Users can activate the assistant by voice commands or through the app interface, and it also allows for integration with Google Assistant for added convenience.

The app provides extensive functionality, supporting various Alexa features such as making phone calls, sending text messages, and controlling smart home devices. Users can set reminders, timers, and alarms, and access local information or their calendar entries.
