打完一场球，你知道自己是哪一拍出了问题吗？ 动作帧用手机（可搭配 Apple Watch）记录你的挥拍，在本机跑骨架识别，把每一拍拆成看得懂的数字和画面——不再靠感觉练球。 【逐拍动作分析】 录一段挥拍视频，App 自动找出每一次挥拍，给出肘部角度、击球点高度、挥拍节奏等指标。支持慢放、逐帧对照、3D 骨架回放，看清自己动作到底哪里变形。 【AI 教练点评】 基于这一场的真实数据生成点评：具体到第几拍、肘角多少度、击球点有没有过肩，并从训练方法库里挑出针对你的练习。 【训练方法 100 套 · 常见错误 110 种】 每条都有图解和标准做法，离线可看，不联网也能练。 【知识讲堂 30 讲】 从握拍、步法到单打双打战术，把打球的道理讲清楚。 【训练计划与课程】 按你的水平生成周计划，完成课节记录进度，趋势图看得见自己的变化。 【球友圈】 约球、求指点、晒战报，找到附近一起打球的人。 【球馆查找】 定位附近的羽毛球场馆，看距离和联系方式。 【Apple Watch】 戴表训练可实时看心率与挥拍数，与手机视频自动对齐。 —— 关于隐私 —— 视频与骨架分析全部在你的手机上完成，视频不会上传服务器。只有你主动发布到球友圈的内容才会上传。 —— 关于 AI —— AI 点评、评级、训练计划由大模型生成，内容仅供参考，不能替代专业教练的当面指导。挥拍检测在多人同框（例如双打）场景下仍在测试中，此时数据可能不稳定，App 内会明确提示。 —— 关于健康 —— 本 App 提供的是运动训练参考，不构成任何医疗建议。运动前请做好热身，如有不适请及时就医。 有任何问题欢迎在 App 内反馈，我们会持续改进。
