Along with the release of iOS 10.3 earlier today, Apple has also updated its iWork suite of productivity apps with several new features, including the ability to open password-protected documents in each app using Touch ID and format text as superscript of subscript and change text background color. Pages 3.1 also allows users to bookmark document sections, use LaTeX and MathML notation, and import and export RTF documents. Numbers 3.1 improves the editing experience for entering data and formulas, adds an action menu for quick access to common tasks, and allows users to add current or historical stock information in spreadsheets. In Keynote 3.1 slide masters and backgrounds can now be changed up, and a new presentation rehearsal view shows current slide, presenter notes, and timer on a single screen.
