A 2 week free trial is included. After the trial, a purchase is needed to use it long term.
A Simple Voice-Driven Interface - No Car Mount Required
A simple, non-distracting, interface allows you to keep your hands on the wheel and your eyes on the road. No tiny button presses are needed. You can wake up the app to accept a command by simply saying a trigger phrase such as "Hello Android". A mostly-black display reduces battery usage on devices with AMOLED screens.
Hands-Free Text Messaging
Choose how you want to handle incoming messages while driving. You can send an automatic reply or have the app read out your messages and give you a chance to respond by voice. You can also compose a new message at any time. The app supports your cellular provider's SMS/MMS service, and provides optional add-ons for Facebook Messenger, WhatsApp, and Google Hangouts.
No Need To Worry About Speech Recognition Accuracy
No speech recognition system is perfect. If a word or two is missed when dictating a SMS/MMS message, the app can send an audio attachment of your speech along with the text. If the receiver isn't sure what you said, then the audio can simply be played.
Hands-Free Phone Calls
Choose how you want to handle incoming calls. You can ignore them so you're not disturbed, send an automatic text message reply, or announce the call and optionally answer. You can also place an outgoing call using a simple voice command. Calls will automatically use your vehicle's Bluetooth system or the phone's speakerphone.
Simply say something like "Navigate to Walmart", and the app will send your destination into your navigation app, which will start navigation automatically.
Music and Media Player Control
Use voice commands and simple screen taps and swipes to control music and media players such as Pandora, Spotify, iHeartRadio, Google Play Music, and many more. If supported by your player, you can even use voice searches. For example, say "Play Michael Jackson" to hear a classic song from the King of Pop.
When a new text message or phone call arrives, the app will automatically pause playback, allow you to handle the message or call, and then automatically resume playback when you're done.
Kindle and Audible Books
Because the app links to Amazon.com's Alexa voice service (just like their Echo line of devices), you can have any book in your Kindle or Audible library read out to you - even Kindle books with no matching audio book.
News, Weather, Sports, and Traffic
Get a summary of current news stories (which you can customize by category and news source), learn how your favorite sports teams are doing, get weather forecasts, and check on your commute, using nothing but voice commands.
Review your calendar entries and add new ones. The app makes use of Alexa's ability to link to your Google calendar.
Through Alexa, you can set timers and alarms, and access to-do and shopping lists.
You can ask Alexa questions on a wide variety of topics, including: TV shows and movies, music, math, spelling, geography, time, and have it read Wikipedia entries.
Access the Full Power of Alexa
From your vehicle, you can remotely control smart home appliances, buy items on Amazon.com, and gain access to even more features through Alexa "skills" provided by other developers.
Limitations for Android 4
The app will run on Android 4.4 (Kitkat) or later, but access to Alexa requires Android 5 and up. You can still access the communication, navigation, and music features.
