Create a count down to a certain day (e.g. a birthday, presentation day, appointment, etc.), or create a timer for a set duration (e.g. 30 minutes, 2 hours, etc.). Click "switch mode" to choose between how you want to use the tool. Countdown Ready will notify you when time is up. You can pick type of notification you want to receive: either a subtle side notification or a more apparent alert box pop-up. You can also turn the sound notification on/off. Access the Countdown Ready options menu by right-clicking on the Countdown Ready extension icon and clicking "Options."
