I have recently decided to move all of my school medium into electronic format, and this includes my planner. Everyday, I find myself forgetting homework because I tried different methods of writing them down. This iPhone app is just incredible... It's called iStudiez Pro. At $3, it's not cheap, but the app has an incredible interface and multiple features. However, second generation iPod Touchs or iPhones/iPhone 3Gs (Plural 3G), you will experience a lot of crashing. For those who have newer devices, try it out! It's even iPad universal, but I can't imagine who would want to carry around their iPad instead of an iPhone...
