Team Talk’s development has been driven by market research. In response, we have added the features found most important to first responders. Sights, sounds, vibrations, and customizable features that can be changed on the fly have all been integrated into Team Talk. This is a functioning Push-to-Talk mobile application. Users can seamlessly change channels and administrators can easily add new users. The app improves efficiency of data delivery to end user and is built for growth and scalability.
