About

ScoreShelf

Features
Read full description

ScoreShelf is a simple sheet music viewer designed to help you manage PDF scores comfortably on iPad. Import PDFs into your library, organize them as scores, and quickly resume practice from the last page you opened. With Apple Pencil support, you can write notes and marks directly on your scores, just like on paper. Bookmarks let you remember pages you often return to or important places in a score. You can also save current practice locations as “Practice Spots,” so you can return to the parts you want to work on next without searching. Practice History helps you look back on your practice in a quiet, visual way. You can view a calendar-style heatmap of your practice, see which scores you worked on in the past, and return directly to the score and page you were practicing. ScoreShelf is not an app that pushes you to practice or judges your progress. It is a quiet shelf for your daily practice, remembering the scores you need, your handwritten notes, your practice history, and the places you are working on.
