Your Windows workspace, extended.

SpanScreen turns the iPad beside you into a real, interactive Windows display—without sending your screen through the cloud.

A simpler second screen

From launch to extended desktop in three steps.

  1. 01

    Launch on Windows

    SpanScreen creates and configures a dedicated virtual display.

  2. 02

    Pair your iPad

    Scan the short-lived QR code or open the private join link.

  3. 03

    Move your workspace

    Drag a window across and interact using mouse, keyboard, or touch.

Privacy by architecture

Your pixels take the short route.

Azure coordinates short-lived pairing and connection details. Screen frames and input travel directly between your Windows PC and iPad over encrypted WebRTC.

  • No cloud video relay
  • No account or screen-content storage
  • One-time viewer tickets

Built in the open

SpanScreen is actively taking shape.

The current release is a development preview focused on a sharp, low-latency iPad experience and a secure local media path.
