Is it magic? Is it a personal assistant? Nope, its Leaving Work! Leaving Work automatically sends a text to your significant other (or anyone you choose) when you leave work. You simply tell the app who to text, what message to send, and at what times (because nobody cares when you go to lunch!) and youre done. Leaving Work will automatically detect whenever you exit work and will send a message to the person of your choosing so they know your on the way home.
Note: Continued use of GPS running in the background can dramatically decrease battery life.
