FYI: I don't have any experience in selling mobile apps, just trying to provide a fresh set of eyes here Right off the bat, your target audience is people who play party games with friends or family. But from the looks of it, you're marketing the app only on developer-centric places (SwiftUI Discord/Instagram, HN, etc), and the only marketing you're sharing related to the app is about the challenge. While there is some overlap with these two audiences, they're still very different and you should keep that in consideration. You even mention you tried cold emails - you're not selling a SaaS here, you're selling a mobile party game You also never actually share what gameplay looks like, you just share that you're getting 0 sales, so I think people will understandably be hesitant about buying the app. Consider selling the idea of the app rather than selling the challenge in your marketing. I've spent like 5 entire minutes looking into this app and I still have no clear idea of what the game actually is, and most people are gonna spend no more than 5 seconds if it's a YouTube short. Why rule out ads? It's a good way to get in front of your target audience
