QuadViewer is a photo viewer application that allows you to view and compare photos by dividing the screen into two, three, or four panels.
Since you can select photos not only from the photo library but also from the Files app, image files from various cloud services and external devices can be loaded as well (connection settings are required in advance).
In addition, the inspector function makes it easy to compare EXIF data.
