I still use the sites in question occasionally, mostly out of habit at this point.
The part nobody mentions about the sites in question is whether anyone replied inside the first week.
What decides the sites in question for most people is how many competing apps are active near you, not the app itself.
Whether the sites in question works comes down to how wide you set the radius more than anything the marketing mentions.
What mattered most with the sites in question in the end was how aggressively it pushed an upgrade prompt.
With the sites in question the thing that decided it for me was whether the radius setting actually worked.
One warning about the sites in question: moving to an external messaging app early is a common scam setup.
That covers what I know about the sites in question, at least.
