Backstage gives live-music fans a place to remember the shows they attend. Log a concert, rate each artist on the bill, record openers, venue details, and notes, then browse artist pages or see which upcoming shows friends plan to attend. Profiles, follows, likes, replies, and sharing make it a social diary as well as a private concert log. The app is free to download, and no in-app purchase was surfaced in the current listing. It is rated for ages 13 and older and includes messaging, social networking, and user-generated content. Apple's privacy label says contact information and user content can be linked to an account, so it may not suit people seeking a fully private journal. Backstage is a very new service with an early 1.1 release; community size and coverage can change as more fans join.
