TravAlarm is an iPhone app that allows you to set a location-alarm. Now you can kick back, close your eyes, and take a quick power nap during your morning commute and relax knowing that you won't miss you stop because TravAlarm will alert you when you've reached your stop.
Even if you don't want to take a nap, TravAlarm is fantastic for closing your eyes, relaxing, and listening to music during your commute. Unfortunately for me, my commute involves me behind the wheel, but once I'm able to to take advantage of Denver's light rail, you bet I'll be using TravAlarm!
