AppAdvice has teamed up with Life Lab in order to offer you a chance to win one of five promo codes for Book Writer ($3.99) for iPad, iPhone, and iPod touch.

Whether publishing a story, writing an instructional guide, or assembling a collection of photos, the e-book format is an easy and cheap way to distribute exciting content. You could use a feature-rich app like iBooks Author, but that requires a computer and may even be overkill for many projects.

Instead, Book Writer allows construction of simple yet wonderful e-books and PDF files all while on the go, especially if combined with any of the many video and photo editing apps for iOS. In fact, Book Writer features four different layout choices, object resizing and positioning, the option of background music, text styling, exporting as ePub or PDF, as well as support for importing images, videos, and audio.

Not only can you create an e-book or PDF on the go, but the process is painless. Nearly every action is a basic one or two finger gesture. Use single finger taps to select with a hold to highlight text or move objects. For resizing and rotating, just use the standard two finger pinch, expand, and twist gestures.

When all is complete, you can keep the project in Book Writer for later editing, print it, send it via email, transfer it using iTunes File Sharing, or send it to one of your favorite e-reader apps.

To have a chance at winning one of the five Book Writer promo codes, leave a comment below telling us just one of the ways you could utilize this handy book creating app before July 15 at 11:59 p.m. PDT. Only one entry per person is allowed. Please be sure to also check your junk email boxes so that you won’t miss out if you win.
