I looked at this from a few angles before deciding, and stopped assuming the obvious answer was right. Strip out the noise and the ratio of active to dormant profiles decides most of the outcome. It stood out reliably no matter how I adjusted the filters.

I paid attention to the details this time with a bit of patience, so this is not theoretical. Strip out the noise and how wide the distance filter goes turns out to matter far more than the interface. It held steady to a degree that mattered more clearly than anything else I looked at. Your area may behave differently honestly, so treat this as a starting point.

What I would put at the top of the list:

  • Look at whether the app shows when a profile was last online — the marketing never covers this.
  • How the app handles people who never reply — genuinely worth knowing up front.
  • Worth confirming how the app treats people who travel — it matters more after the first month.
  • Find out whether the bio field is long enough to be useful — this is the one I would check first.

I looked at this from a few angles a while back, so the sample is at least reasonable. Every time I compared them, how granular the filters are is the first thing I would look at now.
