Forget to grab your umbrella? This app will remind you to grab your forgotten item the moment the GPS tracking system notices that you are leaving a particular location and remind you to grab the item. For example, while you are home, you realize that you should grab a pair of gloves when you leave the house in an hour. So, you set the app to remind you to grab your gloves. When the GPS tracking system notices that you are leaving your house, this location based app will alert you to grab your gloves before you have left your driveway. The app can be used in public locations too. You will never leave your umbrella behind in a restaurant or office again. Even if the reminder works just once, it will have paid for itself!

Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life!
