Follow your favorite places on Google Maps on iOS:

As of now iOS users can enjoy what Android users have been enjoying. Now iPhone users can stay up to date on their favorite places right from the Google Maps app on iOS.
The effort is simple as well, simply search for a place—a new restaurant in the neighborhood, Taco place that your friends rave about or just like me, for a film processing store—and tap the Follow button. You’ll then be able to see important updates from these places in your For you tab so you can quickly learn about upcoming events, offers and more.
In the reverse, places and businesses all over the world can see their followers in the Google My Business app, and actively post helpful information for their followers to see. The Follow button starts rolling out on iOS today.
