Growth chart
Weight, length, and head size against WHO reference ranges.
What it does
The Growth studio compares your baby's measurements — sex, age 0–36 months, weight (kg), length/height (cm), and optional head circumference (cm) — against WHO reference ranges and reports percentile buckets. Every result can be added to a Growth Measurement Log kept on your device, synced with a partner or pediatrician by link or QR, exported as CSV, and summarized in a printable Pediatrician Growth Summary. The tool's framing is careful: percentiles are a general statistical reference and illustration, not a clinical diagnosis.
Who it’s for
Parents who leave each weigh-in wondering what "60th percentile" actually means — and anyone tracking a growth curve over time.
How to use it, step by step
- Enter sex, age in months, weight, length, and (optionally) head circumference.
- Tap Show Growth Buckets for the percentile picture.
- Add the measurement to the Growth Log to build the curve over time.
- Share with your partner or pediatrician via link or QR; print the summary for visits.
- Export CSV if you want the raw numbers elsewhere.
What you get
Percentile buckets for weight, length, and head circumference, plus a saved measurement log and printable summary.
✦ A worked example
You give itAge 6 months, 7.5 kg, 67 cm, head 43 cm.
You getThree percentile buckets and one new point on the log — the curve, not just the dot, ready for the 6-month visit conversation.
💡 Tips & tricks
- The curve matters more than any single point: log every measurement and let the trajectory do the talking.
- A percentile is a ranking among peers, not a grade — 15th and 85th are both ordinary places for a healthy baby to live.
Enough reading — the tool itself is one tap away, and it is free.
