Hello! I'm an orchestral musician, and I'm looking for an app that will help me keep track of my sheet music library. I have lots of music, and want an app that will act as a 'master index', so that ill know which pieces by, for example, Beethoven are in my library, and which I need to get from the orchestra library. I have a paper list, but its getting more and more complex, and its difficult to keep things alphabetical as the library grows. When I search the app store for something to organize lists I inevitably get many 'to-do'list options. Ive tried other ways of scearching, but haven't come across anything that even comes close to fulfilling my needs. I can't be the only person looking to keep long lists of info organized! As what I'm looking for is so basic, I really don't want to spend much more that $1. Help!!
