In answer to your second question, I am an elementary school teacher of 13 years & am developing a completely free (ad-free too!) reading log app for iPhone, iPod, and iPad. The app should be up on Apple's app store in early December 2012. I'll be posting screen shot previews on my blog at http://youlogreading.wordpres... I'm hoping it will find its way into elementary and middle school classrooms. There'll be options for goal-setting, stat graphing, and sorting of books by genre, title, author, lexile, & publish date.
