Next, you will be asked if you want to add an alarm sound for when your interval timer finishes counting down – this is completely optional so you can simply select None if desired. Once you have chosen your desired duration you can tap Set at the top riht corner of your screen to confirm your selection. You can choose from preset intervals such as 1 minute or 5 minutes, or enter a custom duration by tapping Custom at the bottom of the list. You will first be prompted to enter a duration for your timer. Tap this tab to open up the timer menu where you can customize your settings.

You will see a tab labeled Timer at the bottom of the screen. First, open the Clock app which is pre-installed on all iPhones. Setting an interval timer on your iPhone is easy and straightforward. One of the more useful features that comes with every iPhone is the ability to set an interval timer, which can be very helpful in keeping track of tasks, activities, or just about any other timing need you may have. Operating System scheduling or the running of other callbacks may delayĬonst fs = require ( ' fs ' ) function someAsyncOperation ( callback ) // the callback is called before `someAsyncApiCall` completes.The iPhone has become a staple device for many of us, allowing us to stay connected, take photos and videos, and perform countless tasks on the go. Scheduled after the specified amount of time has passed however, Timers callbacks will run as early as they can be May be executed rather than the exact time a person wants it toīe executed. ).īetween each run of the event loop, Node.js checks if it is waiting forĪny asynchronous I/O or timers and shuts down cleanly if there are notĪ timer specifies the threshold after which a provided callback
