MANY of us use our phones to jot down notes, whether we’re in a class, at an interview or trying to remember a shopping list. And many apps are available to help.

One fabulous option for both students and professionals is Noteshelf. The app functions as a library of notebooks, letting you create a new book for each class or business meeting. You can title the notebooks and customize their covers to help identify them later. You can choose from different types of paper, including squared, lined, plain, and specialized designs intended for sports scores or music notation.

When making notes in a book, you can type into text blocks, create freehand text, make diagrams and insert photos and audio. These elements can be combined on one page, and when one page is full you simply move to the next.
