      stretchly is a cross-platform electron app that reminds you to take
      breaks when working on your computer. By default, it runs in your tray
      and displays a reminder window containing an idea for a microbreak for 20
      seconds every 10 minutes. Every 30 minutes, it displays a window
      containing an idea for a longer 5 minute break.
