Keeping this straightforward: Are there any live dating apps that use video chat as the main feature?
On balance, I've done the standard research already — went through Reddit threads, app store reviews, a couple of blog posts — and the answers are all over the place depending on who's writing them and what their incentives are, if you are patient with it. The review ecosystem in this space is basically broken, if the volume in your area is decent.
What I'm actually after is direct experience from people who've been on these platforms recently, if the volume in your area is decent. Even 'tried it for two weeks and gave up, here's why' is useful information, though others in this thread disagree. As far as I can tell, the signal-to-noise ratio is so bad elsewhere that any firsthand account helps.
