TTRS Video is an Android app that provides video call services for sign language conversations. It allows people with hearing disabilities to communicate with others via video calls on their smartphones or tablets with WiFi or 4G/3G internet connections. The app is free to download and use.

To use TTRS Video, the user with hearing disabilities types the name and phone number of the person they want to call, and the app connects them to a sign language interpreter who translates their sign language or typed messages to spoken language. The interpreter then speaks to the other person and translates their spoken language back to sign language for the user with hearing disabilities. The conversation continues in this manner until it is finished.

Overall, TTRS Video is an excellent app for people with hearing disabilities who want to communicate with others via video calls. It is easy to use and provides a much-needed service to a community that often struggles with communication barriers.
