Height Predictor for Teens
Read full descriptionHide full description
Put in your age, your height and how tall your mom and dad are, and it works out roughly how tall you'll be when you stop growing. You get a number plus a range, since nobody can know your exact final height. It uses the CDC height-for-age growth charts blended with your parents' heights (the mid-parental thing pediatricians do). I put a screen in that goes through the math step by step and linked every source, so you don't have to take my word for it. Your dot goes on the CDC percentile chart, so you can see what percent of kids your age you're taller than. Measure every few months and log it. If you're mid growth spurt the line shows it. There's a stretch section for posture with drawings and a timer, and a daily check-in for sleep and food. Stretching doesn't make bones longer. Standing straight still adds a surprising amount to how tall you look in photos though. Height maxxing people: this is the bit that tells you what you're starting from. The questions and the chart are free. Seeing your predicted height is a single purchase, I didn't want to do a weekly subscription like the other height apps. No account, what you type stays on your phone and Delete in settings wipes it. Late bloomers exist and plenty of people end up a few cm off any prediction. If your growth actually worries you, see a doctor. Works in cm or ft/in, ages 2 to 20.
