Height Predictor vs Sumki

Estimates a child's adult height from the CDC stature-for-age charts plus both parents' heights. Shows a range, the percentile chart with your kid's dot on it, and the math behind the number. Every source is in the app. A Sources & references screen lists the CDC growth charts, the published papers behind the percentile and mid-parental steps, and the guidance behind each daily prompt, each one linked and saying which part of the app it backs. Log height a few times a year to follow the curve. There's a daily habit checklist and guided stretch routines with illustrated demos. Stretching is for posture and mobility; it does not change adult height. Works in cm or ft/in. Runs entirely on your phone. No account, no server, no analytics, no ads. Deleting your data in settings removes it completely. Heightcast is an estimate built from public growth references. It is not a diagnosis, not a medical device, and not a substitute for a pediatrician. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
