There's nothing wrong with as long as there is an intention on both parties to meet and the distance isn't something unfeasable. I've dated a few girls I've met online before. Mostly when I moved back to Rome from Edmonton and mostly girls in England, but plane tickets are dirt cheap so I could affors to see them once a month or so for a few weeks.
I only use those apps for one night stands. I have too much respect for myself to get in to a relationship at this age.
The most haggard beasts I’m seeing is women your age, how they get so broken and old looking at such a young age is bizarre
