VRTest is an Android app that helps you determine your phone's compatibility with virtual reality. Developed by Dernogard, the app is free to download and falls under the Utilities & Tools category.

The app checks your phone's settings and evaluates whether it is suitable for VR or not. If your phone is suitable for VR, the app will tell you so and you can start using it with confidence. If your phone is suitable for VR with restrictions, the app will inform you of the limitations and what you need to do to overcome them. For example, if your phone does not have a magnetometer, you will need to buy a joystick to control games with active actions like shooting or jumping.

Overall, VRTest is a useful app for anyone who wants to know if their phone is compatible with virtual reality. It's an easy way to avoid buying a virtual reality helmet that won't work with your phone.
