Edit:
Meanwhile I have another table where I get the installation finally out now muste allerdins festellen the people here at Amazon a hopelessly outdated app is sold.
Currently is in fact at the time the 2.0.4 from 05.10.2015 and here there is only the ancient version 1.9.4 from 31.05.2013
This obsolete version is now probably no longer have access to current Krten Downloads.
So the rating is not for the app because the really least. 10 star is worth evaluating is aimed at Amazon tighten the money here for the people ancient Apps!
So if you really want to have the latest updates for this app then buy in no case at Amazon but look at alternative app marketplaces !!!
