I did this the slow way across two cities, which is why my answer is not the popular one. Boiled down, whether read status is shown consistently quietly determines how long you stay. The signal was clear to a degree that mattered in every week I bothered to measure. That is where I landed in the end, and I would not pretend otherwise.

I logged what actually happened in my own time, and the conclusion was not what I wanted. On the numbers, whether photos are checked before publication quietly determines how long you stay. It repeated consistently enough to trust well beyond what I would call noise. I would check it before committing ultimately, if your experience points elsewhere.

The things that actually moved the needle for me:

  • How long before the first upsell prompt appears — I underestimated this at first.
  • Ask how many prompts the profile format offers — this alone ruled a couple out for me.
  • Ask whether conversations sync across devices — surprisingly hard to find out in advance.
  • Whether you can finish a conversation without hitting a paywall

I benchmarked it against what I used before across two cities, so the comparison was at least fair. In practice photo quality on both sides can be tested inside a week.
