goTall - Support & Help

Simply open goTall, tap the "+" or "Add Measurement" button, enter your current height with the date, and save. The app will automatically start tracking your growth journey and creating visualizations.

Height predictions are estimates based on statistical models using your age, current height, gender, and family height data. While our algorithm uses scientific methods, actual height is primarily determined by genetics and may vary. Predictions should be used for informational purposes only, not as medical advice.

Our games are designed to promote activities that support healthy growth:

• Jump Challenge: Builds leg strength and may stimulate growth plates
• Posture Perfect: Improves posture, making you appear taller instantly
• Stretch Master: Increases flexibility and spinal decompression
• Growth Sprint: High-intensity exercises that boost growth hormone naturally

Remember: These activities support overall health but cannot change your genetic height potential.

Posture Perfect uses your device's camera to detect your body position:

• Allow camera access when prompted
• Position your device so it can see your full body
• Stand in front of the camera and follow on-screen instructions
• The app will analyze your posture and provide real-time feedback
• Complete challenges to improve your posture score

Privacy Note: Camera data is processed locally on your device and never stored or uploaded.

Growth challenges are daily and weekly tasks designed to support healthy development:

• Nutrition challenges (drink water, eat protein-rich foods)
• Sleep challenges (get 8+ hours of quality sleep)
• Exercise challenges (complete stretches, jump exercises)
• Posture challenges (maintain good posture throughout the day)
• Consistency challenges (track measurements regularly)

Complete challenges to earn points, unlock achievements, and build healthy habits!

We recommend measuring your height:

• Weekly: For active growth periods (teens 13-18)
• Bi-weekly: For slower growth phases
• Monthly: For tracking long-term trends

Measurement Tips: Measure at the same time of day (morning is best), use the same surface, stand straight with heels against the wall, and measure barefoot for consistency.

goTall helps you maximize your natural height potential through:

• Tracking growth patterns to identify progress
• Posture improvement (can add 1-2 inches to appearance)
• Exercise routines that support healthy bone development
• Habits that optimize natural growth hormone production

Important: Height is primarily determined by genetics. goTall cannot change your genetic potential but helps you reach it through healthy habits and optimal posture.

While genetics determine most of your height, you can optimize growth through:

• Exercise: Regular stretching, jumping, swimming, and sports
• Posture: Practice good posture to maximize your existing height
• Avoid growth inhibitors: Don't smoke, limit caffeine, avoid excessive stress
• Stay active: Use goTall's games and challenges daily

Remember: These habits support overall health and help you reach your genetic potential, but cannot change your predetermined height.

goTall's exercises and games are designed for general fitness and are safe for most healthy teens and young adults. However:

• Warm up before exercises and cool down afterward
• Use proper form as demonstrated in the app

Consider consulting a healthcare provider if:

• You're concerned about slower than expected growth
