Guardian.Angel

When you setup a message, Guardian.Angel will backup your message to our server. If you cannot dismiss your message before preset send time, Guardian.Angel server will help sending out the message to your recipients so that they know you are in trouble. You can also attach your location in the message to let your audiences know where you are to get you out.

Using this app is totally free, but if you appreciate our work it will be great for you to support us in In-App Purchase.
