GrowTall: Height Tracker

How tall are you growing — and where is your growth headed?

GrowTall is an evidence-based height tracker and family growth app for recording height, understanding growth percentiles, estimating adult height, and following healthy development over time.

Whether you're looking for a height tracker, child growth chart, height prediction, or a better way to understand growth, GrowTall replaces guesswork with real measurements and established WHO and CDC growth references.

TRACK HEIGHT OVER TIME

Record height or length with a guided measurement process designed for consistent results.

• Metric and imperial measurements
• Standing-height guidance for ages 2+
• Recumbent-length guidance for children under 2
• Morning and evening measurement tags
• Measurement quality indicators
• Optional weight tracking
• Complete measurement history

WHO & CDC GROWTH CHARTS

See recorded measurements against established pediatric reference curves.

View growth trajectory, percentile channels, and growth velocity instead of relying on a single measurement.

HEIGHT PERCENTILES

Understand where a recorded height falls compared with age- and sex-specific reference populations.

GrowTall emphasizes trends rather than labels. A child can develop normally across many different percentile channels; consistency over time is often more useful than any single percentile.

ADULT HEIGHT ESTIMATES

Curious how tall you or your child may eventually be?

GrowTall provides two evidence-based reference methods when the required information is available:

• Mid-parental target height based on biological parental heights
• Khamis-Roche adult stature prediction using age, current height, weight, and parental heights

Predictions are shown as ranges, not guarantees. Genetics, puberty timing and individual development create natural variation.

PEDIATRIC BMI-FOR-AGE

For ages 2–20, GrowTall uses age- and sex-specific CDC BMI references instead of applying adult BMI thresholds to children.

BMI classification is unavailable when the appropriate pediatric reference cannot be applied.

HEALTHY DEVELOPMENT HABITS

Track everyday habits associated with general health and normal development:

• Sleep
• Physical activity
• Balanced nutrition
• Hydration
• Posture and mobility

These habits support overall health and development. They do not override genetics or guarantee increased adult height.

FAMILY GROWTH TRACKING

Create separate profiles for multiple family members and keep each person's measurements, habits, reminders, and growth history organized independently.

Adult profiles automatically switch to tracking mode when pediatric growth references no longer apply.

PEDIATRIC VISIT SUMMARY

GrowTall Plus can turn recorded measurements into a clear consultation summary containing height history, applicable percentiles, growth velocity, parental-height context, and explicitly recorded habit observations.

Share it during routine pediatric visits to make growth conversations easier.

MEASUREMENT REMINDERS

Growth happens slowly. Instead of encouraging daily measuring, GrowTall supports spaced check-ins such as every 60 or 90 days so real trends are easier to distinguish from normal day-to-day height variation.
