Camera.
The app uses optical zoom but the result depends on the resolution of your sensor and the processor's frame rate.
Change the focus magnification brightness contrast etc. of the camera and capture photographs and record videos of objects that are far from you with the aid of philtres and zoom that would rely on your mobile. Manually monitor the camera such as focus which will assist with this application in dark areas.

Special Notes: Please remember that all the algorithms used in this app are not a true telescope camera with the maximum potential radius of the phone camera.
