Apple’s Clock application includes a stopwatch, but it is lacking a very important feature: the ability to save stopwatch times.
A new jailbreak tweak dubbed Stopwatch Pro by iOS developer Jailpod makes it so you can actually save times that you record in the stopwatch. As shown above, the tweak adds a new Save button to the stopwatch interface. Tapping the button will log the times involved to the new Saved tab you see at the bottom of the application.
Moving to the Saved tab, you will be able to see all of the logged times you have saved. They are dated so you can keep track of when the times were recorded. When empty, the log will say, "No Saved Times;" however, if there are saved time sections, you will see them. You can tap on the time sections to see the individual laps:
You can delete any times that you save by swiping on them to reveal a delete button, or you can tap on the Edit button at the top of the application to bring up a deletion interface.
In the event that you want to create a new section, Stopwatch Pro supports that too. By tapping on the Add button in the editing interface, you will be able to input a new name for a new section that you can use to organize your times:
Stopwatch Pro doesn't have any options to configure. Anyone that takes advantage of Apple's built-in iOS stopwatch should grab this tweak for the added functionality, as it never hurts to be able to keep a record of your recorded stopwatch times. If you want to give the tweak a try, it's available right now in Cydia's BigBoss repository for just 99$ and is compatible with iOS devices running iOS 6.
