How make snoozing iphone alarm go away for today?

Very often by the time I get tothe phone it's lock screen is already on and black so when i wake it up the alarm goes to snooze and i have not found any way to disable the alarm for today unless I go to the alarm settings and switch it off and on again.

Instead of swiping the snooze to the right like you would if unlocking, swipe to the left, then push the x. Done

Before swiping, the screen will look like this:

After swiping left on the "Snoozing" message, you should see:

Clicking on the small cross should then cancel the alarm.

As you already know, if you unlock your phone while the alarm is going off, the alarm is acknowledged and won't sound again until the next day.

If the alarm is snoozing, it seems that the only way to prevent it from going off again is to manually turn it off (and on) again. The only help I can offer is recommending that you unlock the phone by sliding the clock icon where it says "Snoozing" on the lock screen, as that will at least take you directly to the alarms menu.

I imagine that they have this obstinate functionality because people might use alarms for other purposes than waking up, and they might be using their phones for other things and perhaps don't see the alarm.
