Full description
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 ADULT HEIGHT PREDICTION • Enter the child's current height to project adult height and remaining growth from the assessed bone age • Six growth standards to choose from: CDC (US), WHO, China, UK, Japan, South Korea • Save measurements per child and track their growth trajectory 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.
