...Inspired by the Minutes widget from Nitram-nunca, this Timer provides a clean and simple yet effective timing device that can be quickly accessed on your Mac computer. It's very easy to use- simply drag the blue arrow on it to set the timer, and release to get it started. You can also pause the timer with just a click. When the time is up, the timer will let you know with a nice little notification and sound. To create a new timer, just type in CMD+N.
The Timer-app works with macOS versions 10.11 and above.
