Blackboard-Stopwatch
This app is a simple stopwatch with very large numbers.
The app has only one button with 3 functions: start, stop and reset.
In conjunction with my USB or 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 USB or Bluetooth-button.
