If you're looking to develop another dating app perhaps look for ways to address the problems with existing ones. Here are a few examples: Horrible male to female ratio. Men swipe at everything, women are incredibly picky. F*boys. Female safety fears. Catfishing. Scams. Superficial decision making in matching. Ghosting. Lack of reputation building and tracking in the app. Crappy profiles. Old outdated pictures. Lack of actually wanting to meet.
My humble suggestion: Pivot and come up with something unique that makes online dating a notch better than it currently is.
