SplitTimer is a timing app specifically designed for track and field athletes, coaches, and fans. The app has two modes. One provides a stopwatch function which provides overall timing as well as split and lap times. A second mode allows the user to select a running event from a list, and then to collect splits at each lap. The app calculates each lap time as well as predicted final time based on the average pace so far, and also a predicted final time based on the most recent time. Users may send recorded times to themselves or other via eMail.
