Trackpal

iPhone Mac

Your thumb already
knows how to
do this.

Trackpal turns the phone in your pocket into a trackpad for your Mac. Put it flat on the desk and move the cursor.

Every touch sample the screen produces, de-batched rather than averaged.

Motion goes over UDP, on its own receive queue, paced to the display clock.

Measured over USB
1.3ms

Finger to cursor, with no interpolation smoothing the gap. Wi-Fi adds the radio's own latency.

Everything a trackpad does

The gestures are the ones your hands already run without thinking. Nothing here needs learning.

Move
One finger anywhere on the glass moves the cursor.
Tap
Tap to click. Tap a corner to right-click — you pick which corner, and how big it is.
Scroll
Two fingers scroll, and keep coasting after you let go. Natural direction is a setting.
Select text
Double-tap and drag, the same way you would on a real trackpad.

Two halves, one pairing code

The Mac app runs in the menu bar and shows a code. Type that code into the phone once, and the two find each other on their own after that.

Start with the Mac half.
