I think this is an interesting topic.
I have heard a lot of people recently talk about the choice onslaught as a bad thing in that it makes people "too picky", and less willing to be patient enough to get to know someone if there isn't an instant attraction, however the way I see it, it is basically just an accelerated version of what is going on in real life anyway. If you're the kind of person who will quickly dismiss someone because they don't fit your mental ideal of the kind of person you want to date or be in a relationship with, then it's likely that the fact you are more able to do this via a dating app doesn't mean that this tendency will be entirely absent otherwise... just that, perhaps, it will take longer to develop. On the other hand if you are a person who is a little more patient and willing to give people the benefit of the doubt, then the accelerated pace of online/app-initiated dating will probably still force you to be a little more selective, both because of the increased availability of potential partners and because statistically you are more likely to have the decision made for you earlier on (as I think human beings in general lean towards the slightly impatiently minded group). In either situation the net result is just less wasted time for everyone involved which can only be a good thing.
I was speaking to a friend about this today and I thought they made a pretty good point. If for the average person there is maybe 1 in 100000 people or something like that with whom there is both a mutual sexual attraction, AND with whom you can actually get on with very well for a very long time, then if you ever want to meet this person playing the numbers game is basically a necessity, and the abundance of choice in this Age of Information should (perhaps optimistically, but, I think, conceivably) lead to a higher proportion of people meeting someone who is actually right for them, and not just "settling" because of lack of choice or fear of being alone.
Honestly I can't at the moment think of a situation where more choice is ever a bad thing. Choice is a symptom of an abundance of opportunity, and this applies to romantic relationships just as much as it applies to anything else, or any path that you choose to take, in life.
