Setting an alarm is a simple matter of opening the Clock app and tapping the Alarm tab at the bottom. Tap the Plus button in the upper-right corner to add an alarm and spin the wheels to set your alarm’s time.
To edit an existing alarm, tap the Edit button in the upper-left corner of the Alarm screen and then tap the alarm you want to adjust.
Basic alarms are one-time-only events. Whenever your alarm sounds and you turn it off, you have to turn it back on the next time you want to use it. If you use the Repeat option, you can have it sound automatically on certain days.
Labels let you differentiate your alarms from one another. Don’t forget to decide which alarm Sound you want to jar you from your slumber. Lastly, to avoid temptation, you can disable the Snooze button.
To delete an alarm, just swipe left on its entry and tap the resulting Delete button.
Bedtime: A More Refined Alarm
While regular alarms are on an as-needed basis, Bedtime is for the start and end of every day.
The idea behind Bedtime is for you to go to and get out of bed consistently, and hopefully improve your sleep in the process (without requiring any additional special sleeping gadgets). Bedtime even includes basic sleep tracking.
Bedtime takes a different approach to setting an alarm. First, tap the Bedtime tab along the bottom of the Clock app’s screen and then enable the Bedtime slider to turn the feature on.
The setup for Bedtime is straightforward. Use the dial to set your bedtime and wake time. Tap Options in the upper-left corner to pick the days of the week for Bedtime to function, a bedtime reminder (15-minute increments, up to an hour), a wake up sound (AKA an alarm), and volume.
At the bottom of of the Bedtime app is a feature called Sleep Analysis. This lets you track sleep quantity versus quality. It will only chart the time you spend in bed, not whether you are actually sleeping.
The overall idea behind Bedtime isn’t about obsessing over your sleep. It’s a tool to help build good sleep hygiene. If you have a routine where you go to bed at the same time every night, and get up at the same time every morning, it follows that your sleep quality should improve.
Other Useful Clock Features
The Clock app isn’t just about alarms and sleep. It boasts three other notable features, assuring you won’t have visit the App Store for anything else clock-related.
Time Everything With Stopwatch
Dedicated stopwatch apps are plentiful and unnecessary. Your iPhone already has one built-in. If all you’re doing is timing a speech or running laps around the track, it should be more than enough.
Stopwatch mode is easily accessible from the Stopwatch tab at the bottom of the Clock app. Your iPhone’s stopwatch features a digital and analog mode; swipe left or right on the stopwatch face to switch between the two.
Its operation is as simple as you would expect a stopwatch to be (with Start, Stop, and Reset buttons). It can also track lap times, and will note your fastest lap in green and slowest in red.
Use the Timer to Count It Down
Just as the stopwatch lets you count up, the timer is for counting down. This lets you know when your break is over, or the moment you’ve steeped the perfect cup of tea.
To set a timer, tap on the Timer tab. Spin the dials to set how long you want your timer to run, assign it a sound, and press Start.
To stop your timer prematurely, tap Pause and then Cancel.
World Clock: What Time Is It… Anywhere?
The final feature of the Clock app is an utter necessity for road warriors, or a simple curiosity to homebodies. World Clock lets you set clocks for anywhere in the world. So, when you need to know the time in California or Calcutta, all you need to do is open Clock and tap on World Clock.
Adding clocks is as easy as tapping the Plus in the upper-right corner, then scrolling to or searching for a location. If you tap Edit, you can delete and reorder your clocks.
All Your Clock Needs Fulfilled
The Clock app on your iPhone is more than capable of fulfilling your most essential time needs. Whether you need alarms, a world clock, or timing activities, it’s got you covered.
If you need anything further than this, there are of course apps that fill certain niches. Timer+ can run multiple stopwatches and timers, while Time and Date’s World Clock offers enhancements like sunrise times and dialing codes. Impala Studios’ Alarm Clock app lets you pick different themes and wake up to your favorite music.
