For Mac and Android

Your Android device is a second screen now.

SideDroid turns an Android device into an extra display for your Mac. Plug it in and the screen extends. Unplug it and SideDroid carries on over Wi‑Fi.

How it works

Three steps, and you only do the first.

A menu bar app on the Mac watches for your device. It adds a virtual display, streams it with the Mac's hardware encoder, and sends your touches back as clicks.

Step 1

Plug it in

Connect the device over USB with USB debugging allowed. That's the only setup.

Step 2

The screen extends

A new display appears in macOS. Drag windows onto it like any monitor.

Step 3

Unplug, keep going

SideDroid learned the device's Wi‑Fi address while it was plugged in, so it reconnects over the network.

Menu bar

Lives in the menu bar. Pulses while it works.

The status line shows a pulsing device while your screen is being extended, and a still icon the rest of the time. Pick a device to connect to it straight away, or choose USB or Wi‑Fi.

Give the device in your drawer a job.

An old Android device makes a good second screen for notes, chat or a music player. SideDroid sets it up the moment you plug it in.
