Grandstepper vs Go Tall

An app for grandparents to see their steps in big text

Understand your height potential without hype. Go Tall turns your measurements, family heights, growth history, sleep, nutrition, and posture into an educational range and a practical daily plan. YOUR REALISTIC RANGE Build a broad, transparent estimate using the conventional mid-parental method and your self-reported growth history. See the uncertainty—never a fake guarantee. THE FACTORS YOU CAN CONTROL Follow daily actions for consistent sleep, balanced nutrition, mobility, posture, and accurate measurement. Go Tall separates biological growth from the standing height and presence you may gain through better alignment. POSTURE CHECK Use an optional photo for an on-device Apple Vision posture check. Your photo stays on your iPhone and is never uploaded. TRACK REAL PROGRESS Log consistent measurements, review trends, and avoid mistaking normal day-to-day variation for growth. OPTIONAL AI COACH Premium includes a consent-based AI coach for questions about your plan. Only the profile details and question you choose are sent; photos are never sent. Go Tall is an educational wellness tool, not a medical device. It cannot predict final adult height with certainty, diagnose conditions, or make anyone taller. Growth varies, and concerns about development should be discussed with a qualified clinician. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
