My best friend and I built an iPhone app that tracks a batted ball at 240 FPS and calculates exit velo + launch angle from just the camera

This is Ballista. You put an iPhone beside the hitter, hit normally off a tee, and the phone tracks the baseball immediately after contact to estimate: Exit velocity Launch angle Projected distance No radar gun. No Rapsodo. No external sensors. Just the camera. It is meant to be an alternative to multi-thousand dollar hardware hitting systems. We’ve been beating the hell out of this thing for the past few months and recently opened the new version to external tes

痛点：传统击球数据采集硬件（Rapsodo/HitTrax 等雷达与传感器系统）动辄数千美元，业余球员、青训教练和家长买不起，只能用手机摄像头做廉价替代方案。

目标用户：棒球/垒球打击教练、青训机构、大学与高中球队、业余球员及愿意为孩子付费的家长。

证据：It is meant to be an alternative to multi-thousand dollar hardware hitting systems. / All we really want right now is more real swings through the system.

变现：订阅制（月费 9.9–29.9 美元，免费试用后解锁导出与历史数据）+ 教练/球队多席位团队版 + 与训练机构合作的 B 端授权；也可考虑按次付费的击球分析点数包。

MVP：两周版：仅用 iPhone 240fps 慢动作 + Vision/Core ML 检测击球后首帧球体位置与轨迹两帧，拟合出球速、发射角与估算距离；只做单次击球结果卡片 + 本地历史记录，绕开多球追踪与云端分析。

竞品：Rapsodo、HitTrax、Blast Motion、Pocket Radar、Diamond Kinetics

摘要：Reddit 用户与好友用 iPhone 240fps 摄像头做出击球追踪 App Ballista，无需雷达枪即可估算出球初速、发射角和预测距离，定位是数千美元硬件击球系统的廉价替代品，目前开放 TestFlight 免费测试。帖子本身无明确付费原话或收入数据，但对应的是已有真实付费市场（Rapsodo/HitTrax）且价格差距巨大，属于有验证但需自证付费转化的小众垂直机会。
