RallyAI: Tennis

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
