Android: Last Message is a simple app that texts, emails, tweets or sends a Facebook message to the friends you specify when your phone's battery is about to run out. So if your family and friends are unable to contact you, they will know why.
Last Message takes away some of the stress of a dying phone by notifying your spouse, roommate or other important contact that you will be incommunicado while you find some juice. You can set what battery level constitutes "low", send one of many types of messages, and even have it automatically turn on. Check out the video above or hit the link below to try it out.
Last Message is a free download for Android devices.
