The app works as a service which reply to special sms messages by sending back location of the device.
There are two cases for using it:
1. When you need to know where is your family member or friend which password you know.
2. When your device is lost and you have to find it, but Internet connection is not active in device.
There are two operation modes:
1. You can send sms with app name and password from any device and you will get back the location in case of emergency. In this case password will be in plain text, so you should delete sent message manually if you do not want the user of this device know your password.
2. You can use the app to retrieve location of a device by sending sms with encoded password.
Password dialog appears automatically on launch now.
