Being a college student I often find myself being awake for long stretches of time, and often lose track of what time it is. More importantly, I lose track of how long I have been awake. UpTime is a simple app with one function; keeping track of how long you have been awake. Whenever you wake up, just hit the up button. Then later on when you are rubbing you eyes and mentally exhausted, you can easily keep track of your UpTime. Best of all, the app is free and supported on all iPhones running iOS 5 or greater
