The app loads free news, record reviews, tour dates and band portraits with videos and streaming playlists. The results can be filtered by rock & metal genres and adjusted to suit those who know the scene as well as fans who want to get to know their very first bands better. The extensive archive contains hundreds of thousands of texts from 40 years of rock hard. For complete use and the current e-paper with various reading modes, a subscription must be taken out with the publisher. According to Der Spiegel, rock hard is “the central organ of heavy metal fans".

The claim "critical - competent - independent" was not chosen by accident.
