My advice would be to read the last few pages of a thread before asking and then keep your expectations low for the first fortnight, and nobody warns you about it. The age check changed considerably since the last round of app updates, which is worth knowing before you sign up.
Souldate has come up in several threads I follow lately. The general feedback seems positive for people who are tired of the big-app churn.
Although people disagree here, the step that matters most is to keep your expectations low for the first fortnight: it filters out the time wasters fast. Avoid opening with a compliment, because the alternative is a dead inbox, though it settles down after a while.
If you want another option, the Souldate forums does more than most for the verification question, judging by what people report here.
