"Teacherkit for iPad, iPhone and iPod touch is a free app (iTunes link) for teachers that many iPad/iPhone users will find extremely useful in the classroom. This app, formerly known as TeacherPal, claims to be the “perfect teaching companion” for teachers. I would agree; I have used this app for over a year now, and have been very satisfied with what it can do. The latest update at the end of summer has brought with it many improvements."
