SMSsync is a simple SMS to HTTP sync utility. The mobile app turns any Android phone into a local SMS gateway that syncs to the web. SMSsync supports filtering text messages by keywords and can transmit the text message to a configured callback URL via HTTP POST request. The application basically allows you to use your android phone to filter, dispach and forward SMS to other phones, websites or platforms.
