it does not display info of the selected image, instead picks image at random.

Very clear information about physical and file size

This new app fails to provide useful EXIF information for any photographer. Extremely limited, not even identifying the lens used. Worse, jpeg images opened into Firefox on the user's own computer reveal zero information, just a spinning image. "Some" images, such as photos on a site like fredmiranda.com, which are on an html website do reveal the, again, severly constricted EXIF data. This app is not useable on 6/14/2019 for this photographer's purposes. Zero stars is not an available rating. Only the effort as a start can be commended. Full or nearly full EXIF is needed, or forget it.
