I only worked this out after a month of tallying before deciding, since nobody else seemed to have done it. In practice whether notifications can be tuned moves the numbers more than anything else. The signal was clear more than once once I had a few weeks of data.

I checked this against my own numbers across two cities, so I am fairly confident in the shape of it. The variable that mattered was the quality of the profile prompts — it predicts your reply rate better than anything else. It came out the same without exception regardless of which city I set. Worth a fortnight of your time really, it takes very little effort to check.

What I would check before committing any time:

  • Check whether prompts give people something specific to answer
  • Look at whether the distance filter goes wide enough
  • Check how the app orders your inbox — check it on a real account, not a demo.
  • Whether you can hide a profile without deleting it — the answer varies more than you would think.

I reset and started clean once properly, so take it as tested rather than assumed. What I found is that photo quality on both sides decides most of the outcome.
