Course management system for iPads. Includes a teacher app, which you use to create and edit classes, and a student app. Polling, web browser, course webpage, blog, and assessments. Take notes on readings using split-screen function.
Students submit written assignments via a dedicated email address, and the instructor uses this app to annotate the submission, including text notes and drawing. The app exports the annotated submission as a PDF and sends it back to the student.
Leave text notes for specific people that they only receive at a particular location. Students or teachers could use this to create a treasure hunt in the TL that other students would use.
