Boyfriend has dating app on phone?

So my boyfriend of 3 years and I were in the car a few days ago, and when he asked me to put on a song on his phone, I accidentally saw that he has a dating app on his phone. I did not open the app. I didn't ask him about it then because there were other people in the car as well and I haven't seen him since, but I am now kinda curious why he would have that. I mean, could it be that he has such an app as like a dare or something with friends? Or could you think of other reasons why someone would have a dating app?

Ofcourse I know I should talk to him about this when I see him next, but I don't want to be too judgmental. I mean, it could be nothing right?

So basically my question is: are there any other reasons why my boyfriend would have a dating app on his phone?

by the way, I haven't checked the app so I don't know if he actually has an account or not
