Hey Eric. I build ASOScan, an app store optimization tool for iOS and Android, so fair warning I'm biased. Your daughter's right that social helps, especially for a launch bump, but for paid games with no ads the channel that keeps paying off is App Store search itself. People search the store and buy what shows up, so a lot of it comes down to making sure your games actually show up. The main lever is your metadata: title, subtitle, and the keyword field. You want the terms players would actually type for your kind of game, ideally ones with real search volume the big studios aren't already sitting on, then you watch where you rank and adjust. It's worth keeping an eye on your ratings and what similar games are doing too, since both feed into how you show up. Happy to look at your three specific games and tell you what I'd change.

I build ASOScan so I'm biased, but this is a known App Store search behavior rather than something wrong with your listing. Since iOS 14 the store runs its own spell-correction, and when an app name is close to a common word (Coriyo vs correo) it redirects the query to the common one. The place to actually push on this is Feedback Assistant (choose Developer Tools & Resources, then App Store Connect). Apple's search team is the only side that can adjust the correction for a brand term. It can be slow, some developers have been at it for months, but it's the channel that gets it changed. In the meantime, the workaround people use is getting users to search "Coriyo app" instead of just Coriyo, since the two-word version usually slips past the autocorrect, or tapping the small "Search for Coriyo" link that appears under the corrected results. You're not the only one. A few others have run into the same thing. It's on Apple's side, not yours.
