About this app

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
