Teachable is a nice free iPad app that educators are using to make their lives in the classroom easier. It's a very easy to use productivity app that helps teachers plan, track, and organize their classroom from their iPad. Educators can manage, track, assess, and grade
their students as well as plan their day, week, or month. Teachers can even attach images or annotate through notes to help assess students in real-time.
