Turn three visits into a trend
Enter each visit with its original measurement date, save it, then switch between weight, length or height, head circumference, weight-for-length and BMI views. A trend is more informative than copying today’s date onto older measurements.
What one point and several points tell you
| View | Useful for | Do not assume |
|---|---|---|
| Single measurement | A reference comparison on one date. | That one point defines a growth pattern. |
| Saved history | Seeing how consistently measured observations change. | That the chart diagnoses the reason for change. |
| Dotted reference line | Orientation at the latest percentile. | That it predicts future size. |
Build a cleaner record
- Use the original date and the method appropriate for age: lying-down length under two, standing height from two.
- Keep units and measuring conditions consistent; repeat an unexpected measurement.
- Use Backup file before clearing browser data or moving devices.
Privacy and portability
Nothing is uploaded to an application account. You can print a readable summary, export a spreadsheet-friendly CSV, or create a JSON backup that can restore the local record.
Questions parents ask
Where is growth history stored?
Only in this browser’s local storage after you choose Save measurement. There is no account or cloud database.
Can I move the history to another device?
Yes. Download a backup JSON file on the first device and restore it on the second. Restoring replaces the current local record only after confirmation.
Does the dotted chart line predict future growth?
No. It shows future reference values at the latest percentile as orientation only; it is not a forecast.
