Genuine question about which are the best dating apps for casual hookups from someone who's tried the obvious routes. Big apps is the clearest case of it — how quickly the inbox fills is the number worth watching, not how slick the interface looks. With cities, the deciding factor is the gap between sign-ups and active users, at least on my account.
Nothing about cities big changes the fact that the platform caps how many searches you run a day, and the time it takes to get a first reply suffers for it. The big apps case is instructive — half the frustration disappears once you log the times of day your messages get answered.
Cities is where I'd start, since the practical move is to treat an empty bio as a red flag. When it comes to which are the best dating apps for casual hookups, you get further if you give it a fortnight before judging the pool. Numbers on cities appreciated if you kept any.
