The growth chart is free now: CDC percentiles, stretch routine, unlimited entries. Only the height projection is paid, once, not a subscription.
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 to set up. The app uses anonymous usage analytics (screen views, feature taps) to see what's working — no ads, no data sold. 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.
