TallPlan is a height predictor and growth tracker for teens.

TallPlan helps you answer: • How tall will I be as an adult? • Am I still growing? • How much have I grown since I started? • How much sleep, protein and calcium do I need for my age? 1. Start with your height prediction TallPlan's height calculator starts with the mid-parental height formula, which predicts height from your parents' heights, and also considers: • Tall relatives in your family • Your age, sex and current height • Signs of puberty You get an adult height estimate with a predicted range, not just a single number. 2. Build your daily growth plan Want to grow taller? Genes set your range. Daily habits support healthy growth within it, through growth spurts and the rest of your growing years. Your personal growth plan includes: • Sleep: a sleep goal for your age • Protein: a target based on your body weight • Calcium: a target for your age • Exercise: daily workouts for posture and core Targets follow published guidelines, including those from the American Academy of Sleep Medicine and the US Dietary Reference Intakes. 3. Work on your posture and core Slouching can hide part of your height. Short daily workouts made for teens build core strength and better posture, so you stand straight at your full height. 4. Log meals with a photo or text Snap a photo of your meal or describe what you ate. TallPlan estimates its protein and calcium so you can log your daily nutrition without looking up every food. 5.
