In Solar System VR you can basically fly trough our solar system. This app was made for the Durovis Dive/Google Cardboard and can or should only be played with it.
Basically there is one control -> Look around!
You're moving in a moderate speed to the direction you're looking.
If the camera drifts, lay down your phone on a table and wait like 20secs until it stops moving, now it should be calibrated.
For a better gameplay, the planet scales are not 100% real.
Compatible Wirth every HMD like Durovis Diver, Google Cardboard, Homido and man more!
