This stopwatch can be used for model glider contests. In a model glider (F3K and F3J) contest, a pilot can fly his plane a number of times within the 'worktime'. Using this application, each successive flight can be recorded while the working time decreases. When the working time ends, a signal is given. Tap anyhwhere in the screen to start or stop a flight. Tap 'Start' to start the countdown timer for the Worktime. Tap the Info button on the down-right corner to edit the duration of the Worktime. This is a free, lite version. The Pro version includes several enhancements including a 'talking timer'. With this talking timer the pilot can hear when the worktime will end. The Pro version also stores the recorded flights in a database on the iPhone.
