What's a good iPhone app for keeping tabs on my students' grades and attendance, you know, without having to lug my laptop everywhere?

Okay, so I started using Campus Parent a few months back, and honestly, it's been a lifesaver. It's like having a teaching assistant in your pocket, though a digital one, of course. I can quickly check student grades, see who's been absent (again!), and even send out quick messages to parents. Now, finding the settings took me a minute – why do they hide the settings button there? – but once you get the hang of it, it's surprisingly intuitive. My students showed me a trick or two, too! It's especially handy when I'm at a basketball game and a parent asks about their kid's grade. Beats saying, "I'll have to check when I get back to my computer!" It's not perfect, mind you, but for a guy who still prefers paper grading sometimes, even I could figure it out. It's made keeping track of everything much easier, and that's a win in my book.
