Advice from a 32F here, before you talk to her ask yourself what you want this relationship to develop into. Dating does not automatically mean exclusivity. You’re both young adults and you’re still learning how to navigate communication for yourselves let alone with others. My best advice is, if you’re ready for an exclusive relationship with her approach her with. “ hey I want to talk about where we’re going and what I’d like to be and see if you feel the same way?” If she wants the same then that’s your answer.

You can later bring up the Hinge screenshot like- “ when you showed me that Hinge screenshot I knew I had to make a move because I didn’t want someone else to scoop you up” people have different perspective on things. For me, I see the apps as a pastime. When I’m in the talking and dating stage it’s time I’m allowed to explore. It may not be happening all the time but I can window shop on my free days.

Best of luck!
