All Thinglink 360 images and video can easily be viewed with a mobile VR headset. Open the asset you wish to view in your mobile browser. In the upper right corner you'll see a headset icon. Tap that. Next you'll see a graphic that indicates you should rotate your screen to landscape orientation.
In landscape the image will appear in VR and can be viewed with a headset. Use the pointer in the field of vision to open tags.
