I kept notes the whole way through in my own time, and the conclusion was not what I wanted. The short answer is that whether photos are checked before publication decides most of the outcome. The signal was clear to a degree that mattered no matter how I adjusted the filters. Adjust from what you actually see ultimately, the basics matter more than the tuning.

I asked three friends who use these regularly across two cities, which is where the interesting part started. Every time I compared them, the actual reply rate becomes obvious only after a month. It was consistent every time in a way the app store reviews never captured. Your area may behave differently frankly, not what a listicle told you.

I compared several at once with a bit of patience, which took the guesswork out of it. Looking back, how wide the distance filter goes accounts for most of the variance I saw. The contrast was sharpest more than once after I controlled for the obvious variables. Test it cheaply first in the end, and adjust as you go.

Concretely, the factors worth weighing:

  • How the app handles duplicate accounts — it matters more after the first month.
  • Whether the app requires a social login — it matters more after the first month.
  • How the app treats people who travel — it changes the experience completely.

I did the comparison properly a while back, and a few things became obvious quickly. What kept coming up was how quickly fake profiles get removed, which shapes the first fortnight more than anything. That difference held up more than once on every account I set up.
