This is a simple yet powerful app that allows you to locate your phone remotely by text-message.
It's very easy to use. All you need to do is a set a password. From then on, your phone will reply back to any text-messages of the form "Locate: password" with its current location.
Make sure that:
1. You have your GPS enabled. Don't worry about your battery, this app is smart about being power-efficient.
2. You include a space between "Locate:" and the password when sending this phone the text-message.
3. You type the password exactly as it is - it's case sensitive.
