Fly is essentially Google Earth VR running standalone on Meta Quest headsets and Apple Vision Pro.
On Quest Fly joins Earth Questanother app with the same pitch. On Apple Vision Pro, it's the first time you've Google Earth VR experience on the device.
Both apps use Google's new Photorealistic 3D Tiles API for 3D terrain and buildings, with lower peak quality compared to the official Google Earth VR. The biggest difference, however, is that Fly and EarthQuest run on the headsets themselves, without the need for a PC.
Like the official Google Earth VR and EarthQuest, you can travel anywhere in the world and find 3D geometry in most cities and landmarks.
By default, Fly places you in a giant drone with a strange locomotion system that has you leaning or moving your body relative to the center of your playspace to move horizontally. This can be changed to the left thumbstick in the settings for more traditional controls, and you can also turn off the drone model for an unobstructed view of the landscape.
What you won't find in Fly, however, is Google Street View, the ability to launch into immersive 360-degree imagery captured from positions along most streets on the planet. This is a key feature of the official Google Earth VR and is also available in EarthQuest.
Fly is available for $10 on the Meta Quest Store or $15 on the visionOS app store. Alternatively, EarthQuest is available for $9 on the Meta Quest Store.
