Height Predictor - Heightcast Live

How tall will your kid end up? You put in their age, sex and current height, plus both parents' heights, and Heightcast works out an adult height estimate with a range around it. It finds where your child sits on the CDC stature-for-age growth chart and blends that with the parents' heights. If you want to check the math there's a screen that walks through it, and every source is linked in the app (the CDC charts and the papers behind each step). The chart shows your kid's dot on the percentile lines and where the curve is probably headed. Log a new height a couple times a year and watch it fill in. There's also a daily checklist for sleep, food, activity and posture, and a few stretch routines with drawings of each move. Those are for posture and mobility, they won't change adult height. Works in cm or feet/inches. No account to make. The heights and birthdays you type in stay on your phone, and the delete button in settings really does delete them. The questions are free. Seeing the estimate, the chart, the log and the habits is one in-app purchase, paid once, no subscription. The Android version is newer than the iPhone one, so if something looks wrong on your phone please email [email protected] and I'll fix it. Please treat it as an estimate. If your child's growth worries you, talk to your pediatrician.
