Convo AU is a free Android app developed by VTCSecure LLC, a Deaf-owned and operated Video Interpreting Service provider. It provides a natural communication experience for deaf and hard of hearing people to connect with others in the same room or over a phone call. The app requires an active Convo Australia account to be used properly.

One of the best features of the app is the ability to connect with anyone through its highly qualified Auslan interpreters. The app also allows users to connect with any of their contacts with just one click, and to receive video messages in their email inbox when they are not available to take calls. Additionally, Convo Australia customers can make free peer-to-peer calls, connect directly with listed Deaf businesses, or connect with other listed businesses through the app's interpreters free of charge.

The app also provides a history of past incoming, outgoing, and missed calls, an internal directory for Convo Australia users to connect directly with the company for support and other inquiries, and compatibility with SIP and H323 standards. Moreover, the app prioritizes WiFi connections where possible, provided that the device's WiFi is enabled properly. Overall, Convo AU is a valuable tool for Deaf and hard of hearing individuals who want to communicate with others seamlessly and naturally.
