Sometimes it's hard to maintain focus on what the task at hand is, especially with so much fun stuff on the internets.
So, to combat this problem, I quickly threw together
Scheduler. This is a little app that allows you to put in
how many blocks (like classes in highschool) and how long each block is. Then, it will have an alarm go off after each block is done.
Then, it gives you a break of your desired length.
