I've been using ToodleDo to organize my homework, exams, etc, along with 2Do on the iPhone. It works pretty well, but I'm wondering if there's something better out there? Something specifically designed for classes? I ran across an iPhone app called iStudiez Pro that looked pretty interesting. I'd like something that has a computer program, and iPhone app, and preferably a web interface too. iCal integration would be nice. Any suggestions?
