  1. Flip

    Screen down, top edge away from you. The camera on the back now sees the ceiling — that's what Topo tracks.

  2. Slide

    Move the phone like a mouse. Topo follows it 60 times a second, down to a fraction of a millimetre.

  3. Tap

    Tap the back to click. Tilt a little to scroll. Lift it and the pointer stays where it is.

No dongle. No pairing. Nothing to charge.

Requirements

  • iPhone on iOS 27
  • Mac or MacBook on macOS 27
  • Same Wi-Fi
  • Something to slide on — a mousepad or a sheet of paper. Bare glass sticks.
