Child Growth Tracker does one thing beautifully — it plots your child's weight, height, and head circumference on clinical growth curves. Family Stork tracks growth too, but inside a timeline that also holds checkups, vaccines, allergies, milestones, and every other record your child will need. Here's where each one fits.
Child Growth Tracker is a dedicated growth charting app. It supports WHO, CDC, and a dozen other international growth standards. It handles corrected age for preterm babies, generates PDF reports for doctor visits, lets you export CSV files, and plots multiple children on the same chart. It's made by a parent who needed accurate percentile curves and built exactly that.
Family Stork is a lifelong family health timeline. Growth measurements land on the timeline alongside everything else — the checkup where they were recorded, the vaccines given that day, the allergy flagged a month later. One chronological record from birth, across every provider, with AI that organizes it and lets you ask questions about your child's history.
Accurate LMS percentile method. Clinical-grade calculations using the same method pediatricians use — not simplified percentile buckets.
Corrected age for preemies. Gestational age adjustment built in — critical for premature babies whose growth curves look different in the first two years.
Dozens of international charts. WHO, CDC, Swedish, Spanish, and more. If your pediatrician uses a specific standard, it's probably there.
PDF reports. Generate a clinical-looking growth report you can share with your doctor or bring to appointments.
CSV import/export. Move data in and out easily. No lock-in.
Multiple children on one chart. Compare siblings' growth patterns side by side.
Growth inside the timeline. Height, weight, and head circumference live alongside the checkup where they were measured — not in a separate app.
One record, all providers. Records from every clinic, hospital, and specialist. Growth data doesn't exist in isolation — it's part of the whole picture.
Records-inbox email. Clinics send visit summaries directly. The timeline files them, including growth measurements from the visit.
Paper capture. Snap a photo of the growth chart from the pediatrician's office. The AI reads and organizes the data.
Ask anything. "When did she drop below the 25th percentile?" or "What happened at the 9-month checkup?" The record answers.
Birth-to-18 handoff. The complete record — growth and everything else — transfers to your child when they're ready.
Your pediatrician says your toddler's weight has dropped two percentile lines. You need the full history — not just the chart, but what was happening at each visit. Was she sick? Did you switch formulas? When did the trend start? Growth data without medical context is just a line on a graph.
Your new doctor asks for growth history. A CSV file from a charting app shows the numbers. A complete timeline shows the numbers plus the context — the allergist referral at 14 months, the formula change at 8 months, the ear infection that coincided with a weight plateau.
An endocrinologist wants to see growth history alongside other health data. They don't just want a percentile curve — they want to know what else was going on. Medications, lab work, developmental milestones. That's a health record, not a growth chart.
If your main goal is plotting percentiles accurately — especially if you need corrected age curves for a preemie or specific international standards — Child Growth Tracker is purpose-built for that.
If you want growth data to be part of a larger record that holds everything about your child's health — and you want to be able to search it, share it with new doctors, and hand it to your kid one day — that's a different tool for a different job.
Some parents use both: Child Growth Tracker for the detailed charting experience, and Family Stork for the complete record that ties it all together.
Growth measurements, checkups, vaccines, allergies, milestones — one record from birth.
