The app runs directly in your web browser

Add Times is a simple calculator app that adds times given in hours and minutes. It helps with the recording of machine running times, or with the addition of flight times in your pilots’ flight log. The program has been written by Stefan Kebekus, as a project of Akaflieg Freiburg, a flight club based in Freiburg, Germany.
