Child Growth Tracker

Child Growth Tracker helps parents record and visualize their child's
height, weight, and BMI over time — compared against standard
growth percentile charts.

📊 KEY FEATURES

- Growth Charts with Percentiles
Compare your child's measurements against standard growth curves
(P3 ~ P97). See exactly which percentile your child falls in for
height, weight, and BMI.

- Easy Data Entry
Enter height and weight by date. BMI is calculated automatically.
You can save with just height or just weight.

- Interactive Charts
Pinch to zoom, drag to pan. View all three charts at once or
focus on a single metric.

- Data Stored Locally
All data is stored privately on your device. Nothing is sent to
external servers without your consent.

- Backup & Restore
Export your data as a JSON file to save to cloud storage or
transfer to a new device. Restore anytime from a backup file.

- Multiple Child Profiles
Register multiple children and track each one separately.

🌍 LANGUAGE SUPPORT
Automatically displays in Korean or English based on your device language.
