The Don't Leave It! App makes sure you don't forget your stuff. Perfect for perpetually forgetful people who often fail to remember to bring their personal effects with them, the yet to launch iOS app is designed to stop you from leaving a place without your belongings.
Whether you don't want to forget your keys at work or wallet at home, Don't Leave It! is easy to customize based on item and distance. The patent-pending application has 80 default items, or you can add your own. You can also set your distance perimeter so you won't get too far without your stuff. When you walk away, you will be sent a notification, creating a virtual barrier around your things.
Although this will deplete the Lost and Found, it may not be effective if it's your phone you leave behind.
