Automatic line calling
In or out, and by how much
Five cameras sit up and out of play, set to the lines of your court. Every bounce is seen from more than one camera and measured against the line. The call comes up on the court screen for the game you're playing.
-
Instant replay
See the bounce again
The replay plays in real time on the screen at the net. Everyone on court sees the same bounce. No phone in your hand, no walking over to look at the line.
-
Close calls
The call comes with the proof
A ball lands near the line and each side sees it differently. Look up: the Judge shows the bounce from three cameras, the ball on the line from above, and the verdict, in or out and by how much. Then serve the next point.

After the game
Every rally as a clip
Clips of every rally, ready when you walk off. Speed in mph and spin type and intensity on every shot. Top serve, top return, longest rally, and how each rally ended.

Questions
Before you play.
Paying
Who pays?
Each player pays for their own game. Your card is only charged once the game starts. If it never starts, nothing is charged. Courtside Judge Unlimited is one plan for a month on every RackIT court. Games a venue starts for you, like tournaments and hosted events, are included by the venue.
No install
Do I need to download anything?
No. RackIT Judge works in the browser on any phone or computer, at judge.rackit.net.
Friends
Playing with friends?
Everyone playing joins with the same code. Your friends tap Join Another Game in the app and type the code from the court screen. One to four players pick a starting position, then the host taps Start Game.
Privacy
Is my game on video?
While a game runs, five fixed cameras record silent video of the court area. No sound is recorded. Video is also copied, apart from your account, to develop and train RackIT's models. RackIT Judge does not use face recognition.
