work?
Reminders are scheduled on your device only - no servers involved. Enable them in Settings → Notifications. You'll be reminded ahead of upcoming doses and again if a dose becomes overdue.
What does Premium unlock?
The Premium one-time purchase unlocks:
- Multiple children - track every kid in your family on one device
- QR Profile Transfer - share or receive a child profile with another parent
- Ask About Vaccines - quick answers about vaccine schedules and your records (works offline)
- PDF Export - save vaccine records to share with doctors
- PDF Import - restore records from a previous export
The free tier (one child, full schedule, reminders, overdue alerts, photo attachments, all status views) is included at no cost, with no ads.
How do I restore my Premium purchase on a new device?
Open the app → Settings → Restore Purchases. As long as you sign in to your new device with the same store account you used to purchase, your Premium unlock will be recognized.
How do I back up my data?
Settings → Backup Data creates a JSON file you can save anywhere (email it to yourself, save to Files, AirDrop, etc.). On a new device, install the app and use Settings → Restore Data to load the backup.
How do I share a child's profile with another parent?
QR Profile Transfer is a Premium feature. On a Premium account, open the child's dashboard → Share Profile, which generates a QR code. The other parent opens the app, taps Import via QR (Settings → Import via QR - also Premium), and scans. The profile transfers directly between devices - nothing goes through any server.
Does the app work offline?
Yes - completely. Every feature, including the Premium Ask About Vaccines chat, runs on your device. The app makes no external network calls.
How do I delete my data?
Settings → Delete All Data wipes every child profile, every record, and every photo from your device. There's no cloud copy to delete because the app never had one.
