I've thought about making a new dating app. The existing apps suck for 2 reasons: in most markets men are at a significant disadvantage because of how men and women differ in the way they approach dating (and there's also a significantly unfair male:female ratio in many markets). Additionally, none of them are really designed to get people off the app, but rather they're built to increase engagement and keep people on the app.

One idea I've had is to disallow conversation in the app, and instead focus on making date plans if there's a match. Another idea is to introduce a payment aspect to make spamming economically unviable, except that the payment goes to the recipient instead of the platform. Some apps have tried things like this, but they kind of suck because it's not real money so it's not useful.
