Here are some apps that may be helpful to you. Link to the apps and you can manage your course load, prepare for exams and even get you to class on time.

Rescue Time

Rescue Time offers a detailed look at how you’ve spent your time—the good and the bad. This desktop application runs in the background, tracking everything you do on your computer, and delivers a report on how you’re spending your time. The free version tracks the time you spend on websites and applications, lets you set goals and sends weekly reports. At $9 per month, it adds the ability to track time away from your computer and lets you block websites that may affect your productivity.

Math Alarm

Want to make sure you get to class on time and squeeze in a little extra math practice as well? That’s exactly what Math Alarm, a free iOS app, can help you do. Set the alarm for the time you need to rise, and you’ll have to answer a math problem in order to turn it off. The problems aren’t tricky but they are enough to awake your brain so that you’re more likely to wake up.

Cliffs Notes

Teachers hate them, students love them. The Cliffs Notes Study Guide app is free for iOS devices, but actually available only for some contemporary well-known novels. If your course load includes another classic novel, you’ll have to pay $2 for each study guide you need. The available titles include a wide selection, ranging from The Outsiders to Paradise Lost and Their Eyes Were Watching God, but students in need of help with some lesser known titles may be out of luck.
