Amazon's Alexa app now works hands-free on Android and iOS devices

Alexa allows hands-free control of all manner of devices, but there's been one glaring exception: its own smartphone app. Amazon has finally brought that feature directly to Android and iOS devices via a new update. All you need to do is open the Alexa app, either manually or (ironically) via Google Assistant or Siri to stay hands-free. From there, you can control Alexa with your voice as you normally would on an Echo or other device and ask it to play music, control your smart home or anything else Alexa can do. The Alexa assistant has always worked on the app, but until now, you needed to touch the Alexa button on the bottom control bar for voice control.
