If you ever take quick sprints and want a more accurate way to time yourself rather than trying to synchronize the start button with when you take off at a full sprint, then you should check out a new free jailbreak tweak called Sprint Timer by iOS developer Brogan Miner.

With this tweak installed, rather than trying to time your tapping of the start button just right with when you take off at a full sprint, you can tap and hold on a new yellow-colored Sprint button from within the Clock application's timer interface. The timer will not begin until the accelerometer senses movement that would normally be your arms moving while sprinting.

During the entire sprint, you must keep your thumb or finger on the yellow Sprint button. As soon as you let off of the button, the timer will stop, showing you a very accurate depiction of your sprint time.

The tweak is actually a very good idea and is brilliantly implemented. The only thing you would really have to be careful of is accidentally dropping your iOS device while sprinting and keeping your thumb or finger on the Sprint button. Since the tweak uses the accelerometer instead of your mind to time your start, it's more accurate and reliable for timing your sprints.

If you would like to give Sprint Timer a try, it's available for free right now in Cydia's BigBoss repository. It's worth mentioning that the tweak is open source and the source code is available on GitHub at this link. The tweak has no options to configure and requires iOS 7 to be installed.
