AlarmDroid is a simple app that will give you access to as many alarm clocks as you want on your Android device.
You will be able to set any sound for the alarm clock, even vibrate, even though the best thing is always to select whatever song you have memorized.
The ability to put a widget that will tell you exactly what time the different activated alarm clocks will go off is also very intriguing.
AlarmDroid is a very useful app because today almost the entire world uses its cell phone as an alarm, and this one is excellent.
