BasicTimer at Mac App Store analyse

When I run a course, I like being able to project a timer, big enough, to help my trainees manage their time during an exercise. In developing this basic timer, I had in mind the following requirements: - a timer - simple (no setting ...) - easy to project in full screen - with a strong contrast for poor video projectors - and quick to launch. To facilitate a fast launch, the keys of the keyboards correspond to pre-defined durations. eg: Type "P" then "Enter" to start a 20-minute timer in a flash!
