Is Tinder just for hooking up?

I'm just wondering if Tinder is only for hooking up. I ask because everybody seems to assume that. Except for the girls I match with on there. The girls I talk to don't act like they want to hook up. I ask them what they're on there for and they say they want to make friends and they aren't into one night stands. Are they being modest? So I don't know who is right. Thoughts?
