Technique analysis: phone video and swing phases
A player uploads a video of their game from the phone and gets a review: shots, court movement, technique errors and a 0–100 score for each stroke phase. Works without a smart court too. The video is deleted after processing — numbers, short shot clips and tips remain.

What it is and why
Not every club has a smart court, but everyone wants to improve. Technique analysis works from an ordinary phone video: the player films their game with the court in frame and uploads it in the app.
The server finds the court and players, counts shots and movement and checks strokes against technique rules set by the club coach. The coach sees students' reviews in the admin panel.

In detail
Technique analysis
Technique analysis from a phone video
The player uploads a video of a game from a phone. The server finds the court and the players — the player can adjust the court corners — counts shots and movement across court zones and checks strokes against technique rules that the club coach sets up in the admin. The video is deleted right after processing; the figures, short shot clips and training tips remain.
Swing phases /100
Each swing phase — preparation, backswing, contact, follow-through — gets a score from 0 to 100: the share of shots in which the rules of that phase found no errors. Backswing and contact are scored on volleys and overheads. With fewer than two measured shots there is no score. The score is shown in the app and in the coach's admin.
Limits, honestly
Limits, honestly
- Quality depends on filming: the court must be in frame and the player not too far away.
- Backswing and contact are scored on volleys and overheads; with fewer than two measured shots there is no score.
- This is an estimate from phone video, not from smart-court 3D poses.
- The video is deleted right after processing — it cannot be rewatched in the app.
