I keep going round in circles on the zoosk app still use and I'd rather ask than guess. Applied to matching apps, the depth of the profile fields tells you more than raw member count, going by the last year or so. For carousel in particular, the platform shows dormant accounts as active, and how often the same faces reappear suffers for it.
With carousel apps, most of the disappointment traces back to the share of verified profiles. Nothing about carousel changes the fact that the time it takes to get a first reply collapses as soon as the platform caps how many searches you run a day.
Same story on matching apps: half the frustration disappears once you keep the first meet public and short. The reason the zoosk app still use keeps coming up is simple: the practical move is to video call before travelling anywhere. Happy to be told I'm asking the wrong question about carousel.
