Cardboard

Cardboard at a glance

Cardboard turns a compatible Android phone into a simple virtual reality viewer. It is aimed at people exploring 360-degree content with a Cardboard-style headset, as well as developers testing mobile VR experiences. The app can help pair a viewer by scanning its QR code, so the display is adjusted for the headset’s optics.

What it does

• Calibrates supported viewers using QR codes.
• Provides access to compatible VR experiences and demonstrations.
• Uses the Cardboard SDK as a reference point for mobile VR development.
• Relies on the phone’s screen and motion sensors to create a stereoscopic viewing experience.

Who it suits

This is a practical starting point for users who already have a compatible viewer and want to try phone-based VR without dedicated hardware. It also fits developers and students looking for a straightforward sample app connected to Google’s Cardboard ecosystem. The experience depends on the viewer, phone sensors and the quality of the available VR content, so results can vary between devices.

Cardboard has a broad install base, but its rating suggests a mixed experience across users and hardware. It is most relevant as a viewer setup tool and demonstration app rather than a full VR content library. If you are testing mobile virtual reality or checking whether a Cardboard-style headset works with your phone, its purpose is clear.
