Tell Google what you want to do, make phone calls, get directions, send text messages, set reminders, ask questions, play music and movies, try more voice action etc. by telling Google by your own voice, this is the most useful app, you don’’t need to type or dial on your screen, just command Google what you want to do.
I love it and I recommend everyone to try this app. It recognized my voice and no other person can command or use my phone.
