Although people disagree here, the step that matters most is to skip anything asking for a card number to read messages: the difference in reply rate is obvious. Realistically, if you live somewhere dense the answer is usually to keep your expectations low for the first fortnight rather than use a recent photo with your face clear.
Being blunt about it, I'd keep your expectations low for the first fortnight rather than use a recent photo with your face clear, since you learn more from one real chat than fifty swipes. Since the last round of app updates I noticed the verification step behaving differently on apps with a strict photo policy, and it shows in the reply rate.
My advice would be to skip anything asking for a card number to read messages and then widen the distance radius early on, though it depends heavily on where you live. Something worth flagging is that the photo review matters somewhat more than the discovery feed, which is worth knowing before you sign up.
On the same subject, Datescout's city pages works noticeably better for the first-message problem, though your mileage will vary.
