The hologram court does not line up with mine

Stand on the centre mark behind your baseline, face the net, look straight ahead and tap Set Court. Then use the arrows on the panel to nudge the white lines until they sit on your real lines, and turn the lines off. If it drifts, tap Set Court Again from the same spot.

My phone will not connect

Open Holoport Tennis on the iPhone and keep it open with the screen on. When it asks, allow Bluetooth and Local Network access on the phone, and Local Network access on the headset. If you said no earlier, turn them back on in the Settings app. The phone and the headset should be on the same Wi-Fi network; Bluetooth works without one. The phone shows Connected when it has found your Vision Pro.

The racket points the wrong way in my hand

Hold the phone like a handle: top end out of the thumb side of your fist, screen against your palm. Then point the top of the phone at the net and press and hold the button on the phone screen for a second to calibrate.

I keep missing the ball

Turn on Assisted hitting for a bigger hit zone while you learn the timing, slow the machine down, or give yourself more time between balls. Full swings track best with the iPhone handle.

I play left handed

Set Racket hand to Left on the panel.

The balls bounce too high or too low

Change the speed and the topspin. More topspin makes the ball dip and kick up after the bounce. Clay and grass bounce differently from hard court, so pick the surface you are playing on.

Is it safe?

Play on an open court with nobody near you, use a wrist strap if you hold your iPhone, and stay aware of the net and the fences. Take the headset off if you feel unwell.

What does the app collect?

Nothing. It has no account and no server, and the phone talks only to your own headset. The details are in the privacy policy.
