The problem with launching any kind of dating app is that you need attractive people on the app to keep customers engaged, but attractive people won't use your app unless there are already other attractive people 'in their league' on it. Classic chicken-and-egg situation that is only exacerbated now that the idea is no longer new and trendy. Being open source and ethical makes it even worse because you can't just make/encourage fake profiles or (intentionally) design the app to be addictive, both of which are tried and true strategies to retaining your user base.
A successful launch would need two things:
1) a slow, steady bring-up where only attractive people are allowed on the site at first and you slowly bring uggos and sickos on board as you gain steam.
2) something besides the stupid swiping model. It's great for getting users addicted but it's also just about the least effective way to find a mate. Honestly you'd be better off with an app that just selects you one match a day based on various parameters. This makes the matching criteria more meaningful and forces people to actually think for more than half a second about the people they see on the app. Plus reduces the anxiety of putting your face on a public forum.
Let's be real though. Anything libre will inevitably have nothing to offer the heterosexuals.
