LittleGrowth — Growth Charts

See exactly where your child sits on trusted international growth curves — instantly, privately, entirely offline. No account. No ads. Pay once, yours forever.

Log your child's height, weight, and head circumference — and see instantly where they sit on trusted international growth percentile curves.

Built on the internationally recognized child growth standards pediatricians use worldwide, with percentile math verified against the published reference values.

No account. No cloud. No ads. No subscription. No tracking. Your child's data never leaves your phone.

HOW IT WORKS Add a child profile (name, birthdate, sex — photo optional). Enter a measurement, and LittleGrowth immediately shows the percentile — for example "P62 height, P48 weight" — plus a plain-language line like "growing steadily along their curve". Every measurement is plotted on growth curve-band charts (P3 / P15 / P50 / P85 / P97), so you can see your child's own curve take shape over time, from birth to age 5.

WHAT IT DOES • Instant growth percentiles for height/length, weight, head circumference, and BMI-for-age • Beautiful growth curve-band charts with your child's measurements plotted on them • Multiple children, each with their own profile and history • Summary cards showing the latest numbers at a glance • cm/in and kg/lb — switch anytime • Works fully offline, everywhere, always • One-time purchase. Yours forever.

WHAT IT DOES NOT DO • It does not require an account, login, or any personal information • It does not send data anywhere — there is no server, no cloud, no sync • It does not contain ads, analytics, trackers, or third-party SDKs • It does not judge. A percentile is a statistical position among healthy children, not a verdict on your child's health. LittleGrowth will never label a number "good", "bad", "normal", or "concerning", and never suggests what to do about it.

PRIVATE BY ARCHITECTURE Everything is stored in a local database on your device. The app has no network layer at all — there is nothing to leak, nothing to breach, nothing to subpoena. Delete the app and the data is gone. That's the whole privacy policy, and it's enforced by design, not by promise.

ABOUT THE DATA LittleGrowth is built on internationally recognized child growth standards (birth to 5 years) that are in the public domain and bundled inside the app. Percentiles are computed with the standard LMS method, and the math is unit-tested against the published reference values.

IMPORTANT — PLEASE READ For information only — this app is a tracker, not medical advice. Always consult your pediatrician. LittleGrowth is an informational tracking tool. It is not a medical device and does not provide medical, diagnostic, or health advice, screening, or recommendations of any kind. Growth is highly individual, and only a qualified pediatrician or doctor can interpret your child's measurements in context. For any health decision or concern, talk to your doctor. Do not use this app in an emergency.
