The third mode boasted by the Clock app is a timer that can be used for a wide range of purposes, such as setting cooking times in the kitchen. Use the digit keys to enter the time you want to elapse and then tap the Start button. The display will then switch to a simple timer with options to add an additional minute to the time or stop the timing process.
When the timer reaches zero, a beeping noise will be sounded to alert you. You can also add labels to your timers, which is useful if you have a certain timer stored that you will be likely to use repeatedly, and you can create new timers by tapping the ‘+’ button at the bottom of the page.
