Tango Tango IoR is a free Android application developed by Tango Tango that provides a next-generation two-way radio app for radio users in various markets, including police, fire, emergency medical services, healthcare, manufacturing, utilities, education, and more. The app offers push-to-talk (PTT) group communication with other Tango Tango users, GPS tracking, and secure messaging to individuals or groups.

The app can be integrated with any existing two-way radio system, allowing users to transmit and receive with their existing radio users from their Android devices from anywhere in the world. However, the app is not intended as a complete replacement for a two-way radio in critical situations. The availability of the app will depend on a cellular or wifi network.

Moreover, the app may use the location of the device even when it isn’t open, which can decrease device battery life. Nonetheless, this location reporting can be disabled.
