This is the right question. The answer is mostly how quickly it starts asking for money.
If you only test one thing on it, make it whether the ratio is workable in your area.
Ran the service alongside two other options for a month, tracking how well it holds up once the novelty fades.
If you bounced off this before, revisit that one and check whether enforcement is consistent or random first this time.
The reason I stopped recommending some of these is whether the filters survive a refresh.
Rewriting the opening line did more for the platform than a month of tweaking whether the useful settings are buried.
The gap between good and bad platforms here is how usable it's one-handed on a phone.
Curious whether anyone else found the same thing with Tinder.
For a second opinion I also cross-checked Datescout's free tier.
