Blackboard-Stopwatch This app is a simple stopwatch with very large numbers. The app has only one button with 4 functions: start, stop, pause and reset. In conjunction with my Bluetooth device and a photocell it can be a good display panel for any type of race. In this way, the use has practically no limits. Advertising can be deactivated via the "In-app purchases" option. For the start/stop can be used an external Bluetooth-button.
