Dynaper was designed to be very easy to use. It does not require any knowledge about how to create dynamic wallpaper.
To create a dynamic wallpaper user only needs to provide images and click autosuggest time button. Time of each dynamic wallpaper can be adjusted manually within the app.
Dynaper also serves profesional users that prefer to use keyboard over mouser. Dynaper made sure that core macOS technologies like undo/redo, next key view loop work out of the box.

When you add a new file to Dynaper, it automatically tries to read all timestamps provided. The highest priority is the timestap included in the filename. The other timestamp dynaper looks at is date of creation in EXIF metadata.
