Putting in the practice but not sure what to change? Rally helps adult tennis players understand their swing and choose what to work on next.
Record or import a swing, review your movement and feedback, then take a focused practice cue or drill to your next session.
KNOW WHAT TO WORK ON
Rally checks whether your clip is clear enough to analyze. Suitable clips receive a score, confidence level, and a priority to practice. Review available movement evidence and related drills. Swing analysis supports forehands, two-handed backhands, and serves.
SEE YOUR SWING CLEARLY
Review your recorded swing with a full-motion skeleton overlay when motion evidence is available. See that evidence alongside your feedback and return to saved reports in your history.
SKELETON OVERLAY
Choose a 2–60 second tennis video, select yourself, and review a moving skeleton of your visible body joints. Processing runs on your iPhone. Watch, save, or share your overlay, with optional original audio for this local mode. Detection can be imperfect; uncertain or hidden joints may be absent. Ball tracking and statistics for this mode are still under construction.
PRACTICE WITH A PURPOSE
Follow a practice cue or drill for your coaching focus. The practice library also includes forehand, backhand, serve, and footwork drills with video and clear steps to follow on court.
BUILD YOUR TENNIS BASICS
Newer to tennis? Follow short lessons for your forehand, two-handed backhand, and serve. Start with the grip, practice close to the net, then move back. Learn simple rules for serving and playing points.
START WITH YOUR OWN SWING
Record a swing or choose a video from your iPhone. Rally removes audio before uploading a clip for analysis. No Rally account login is required. Analysis requires internet access. Saved swing history is stored on your iPhone. Rally is for adults age 18 or older.
