What's a decent iOS app for parents to keep tabs on their kids' grades and attendance without having to call the school every five minutes?

Look, I'm a chef, not a freakin' guidance counselor. But even I gotta know if my kid's failing algebra. PowerSchool Mobile, it's not pretty, but it gets the job done. It's like a no-BS stockpot – functional. You can see grades, attendance, teacher comments… the whole shebang. No more guessing games or relying on the kid to 'remember' to show me their report card. This app is quick enough to check during a lull in the dinner rush, and that's saying something. Plus, it beats having to actually talk to someone on the phone. I can see if he's ditching class from my phone while I'm prepping the sauce. That's efficiency, baby! Most of these education apps are garbage, but this one's actually practical.
