Having to install software on my phone to use a service is cringy as hell and is a huge red flag for me. Like when trying to order food from a restaurant or shop somewhere.
It's almost always going to be a automatic no. I just don't trust them. They always want permissions to access things on my phone, which is just pure nonsense.
It's going to take a while for businesses to realize that in order to get a wide audience for the software they are paying for the last thing they want to do is force people to jump through hoops in order to use it.
For every one of 'google maps' there is going to be ten thousand other apps that simply have no benefit from being 'native'.
