4. iStudiezPro

If you are always going crazy marking things down on your paper calendar on the wall but then never making your appointments on time because you can’t bring it with you everywhere, then iStudiezPro is the app for you. This great app keeps track of deadlines, your grades and much more. It works on all Mac and Apple type iOS devices, including iPhones. It also comes with the ability to sync up all your info on the Cloud, as well as uses iCal integration. It’s not free, but it only cost $2.99. However, there is a limited version you can get for free, but it doesn’t do as much as the other one.
