Watch the points.
Skip the walking.

How it works

  1. Load your match video

    Tap Load a match video and pick the recording from your phone or computer. It plays right in the browser — nothing is uploaded.

  2. Name the players

    Tap Players in the top right and enter both names. They show up on every button and the score.

    Two name fields, filled with Alex and Sam
  3. Choose the counting

    Under Initial pick a Tie-break or a full Set, and who served first. Video starts in the middle of the match? Enter the score at that moment and the rotation lines up.

    The Initial panel: tie-break or set, starting score, first server and side
  4. Start a rally on the serve

    Scrub to just before the serve and tap Start rally. The button tells you who is serving and from which side — if that is wrong, ⇄ switches the server and ← L / R → the side.

  5. Pick how the point ended

    When the ball is dead, tap the outcome: a winner or a fault by either player, or an Ace. First serve out? Tap ↻ 2nd serve — tapping it again makes it a double fault.

  6. The score keeps itself

    The scoreboard counts with you and rewinds when you scrub back. Open Statistics for aces, double faults, winners, errors and serve percentages per player.

  7. Review and correct

    Every point lands in the Rallies list. ▶ jumps to it, tap the 🎾 to fix who served or the side tag to fix the side, and × removes a point.

  8. Watch rallies only

    Hit ▶ Play rallies only and Baseline jumps from point to point — no ball fetching, no towel breaks.

  9. Export or come back later

    Your tagging is saved in the browser as you go — load the same video again and it all lines up. Export Rallies saves it as a file, Import picks it up on another device.
