So, if you're a road warrior like me you probably have different alarm wake up times when you are on the road than when you are at home. And I can tell you from personal experience that if you leave your work alarm enabled when you are at home, and it just happens to be at 4 a.m., you will probably upset somebody in your house. I just recently became aware of location based alarms within the Samsung Galaxy s4. Now I can have my work wake up calls be different from my home wake up call. Here are some pictures to help you out.
Oh, and my favorite part... The voice snooze/stop so you can basically yell at your alarm to tell it to snooze or stop.
