This app is for astrophotography with your smartphone. You can take pictures with long exposure times like classical astrophotography with a DSLR or CCD/CMOS camera.
DeepSkyCamera takes pictures of the stars including a plan. You take the pictures in RAW format. Android uses the format DNG which can be processed with the well-known stacking software.
