Bone Age Height Predictor

Features
Read full description

Bone Age Height Predictor is a focused clinical calculator for estimating predicted adult height (PAH) using the Bayley–Pinneau method, bone age, and pediatric growth inputs. Designed for pediatric endocrinologists, pediatricians, radiologists, orthopedic clinicians, and other healthcare professionals, the app supports the common workflow where skeletal age is already available and the next step is a tempo-adjusted adult height estimate. Enter bone age from a hand/wrist radiograph report or clinical assessment, and translate skeletal maturity into a practical height estimate in seconds. KEY FEATURES • Bayley–Pinneau prediction Uses bundled, offline, sex-specific tables to estimate predicted adult height from current height and skeletal age. • Growth tempo selection Choose Advanced, Average, or Delayed maturation to match the patient's growth pattern—an important Bayley–Pinneau variable that most consumer height apps omit. • Fast single-screen workflow Enter sex, growth tempo, current height, and bone age (years), tap Calculate, and review the result with a summary of the inputs used. • Sex-specific skeletal-age tables Separate lookup tables for boys and girls across clinically relevant skeletal-age ranges, with tempo-specific coverage. • Clear inputs and outputs Results display Predicted Adult Height alongside the sex, tempo, height, and bone age values used in the lookup. • Offline calculation Tables are bundled on-device—no network connection required for the core calculation. • Not a grow-taller or lifestyle app A professional calculation tool, not exercise, coaching, or height-hacking content. WHO IT IS FOR Bone Age Height Predictor is intended for healthcare professionals involved in pediatric growth evaluation, including: • Pediatric endocrinologists • General pediatricians • Radiologists • Pediatric orthopedic clinicians • Growth and puberty specialists • Medical trainees in pediatric endocrine settings IMPORTANT MEDICAL DISCLAIMER This app is a clinical calculation and reference aid for qualified healthcare professionals. It does not diagnose, treat, monitor, or prevent any disease or condition. It does not interpret radiographs, perform bone age scoring, or replace professional clinical judgment, radiology assessment, or individualized patient care. Predicted adult height estimates are approximations and should be interpreted alongside the patient's full clinical history, growth pattern, pubertal stage, family heights, exam findings, and applicable local standards of care.

BoneAge estimates a child's skeletal age from a hand X-ray in seconds — entirely on your device. BoneAge reads a hand/wrist X-ray the way radiologists do: it examines the finger joints, thumb, carpal bones, and the growth plates of the wrist, then reports an overall bone age in years and months. BONE AGE ASSESSMENT • Select a hand X-ray image and get a result in seconds • Overall skeletal age in years and months • 17 anatomical regions detected and marked on the image, each with its own regional age estimate — see at a glance whether maturation is even • Automatic image validation: photos and non-radiograph images are politely declined GROWTH & ADULT HEIGHT — FREE • Enter age, height, weight, and the parents' heights • Adult height prediction from the child's current growth percentile, plus the classic mid-parental (Tanner) genetic target range • CDC growth-chart percentiles for height, weight, and BMI, with beautiful interactive charts showing exactly where your child sits PRIVATE BY DESIGN • All analysis runs on your device — X-ray images never leave your phone • No account, no tracking, no data collection LANGUAGES English, 简体中文, Español FREE AND PRO The free version validates your image and shows the detected regions; the growth calculator is fully free. Unlock complete results — the overall bone age and all 17 regional ages — with a single-use Credit or the Bone Age Pro subscription (auto-renews until cancelled in your store account settings). IMPORTANT BoneAge is for informational and educational purposes only. It is not a medical device, has not been evaluated by any regulatory authority, and must not be used for clinical diagnosis or treatment decisions. Bone age estimates carry a typical error of several months. Always consult a qualified clinician about your child's growth and development.
