Fitness app on iOS 15?

Hello,
it's no big deal, but I woke up today and there's Fitness app on my iPhone? I thought it's iOS 16's feature. It wasn't there yesterday.
Did anyone else notice it?

It’s only an addition for users that don’t have an Apple Watch. If you have an Apple Watch the fitness app has always been there.

I feel stupid now. I didn't it before.
