I 100% agree, Termux shows, what a useful tool a smartphone can be. Do I need an app to look at the EXIF of a photo? No, I just use Phil Harvey's excellent exiftool[1] in the shell. Resize or rotate an image? Or even a number of images? Imagemagick does the job. The power of the command line in your hand ;-)
