If you have ever been in a situation where you've needed to time something, or see how long it takes a friend to perform a certain task, the taking out your iPhone, launching the Clock app and jumping into the Stopwatch time is in itself a time consuming task. Granted, this may have only happened to an extremely small subset of iOS users, but a problem solved is still a problem solved, and thankfully, this niche problematic situation has been eradicated for jailbroken users thanks to the Stoppur tweak.
