Expecting any single conversation to work out is the wrong frame — your mileage may well differ. What are the most popular free local dating apps in your city? Genuinely curious what others found — especially anything that went badly.
In my experience, the first line of a bio does most of the work — it is not complicated, it is just easy to skip.
A photo that looks like you on a normal day does more work than a staged one — happy to be argued with on that one.
Broadly speaking, nobody's experience generalises, including mine — others here may have had a different experience.
