I noticed my reply went to a post in submission completed but should be here in a new one, because although the name is similar and author and license are the same, it is being treated as different app than the Aard already here.
Copying the text:
A more advanced aard has been released by same author
Name is Aard 2 and isn’t just a new release of Aard but a much better interface and a different, better dictionary format.
https://github.com/itkach/aard2-android (with building instructions)
Can you please please have a look and try to add it?
Usability same or better and no antifeatures noticed
