Is it just me or the alarm app doesn't work??? It feels like it doesn't go off! Whenever I wake up and check my phone, it shows that the alarm went off but what the hell... I used other apps before like Rise, Sleep Cycle and others without a problem and woke me up right on time. Is this just an ongoing bug in iOS 7 that the alarm clock doesn't go off? Because back in iOS 6, it worked flawlessly.
