What Did We Do Today? (WDWT) is a mobile platform for sharing class events with teachers, parents, and students to track assignments, reminders, homework, etc.
Platform similar to SubText that allows teachers to publish PDF, ePub, Word and Excel & classes / students can read collaboratively on any device. Documents are published using HTML5 = iPad friendly.
This app could be a great review for a basic physics class. It includes a study guide and covers most common units such as motion, vectors, energy, and optics.
eBackpack offers storage and collaboration features to individuals, classes, teachers, and schools. Now, there is an iPad module to help manage workflow and student portfolios. The pricing is quite affordable.
This site provides both a social network for your class as well as iOS/Android/Facebook apps to support learning outside of school. Unlike other study apps, this one encourages teachers and students to collaborate and engage via their Study Hall social network
