How to Use iPhone Stopwatch
The iPhone comes pre-installed with a stopwatch feature in the Clock application that allows users to time specific events. The stopwatch feature is a convenient way to record the duration of events and is accurate to a tenth of a second. There is also a lap feature that allows users to track a repetitive event--such as running a lap--and separately record the time that each lap takes. The iPhone stopwatch is extremely easy to use and takes just moments to prepare.
