How it works
-
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.
-
Name the players
Tap Players in the top right and enter both names. They show up on every button and the score.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Watch rallies only
Hit ▶ Play rallies only and Baseline jumps from point to point — no ball fetching, no towel breaks.
-
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.
