The folks at Evernote rolled out a pretty significant update to its iOS app today that includes rich text support, shared notebooks, a redesigned iPad interface and more.
Andrew Sinkov said on Evernote's blog that implementing rich text was "a doozy." Users can stylize text, add highlights and URLs, create headers and make lists. This also involved overhauling a bit of the iPhone app to work in the features. In addition to creating new rich-text messages, existing ones can be edited. However, you still can't create checkboxes without using the desktop version of Evernote.
