【實用生產應用app】RingerOn|最夯免費app-綠色工廠好玩App

If you've lost your phone inside your house or office, this is the app for you. It will turn your ringer on based only on a text message and a "password". You configure the key to send to it, and the number to receive it from (or all phones if you want), and it will RingerOn when the phone receives that message. No longer will you have to search through your car, couch and garage just for your phone which is on silent. It even sends back a message to the phone, saying that the ringer has been turned on.

If installed remotely, send message saying "Ringer on", and that will trigger the ringer to turn on.

This might not work with 3rd party messaging apps, such as Google Voice.
