APP NAME: Notes
WHAT IT DOES: Included on every iPhone, this familiar app displays a yellow ruled pad for note-taking. Notes can be saved or emailed.
LEMON FACTOR: For such a basic, utilitarian app, this one inspires some passionate haters—and not just for its relative lack of integration and syncing features. Marco Arment, the creator of the widely admired Instapaper app, blames Notes' ugly font, a casual typeface called Marker Felt. "There's absolutely no excuse for using the Marker Felt font, an ugly, unreadable font in an application whose sole purpose is reading and writing text," he says.
