What can make online dating better?

For the majority of people online dating is horrible. What do you think that can make it better on both sides? I used to have a dating app 10 years ago but needed to start actually making money so I stated a different business. But it seems like there has to be a way to make these apps better. Tinder used to have a wall where people can post on and engage with each other which was great but then the online sex workers took it over so they got rid of it. What do you think is a major issue that can be fixed?
