Height & Growth Intelligence
Track every measurement, understand your growth curve, explore adult-height estimates and see the bigger picture with evidence-based growth intelligence.
Why GrowTall exists
Height is shaped by genetics, development and time — not miracle hacks. GrowTall helps you measure what is actually happening, understand the trend and keep a reliable record as growth unfolds.
WHO and CDC growth standards
Guided age-appropriate protocols
Ranges, not guarantees
Your entered growth records stay local
No pills. No gimmicks. No fake promises.
Your growth story
A single height tells you where you are.
A history shows where you’re going.
See the curve
Plot real measurements against established age- and sex-specific growth references and see how the trajectory changes over time.
Percentile curves are population references — every child follows their own healthy path.
Velocity under 14 days apart is normalized to avoid misleading spikes — slow, steady change is what matters.
Population references provide context — every person follows an individual growth path.
Know where you are
Percentiles become far more useful when viewed as a trajectory rather than a single score.
A percentile is a location, not a grade. What matters most is growing steadily along your own curve — which is exactly what GrowTall is built to show.
Look ahead
Explore evidence-based adult-height estimates using the information available in your growth profile.
A genetic corridor calculated from biological parental heights, shown with its natural ±8.5 cm variation.
A validated research method using age, current height, weight and parental heights — no bone-age X-ray required.
Results appear as ranges because genetics, puberty timing and individual development create natural variation.
Predictions are estimates, not guarantees. Genetics, puberty timing and individual development create natural variation.
Explore your growthMeasure better
GrowTall changes its guidance based on age, so infant length and standing height are recorded with the appropriate protocol.
GrowTall switches protocols automatically based on the profile’s age.
Healthy development
Track everyday behaviors that support general health, development and wellbeing.
Restorative sleep and consistency
Movement, play and weight-bearing activity
Protein, calcium, colorful foods and balanced meals
Simple daily water tracking
Movement and spinal mobility routines
Each habit takes seconds to log, builds a streak over time and appears in your growth summaries — useful context for the whole family and for pediatric visits.
Healthy habits support general health and normal development. They do not override genetics or guarantee increased adult height.
Understand the science
Learn what actually influences growth, what does not, and when a changing growth pattern may be worth discussing with a healthcare professional.
Why parental heights set a statistical corridor — and why real people land inside, not on, the average.
PubertyPeak height velocity, timing differences, and what a “normal” spurt range looks like.
TrackingStandard stadiometer protocol and why time of day shifts your number.
HealthPatterns that are typically reassuring — and the signs pediatricians check for.
SleepHow deep slow-wave sleep aligns with the body’s natural hormone rhythm.
PostureWhy mobility and alignment improve standing stature without changing skeleton.
NutritionProtein, calcium, vitamin D and overall caloric adequacy work together.
One app. The whole family.
Track multiple children or family members without mixing histories. When pediatric references no longer apply, GrowTall automatically transitions adult profiles into tracking mode.

Balanced sleep, daily activity and consistent nutrition logging.

From your phone to the checkup
Turn recorded growth history into a clean consultation summary that is easier to discuss during routine pediatric visits.
The summary is a conversation aid — it is not a diagnosis and does not replace professional evaluation.
Private by design
GrowTall stores profiles, measurements, habit logs and notes locally on your Android device. We do not sell health information or build advertising profiles from your growth data.
Ever. The free app is the whole experience.
Growth records are never a product.
Your database lives on your device.
Coarse reliability events only — off anytime in settings.
GrowTall uses limited third-party infrastructure for app reliability, app integrity and Google Play subscription functionality. Entered heights, weights, notes and habit values are not sent to our analytics services.
Android device backup may include the local database when system backup is enabled.
Core growth tracking stays free. GrowTall Plus unlocks advanced tools for families who want more.

Built on established references
GrowTall converts established growth-reference methods into understandable, longitudinal insights — without presenting estimates as diagnoses or guarantees.
International standards for children from birth to age 2, based on healthy growth environments.
National reference curves for height- and weight-for-age from 2 to 20 years.
Body-composition context when optional weight measurements are recorded.
A validated non-invasive method for projecting adult stature in healthy children.
Questions, answered
A height percentile shows how a measurement compares with a reference population of the same age and sex. Being at the 33rd percentile means a measurement is taller than about 33 of 100 children and shorter than about 67. It is a location on a population curve, not a grade — steady growth along any percentile channel is generally a healthy sign.
For meaningful trends, measure every 60 to 90 days using consistent conditions — same time of day, barefoot, against a flat wall. Natural height varies by roughly 1–1.5 cm during the day, so frequent measurements mostly capture daily fluctuation rather than true growth.
GrowTall does not claim to increase genetically determined adult height. It helps you accurately track growth, understand established growth references, follow healthy development habits and explore evidence-based height estimates.
GrowTall uses established reference methods available in your growth profile — the mid-parental target height based on biological parental heights, and the Khamis-Roche model when age, current height, weight and parental heights are available. Results are always presented as ranges that reflect natural variation, not single guarantees.
Khamis-Roche is a validated research model for predicting adult stature without bone-age X-rays. It uses a child’s age, current height and weight together with biological parental heights. Like all prediction methods, it carries natural variation, so GrowTall shows its result as a corridor.
Yes. GrowTall supports multiple family profiles, each with its own measurement history, reminders, habit logs and growth insights, so histories are never mixed.
Yes. When pediatric growth references no longer apply, GrowTall automatically transitions a profile into adult tracking mode, which continues to record height history and healthy habits without percentile comparisons.
Profiles, measurements, habit logs and notes are stored locally on your Android device. GrowTall does not sell health information or build advertising profiles from it. The app uses limited third-party infrastructure for reliability, app integrity and Google Play subscription functionality, but entered heights, weights, notes and habit values are not sent to analytics services. Android device backup may include the local database when system backup is enabled.
GrowTall Plus is an optional upgrade that unlocks adult-height estimates, Khamis-Roche and mid-parental prediction ranges, pediatric consultation summaries, measurement reminders, habit consistency analytics, guided mobility routines, and backup and restore. Core growth tracking stays free.
GrowTall provides growth tracking, population-reference information, estimates and general wellness education. It is not a medical device and does not diagnose, treat, cure or prevent medical conditions.
Measurements become milestones.
Milestones become a trend.
GrowTall helps you understand the story.
