From the developer:
BasicTimer is an easy-to-use timer application for full screen usage. This basic timer is developed having in mind simple requirements such as the ease to project in full screen, a strong contrast for poor video projectors; and quick launch. To facilitate a fast launch, the keys of the keyboards correspond to pre-defined durations.
