Dating apps: do they all have the same purpose?

Hey, guys,
I wanted to bring up a topic that I have in mind lately.

Do you think that all applications to meet people like Tinder or Badoo have the same purpose?
In other words, do you think that all of them are used to find a partner, make friends or have sex?
Or do you think that each one of these apps has a different purpose?

In my opinion, I think Tinder is more suitable for finding a partner and Badoo is more dedicated to looking only for sex. Do you think I'm right?

For example Tinder does not let you send photos, which prevents you from playing to send you sexual photos to give a spicy touch to the talk and however Badoo does allow it.


What app of this type do you recommend me for those of us who are only looking for sex?

Regards.
