A simple app that uses the Google Cardboard API to simulate anaglyph 3D glasses. This app uses the more common red-cyan configuration where a red color filter is applied to the left eye and a cyan color filter is applied to the right.
A Google Cardboard VR headset or equivalent is required to use this app.
