App: Classroom Timer

Genres: Wirtschaft, Bildung

Ideal for timed workshops and classroom assignments. Any image you paste on the clipboard is displayed on the second screen, and can be overlaid by a clock, timer, or stopwatch.

You can even take a screenshot of the screen you are projecting on with Shift-Command-2. Try it from PowerPoint or Keynote. It takes a snapshot of the currently projected slide, and uses it as the Classroom Timer background.

Works best when you disable mirroring.
