Black Hole Camera

Uses the camera of your phone to simulate the Black hole being 1m (3.28ft) away from you. Black hole mass here is similar to the mass of the planets like Mars or Earth. You can change the mass with the pinch gesture or slider. Allows you also to save the full-resolution photo of the Black Hole. Uses the real field of view angles from your phone's camera.

Requires only access for the camera and the SD card (to save high-resolution photos), nothing more. You can revoke the SD card access - it will be still usable, although with limited functionality. Number of ads = 0.

It is still on progress, I yet have to test on different-vendor phones and improve the 15 different translations - right now nearly all of them are generated by on-line auto translators which is far from perfect.
