Quick background: I've been on and off dating apps for a couple of years and I still haven't found a clear answer.
One thing I keep running into is that no two people seem to agree — everyone has a different platform they swear by, and I suspect it depends a lot on location, age range, and what you're actually looking for.
Any recent experience (within the last year or so) would be most useful since things seem to change quickly in this space.
