Ultimate Alexa is an application that allows you to easily access and use Amazon's Alexa virtual assistant on your phone. You can wake up Alexa by saying the wake word "Alexa" or tapping on a button within the app. You can also activate Alexa through your phone's notification area, a resizable widget, or by using the Google Assistant and saying "OK Google. Start Ultimate Alexa." With the Pro version of the app, you can even wake up Alexa by shaking your phone or using the Bixby button on Samsung devices. On Wear OS watches, you can simply tap on a button to start talking to Alexa. The app also gives you control over when it will listen and respond to your commands, and you can choose from different Alexa voices. Ultimate Alexa supports all of the features that Amazon allows, including making phone calls, sending text messages, playing music and audio files, setting reminders and alarms, controlling smart home devices, accessing local information, and much more. However, some features may be limited depending on your location and the availability of certain Alexa skills. If you are an Amazon Echo device owner, please note that this app is not the same as the official Alexa app that is used for remote control and settings. The app may also prompt you to enable an accessibility service, which allows it to replace the Bixby assistant on your device and share the microphone with other apps. Overall, Ultimate Alexa is a comprehensive and convenient way to access and use Amazon's Alexa on your phone, with a variety of options for waking up the assistant and full support for all of its features.
