Yulio Viewer is a free Android application developed by Yulio Technologies Inc. that allows architects and designers to create and share fully immersive virtual reality experiences from their CAD tools. The app provides access to these experiences for anyone with an Android smartphone and a Google Cardboard-style headset.

To start exploring, users need to click on a Virtual Reality Experience (VRE) link provided by their designer or from the yulio.com gallery, connect their headset with their email address, and Yulio will deliver the experience directly to their device.

It is important to note that this experience requires a Google Cardboard viewer and Android 4.4+. The minimum recommended devices are Samsung Galaxy S5/6, Samsung Galaxy Note 4/5, Nexus 5/6, and the performance may vary on other devices.

Overall, Yulio Viewer offers a unique and immersive way for architects and designers to showcase their designs and for users to experience them in virtual reality.
