I've just got an iPhone but I'm a bit confused. Do I need to download Google play store or?

I've just got an iPhone today and I just need a little help. Do I need to download Google play store or do iPhones have something different?

Google play is for androids.

IPhones don't have Google play, that is for Samsung or other. They should have the app store, of which the icon is blue with a white paint brush, pencil and ruler in an A shape.

No google play for you my friend. You have the Apple App store

IPhones have the App Store. Google Play (which was derived from the App Store) is the equivalent on Android phones.

Appstore icon is already on your screen.

There should be an App called the "App Store" that is what iPhones have instead of the Google Play Store. Unfortunately, this means that any app you paid for on the Play Store you will have to buy again.
