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.

Like every tool on Buncha, this one runs entirely in your browser. There's no upload, no log, no record of what you've pasted or generated. Close the tab and the data is gone.
