I am a mental health specialist, working with various phobias and "insectophobia". I found PsyTechVR in the recommendations this weekend on SideQuest. Having entered the app with my login and password, I immediately stumbled upon the fear of flies, cockroaches, and spiders. 3D graphics look very realistic - hundreds of cockroaches, spiders, and other insects were crawling on the walls, floor, etc...The noise from the flies was so disgusting... From the point of specialist view, I consider that the app has immersion, and the virtual exposure looks realistic; that's why facing those fears would be helpful. I am most impressed by the system of delivering information - learn, train, and repeat. Try it out
