## What is RallyAI?

RallyAI is your all-in-one tennis training companion — daily logging, Apple Watch recording, and AI video analysis in a single app.
Whether you're drilling or playing points, RallyAI records every swing, visualizes your progress, and uses on-device AI to pinpoint what to fix — right on your iPhone. It's like having a tennis coach in your pocket, turning smart practice into a habit.
【Log & Track Every Session】
• Tennis Journal: a calendar view of every practice and match, so your consistency is obvious at a glance
• Data Board: automatically totals your shots, top/average ball speed, distance covered, intensity, and calories
• Session Highlights: distills each session into standout moments and a stat card you can revisit anytime
• One-Tap Share: generate a polished stat poster and highlight clips for social media
【Apple Watch Live Recording】
• Your wrist is the sensor: wear Apple Watch to capture swing count, heart rate, movement, and active time
• Auto-merge with video: Watch workout data syncs and aligns to the video shot on your phone
• Automatic shot detection: motion-based swing detection — no manual tagging
• Start in a tap: begin/end a session right from your wrist, no phone needed
【AI Video Analysis】
• Smart swing detection: automatically identifies forehand, backhand, serve, and volley, tagging each on the timeline
• AI Coach chat: talks through your session data and gives targeted, personalized tips
• Slow-motion replay: per-shot clips with frame-level playback and comparison
【How to Use】
1. Start a session on Apple Watch, or record directly with your phone / pick a tennis video from your library (shoot landscape, full court in frame for best results)
2. The app runs pose detection, court detection, and ball tracking, and merges your Watch workout data
3. Review each shot's speed, placement, score, and long-term trends in the Journal and Data Board
4. Chat with the AI Coach for training advice
5. Export highlights or slow-motion replays, generate a stat poster, and share to social

### 5/5 — 打球记录很方便

*2026-08-16*

用了几次，自动记录和剪辑高光挺省时间，不用再从整段视频里慢慢找。新版实时模式和语音反馈也很有意思，偶尔识别还有一点偏差，但整体体验不错，期待后续继续优化

### 3/5 — 闪退

*2026-06-12*

一直闪退，解决一下好吗…

**Developer response:** 感谢反馈，新版本已修复
