This is the first app to automatically show you your sheet music in your preferred clef. Don't be intimidated anymore by hard lines when playing in a new clef - like I was, before finally picking up the piano. The computer vision algorithm will handle PDFs, screenshots or even camera photos. Parts can be single stave or multiple. Just choose music with symbols like the ones shown, not jazzy font. Read the help menu for tips on getting the best quality, or ask support. I am trying to create the best visualizer for musicians here, and for free.
