I didn’t think the question is what your favorite map app is.
The OP question is, does everybody use Google Maps.
The answer is NO. It has to be downloaded from the app store. There are a lot of people who may not even know about the app. I know when Apple Maps came out (2012) it wasn’t very good, and Apple got a lot of heat for dropping Google Maps (If you remember it wasn’t even available to download).
But it works okay now, and for many users(referred to as “weirdos”), it does what they need it to. I had both for quite some time, but when I did some house cleaning I deleted Google. But I don’t use any map app very much as I go to the same places most of the time.
A more important question is what does the native link do if you don’t have Google Maps installed?
Not knowing the link you are using.
This link from Walmart:
<a tabindex="0" class="store-directions-icon-link store-icon-link pull-left" href="https://www.google.com/maps/dir/?api=1&destination=1825%20W%20Bell%20Rd%20Phoenix%20AZ" target="_blank" data-target="2.31" aria-label="2.31 miles away, directions"><i class="elc-icon elc-icon-direction"></i><span class="store-icon-link-text"><!-- react-text: 85 -->2.31<!-- /react-text --><!-- react-text: 86 --> mi<!-- /react-text --></span></a>
Will open The google maps app if it’s installed, but if not will open google maps in a new browser window.
Now I just tested this with and without Google Maps installed on my IPad. With Google Maps it launches the app. without it opens
www.google.com/maps with the address.
