I have no doubt Google Assistant is better than Siri. But how is this useful at all on iOS? Who is going to open an app just to use the assistant?
People like me who have given up on Siri. She is absolute garbage.
Dictating a text to my wife:
Me: Send a text to NAME that say's I'll be home by 5.
Siri: I'm sorry I don't recognize NAME. [even though it was recognized earlier]
Me: Repeat.
Siri: I'll send a text to NAME that says Beehive.
Me: Repeat.
Siri: Sorry, I didn't get that.
Me: Repeat process five times until it works.
Finding the phone number of a local framing shop:
Me: Call "NAME Framing Shop"
Siri: Here are 3 framing shops near you. [50 miles away]
Finding a Vietnamese restaurant:
Me: Find All Chay Vietnamese.
Siri: Sorry, I don't recognize that.
Google finds the last two every time, the first time.
