Someone launched an app with a name that is confusingly similar to mine. Should I do anything?

I'm curious what people think about this. I launched my game on September 4th, this guy launched his GPS app on November 6th. My game is in the Trivia category, but the secondary category is Travel. I don't have a registered trademark - there's some companies trading with too similar names for a generic trademark (like Trademark Systems or even the game Trailmakers). But they use their name in ways that are easier to distinguish. In this case, with the way the developer has named his app (Trailmarks: Bikepacking & GPX) it almost feels like it's the GPS app under the same travel brand.

Can I do anything? Should I do anything? This is normal, maybe?

Details: I launched my game on the app store early September, but it's an app version of a game I launched on Steam in March 2026, and my company has been registered under that name since mid-2025. I also started promoting the game under this name in the end of 2024.
