5. Uninstall Third-Party Alarm Application

You may have an alarm application conflict on your iPhone. It is better to use one application, and we advise you to use the default app that came in with your iPhone. A third-party application may not sometimes work because of pending updates. The need to constantly update an application is troublesome while the default app is tied to your device overall update, which can only be done occasionally. Here’s how to remove the third-party application in your iPhone:

  1. Go ahead and find the icon of the third-party alarm app that you want to delete in your home screen.
  2. Next, tap and hold the app icon until it starts to wiggle, and an (x) appears at the upper left corner of the icon.
  3. Then tap the (x), then tap Delete option to confirm the process.
  4. Now, if you have more third-party alarm app, delete it by repeating Step 2.
  5. Finally, if you are finished deleting all the third-party alarm apps, tap Done at the upper right corner of your screen.

Now that you have removed the application conflict, your default alarm app in your iPhone should work properly. But if you are still experiencing the issue, the next method might resolve the issue.



6. Restart the Device

If a certain device has been running for a very long time, it can sometimes not function properly. This is due to the overloaded temporary storage of the device. Your iPhone is not an exception and can suffer the same problem. However, you can always refresh the device by doing a restart process. Here’s how you can do it:

  1. First, go to your iPhone’s Settings.
  2. Then find and tap General, then tap Shut Down.

Shut Down iPhone


  1. Lastly, slide the Slide to Power Off button to confirm the process, and your iPhone will subsequently begin to power down. Give it a few seconds, then turn your iPhone back on again.

If you cannot do this, you can always force restart your iPhone. Now that you have refreshed your iPhone, your alarms in the Clock app, along with the other default applications, will work properly. But if your alarms are still not working properly, you need to check out the next method.

  3. Next, tap Settings, then General, then Software Update.

8. Reset All Settings

Sometimes we tend to forget the setup that we made in our devices from the time we first got it. We also do not know if family members or friends that borrowed your phone have messed up with it.
