The stock alarm clock that came with my Atrix 4G was great--it filled the entire screen, touching anywhere on the screen would snooze it, and in order to dismiss it you had to swipe a slider all the way across the screen. It was virtually impossible to accidentally dismiss it. I LOVED that.
The stock alarm that's on my Atrix 2, which is running ICS (4.0.4), looks exactly like the one on the 4G--until the alarm goes off. The alarm shows up as a small rectangle in the middle of the screen; its 'dismiss' option is RIGHT THERE and can easily be activated by an errant touch. There is no setting to change dismiss to something else, like a swipe. Touch it and you're done.
I've been looking for suitable replacements but haven't found any yet with a slider/swipe dismiss option. Does anyone know of one? There are like a zillion alarm clocks in the market! They don't all include screenshots, or detailed info, about their dismiss options, so without actually TRYING them all...I'll never know!
Right now I'm trying the free version of Alarm Clock Xtreme which is pretty good, and has a plethora of choices for its dismiss option...EXCEPT swipe.
I'd happily spring for the paid version if not for this one omission.
