Abstract: A method for using a mobile software application for deleting or recalling unwanted messages on a mobile device before it is delivered to the intended recipient is provided. The software application operates by running on top of the resident messaging application on the mobile device. For example, the application caches the message for specified amount of time and thereby sets a length of delay. The user has the application on the mobile device and the message is composed on the OST application and the application software keeps the message in a buffer for a predetermined amount of time after the user selects to send the message such that if the user regrets sending the message, it can be deleted or recalled before the message leaves the mobile device. Other advantages that are understood from the present disclosure will further be apparent.
