When writing about an issue, it helps to include: your Android version, whether you use metric or imperial, and a short description of what you saw versus what you expected.
Getting started
- Create a profile — Family → Add member. Name, date of birth, sex and units set the right growth references and protocols automatically.
- Record a measurement — Home → Record Measurement, and follow the guided protocol for the profile's age (standing height 2+, recumbent length under 2).
- Read the chart — Growth tab shows the height curve, percentile view and velocity. See child growth charts for a walkthrough.
- Log habits — Habits tab tracks sleep, activity, nutrition, water and posture in seconds a day.
GrowTall Plus
Plus unlocks adult-height estimates (mid-parental and Khamis-Roche), pediatric consultation summaries, measurement reminders, habit analytics, guided mobility routines and backup & restore. It is billed through Google Play — to manage or cancel, open Google Play → Payments & subscriptions → Subscriptions. Uninstalling the app does not cancel a subscription.
Your data
Everything you enter stays on your device. Optional anonymous analytics cover coarse reliability events only and can be switched off in Family → Privacy & Local Data. If Android system backup is enabled, your local database may be included in device backups. We never see, sell or profile your growth records. See our methodology and terms for the fine print.
Common questions
- Why does the app ask for the time of day? Height varies 1–1.5 cm between morning and evening; tagging keeps trends clean. See how to measure height.
- Why is velocity "unavailable"? Measurements less than 14 days apart are normalized to avoid fake spikes — measure every 60–90 days.
- Can two children share a phone? Yes — that is what family profiles are for. Each keeps separate history, reminders, habits and insights.
- Does GrowTall work for adults? Yes — profiles transition to adult tracking mode automatically when pediatric references no longer apply.
