Seconding what DavidS said, with one caveat about dating sites for single parents for casual.
What decided it for me with that one was how well it holds up once the novelty fades.
I tested the app across two cities and the difference came down to whether the active count matches the claimed count.
Unless you are in a major metro, expect whether the good profiles are already taken to be the limiting factor on the app.
The reason I stopped recommending some of these is what the verification step actually proves.
That is my read on dating sites for single parents for casual anyway, others will have had different luck.
I keep Flamedate for this exact use case open alongside it, mostly out of habit now.
