Your wall is the net

Dink watches every ball you hit against a wall, plays it on through to a ghost opponent on a virtual court, keeps the score and coaches you in your ear.

The shot keeps going

When your ball reaches the wall, Dink knows where it is and how fast it is moving. The same physics carries it on through the wall, so a wall becomes a full 44 ft court.

  1. 1

    Set up once

    Tripod on the kitchen line, a few metres to your right. Tap the wall line and the kitchen line, and the court is calibrated.

  2. 2

    Play the ghost

    Hit against the wall. Every shot flies on through it onto a virtual court, where a levelled ghost plays it back. Games to 11, real rules.

  3. 3

    Hear the coach

    Calls and one cue per rally in your AirPods, between shots, never mid-swing. Then replay every rally in 3D.

Two minutes to set up

Any wall with a flat floor in front of it. Put the phone where it can see your feet, the ball and the wall line all at once.

  • Tripod 4–5 m to the right of your hitting laneFar enough to keep your whole body in frame
  • Lens on the kitchen-line extension, 1.0–1.2 m highKitchen calls need to see that line edge on
  • Turned 15–20° toward the wallSo the ball is tracked all the way to the wall
  • Rear camera, HDR off, AirPods inCalls arrive in your ears, not from the phone

A partner who never gets tired

A ghost that adapts

Levels 2.0 to 4.5 with five personalities, from the dinker to the banger. It rates up as you win.

Line calls you can trust

In, out and short from a flight model with drag. Close calls go your way, like a fair partner would.

USA Pickleball rules

Serve, two-bounce, kitchen volleys and momentum faults, scored the way you play on court.

A coach, not a commentator

One focus at a time. Cues fade as you improve, so you learn the feel, not the voice.

Your body, tracked

Feet, knees, paddle height and contact point, on the phone at camera rate.

Replay in 3D

Scrub any rally: your arcs, the ghost, and the virtual court behind the wall.
