AppAdvice has teamed up with Gorillized in order to offer you a chance to win one of six promo codes for Outline+ ($14.99) for iPad.

By combining Microsoft’s OneNote file format, convenient cloud storage, and an iPad-optimized user interface, Outline+ is able to become one of the most efficient note-taking apps in your productivity toolbox.

Notebooks can be as simple or complex as you need, such as page after page or separated into sections with multiple pages each. Along with standard text input, pages can contain images, be identified as favorites, and searched. As a bonus for visual appeal and improved navigation, there are nine book cover images and 16 colors to choose.

To keep all of these projects easily accessible and synchronized, Outline+ offers Dropbox, Box, and iTunes File Sharing integration. Effortlessly import and export notebooks manually as well as have them automatically synced.

In the recently released Outline+ v2.3, Gorillized has added notation tools, consisting of various colored pens and markers, plus passcode lock in response to user feedback. The four digit passcode is enabled and disabled within Settings, located under the information menu, and locks the app whenever it is closed.
