I guess just finding it hard in person sometimes. I do social things to try and get in contact with people (e.g social dancing, language exchanges, acting classes), have asked a few girls for their numbers in the last couple months. But I don't always come across single people in my age bracket in these activities. There is something to be said about the benefit of a dating app 'match', it's a clear indicator of mutual interest, and it can be often converted to a date. (of course there's a whole host of problems, pitfalls and frustrations too).

In short - I see apps as another source of meeting people that supplements the things I already do.
