Deleted alarm still going off daily

Hi Kristvc,

Thank you for using the Apple Support Communities! I understand you no longer have any alarms set up in your Clock app, however previous alarms continue to engage. I am happy to help out.

Let's start troubleshooting with some basic steps first:

-Be sure this alarm is not related to the Bedtime feature in Clock: Use Bedtime to track your sleep on your iPhone - Apple Support.

-Force quit your Clock app: How to force an app to close on your iPhone, iPad, or iPod touch - Apple Support.

-Then, restart your iPhone: Restart your iPhone, iPad, or iPod touch - Apple Support. 

If the alarm(s) continue to engage after the above steps are completed, this may be related to your iOS software, or a third-party app installed. If you can rule out the relation of these alarms with the installed apps on your phone, I would recommend attempting to reinstall iOS first using recovery mode, which preserves your data: If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support. It is still recommended to create a new backup before taking this step.

If the issue remains after attempting to reinstall iOS, the next step would be to restore your iPhone and set it up as new (no backup) to test for the same alarm behavior: Restore your iPhone, iPad, or iPod to factory settings - Apple Support. Keep in mind, if you have any data turned on to sync to iCloud, you can still sign back in under iCloud in Settings to get that data back at least. If the alarm stops after your phone is set up as new, the issue is resolved. You could attempt to restore the device from a backup again, but if the issue returns after restoring from a backup, we know the phantom alarm lies within that backup data and you should not use the backup on your iPhone.

If you need continued support, feel free to reach back out.

Take care.
