Stays on this device. Add a child, log measurements as they grow. Track height, weight, head circumference (under-2s) over time. Approximate CDC/WHO percentiles shown for the latest entry. Not a clinical tool — always cross-check with the pediatrician.

ChildrenUnits

Add a child to start tracking. You'll need their date of birth to compute age-based percentiles.

About the percentiles. These are approximations against the WHO Child Growth Standards (0-2 years) and CDC growth charts (2-20 years), interpolated from anchor ages. They're useful for spotting trends — a kid who's been ~50th percentile and suddenly drops to ~10th deserves a conversation with their pediatrician. They are not a substitute for a clinical chart plotted by your provider's full LMS reference.

About Kids Growth Tracker

Track your child's height, weight, and head circumference over time. Plots a growth curve against approximate WHO/CDC P5/P50/P95 percentile bands. Multi-child, all on-device.

WHO Child Growth Standards (0-2 years) and CDC growth charts (2-20 years) are the gold-standard references for paediatric growth tracking. Pediatricians plot every visit's measurements against these to spot trends — a kid who's been ~50th percentile and suddenly drops to ~10th deserves a closer look.

This is a parent-facing rough figure, not a clinical lookup. The percentiles are interpolated from anchor ages — useful for spotting trends, not for replacing your provider's full LMS reference. Multi-child, log weight / height / head circumference, plot the line against the percentile band.
