## What is BoneAge?

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.

### 5/5 — 总算找个靠谱的工具

*2026-10-13*

朋友推荐的这个，说是测骨龄很方便。试了一下发现确实不错，不仅有具体的年龄数值，还会分析发育潜能。这对于我们调整孩子的饮食结构很有帮助，比如发现发育超前了就要少吃点高热量的。总之是个带娃必备的实用助手，帮了大忙了。

### 5/5 — 比我想象中要快很多出结果基本不用怎么等待

*2026-10-12*

周末带孩子去体检拍了片子，回来就迫不及待想知道具体情况。上传片子后识别速度超快，算法感觉很先进。里面还有一些关于长高的小建议，比如睡眠和运动方面的，挺贴心的。主要是省去了在医院咨询医生排队的时间，效率提高了一大截。

### 5/5 — 对于咱们这种非医学专业的人来说门槛很低

*2026-10-11*

本来以为这种医疗类的东西会很难用，结果发现只要跟着提示传照片就行。生成的报告里会有详细的百分位数值，能对比同龄孩子的平均水平。以前看医生的手写报告像看天书，现在通过这个软件终于弄明白什么叫骨龄落后了，非常有参考价值。

### 5/5 — 预测身高的功能很实用

用了几次感觉数据挺稳的，而且里面的对比图很细致，能看出来哪些骨头还没完全钙化，确实能学到不少生长发育的知识，五星好评吧。
