See what your stroke is actually doing.
Record a short clip of your serve, forehand, or backhand. TennisLens breaks it down frame by frame, scores your technique, flags the errors costing you points, and gives you the drills to fix them.
Record side-on, full body in frame, a 5–15 second clip of a single stroke.
Frame-by-frame analysis
A score, and the why behind it.
Every stroke is graded across its phases — preparation, swing path, contact, follow-through — with a clear overall score, your skill tier, and the specific errors holding you back.
Progress over time
Watch your strokes improve.
Every clip is logged so you can see your scores trend up per shot, track each part of your technique, and keep a daily streak going as you climb the ranks.

Private by design
No account needed. Clips are analysed and never stored, and your history stays on your device.
Privacy
Your clips aren't kept.
TennisLens works without an account. When you analyse a clip it's sent for AI processing and discarded right after — we don't store your videos. Your analysis history and scores live only on your own device.
FAQ
Good to know.
Do I need an account?
No. TennisLens is fully anonymous — no sign-up, email, or password.
Are my videos stored?
No. Clips are analysed and discarded immediately afterwards — never saved on our servers.
Is this a substitute for a coach?
It's a sharp second set of eyes, not a replacement. The feedback is educational, not professional coaching or medical advice.
What makes a good clip?
Side-on angle, full body in frame, 5–15 seconds of a single stroke. Slow-motion works especially well.
