RackIT Judge

Never dispute a line call again. RackIT Judge puts your own Courtside Judge on the court. Five cameras watch every bounce, call the lines, and play the instant replay on the screen at the net while you play. Walk off the court and every rally is already in the app, with the speed, spin and swing of every shot. RackIT Judge works at venues with RackIT courts, and you can find one near you in the app.

The call comes up the moment the ball lands. In or out shows right on the court screen for the game you're playing, and every bounce is seen from more than one camera. Short serves and balls that don't make it over the net are called too. There's no arguing and no walking over to look at the line. Look up, see the call, and serve the next one.

Then the bounce plays again on the court screen in real time, so everyone on court sees the same replay. Nobody needs a phone in their hand. The screen calls the lines and the game keeps moving.

Follow your game live in the app with the rally count, top serve, top return and how the latest rally ended. Check the call on any rally with every call listed in order, then tap one and the video jumps to the camera with the best view, zoomed in on the bounce.

You only watch the action. Every rally is its own clip, with no dead time between rallies and no scrubbing through a full recording. Switch camera angles, slow a rally down to half or quarter speed, step through it frame by frame, jump from shot to shot, pinch to zoom, and save a favorite rally to your phone.

Every shot shows its speed in mph and its spin, whether topspin, backspin or sidespin, from light to heavy. You also see the swing behind it: forehand, backhand, two-handed backhand, overhead or volley. The game in numbers shows your top serve, top return, longest rally, and how each rally ended.

Starting a game is simple. Pick a RackIT venue and a free court, then tap Start a game and an 8-digit code appears on that court's screen. Everyone playing enters the same code and picks a starting position, with one to four players in a game. The host taps Start Game, and the Judge takes it from there.

No password to make or remember. Sign in with Google or a code we email you. One account works at every RackIT court. RackIT Judge saves a rally video to your device only when you tap Save Video.

Courtside Judge runs line calling and instant replay on the court you're playing on, for that game. You pay for it at the court as your game starts, and there's nothing to buy after you play. 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. New players can start a free Courtside Judge trial at a court. No card.

Find a RackIT court, enter the code, and play. The Judge has the lines.
