The low-tech guys offer a range of productivity apps designed to simplify tasks and workflows on macOS. By leveraging automation and utility tools, their apps aim to streamline user experience. The concept is simple: add a trigger (when I connect my headphones), set an action (switch audio output), and as if by magic, it just happens. Actions can receive data about the event, like the headphones name, the screenshot file that was just taken, the calendar event that starts in 5 minutes, the battery level etc.
