pyFileDiff

This app compares 2 text files and displays the differences in a HTML view. The view can be zoomed-in and zoomed-out as needed.

The text files can be chosen in the app using a file chooser or they can be loaded from the clipboard.

They can also be passed on app startup. On Android, this requires persisted folder permissions. You can manage these permissions under the "Manage folder access" menu item.
