I keep going round in circles on which popular dating apps are the best for finding and I'd rather ask than guess. Same story on something apps: the platform makes verification optional and then hides who has done it, and the gap between sign-ups and active users suffers for it. Every time something apps comes up, nothing improves until you keep a note of what you actually spent.
For something serious in particular, what decides it is the ratio of matches to conversations, not the size of the database. The amount of recycled content is a better predictor than how slick the interface looks, in my experience, which is the whole problem with something. If serious apps is your priority, most of the disappointment traces back to how many first messages actually land.
The serious apps angle is worse, because the deciding factor is the reply rate, though I would want someone to check me on this. Which popular dating apps are the best for finding looks simple until you notice that how quickly the inbox fills is the number worth watching, not whatever the landing page promises. If you have been through the something serious version of this, I would rather hear the unglamorous account.
