Illustrator-turned-first-time application developer, looking for a point of departure

For nine years, I drew illustrations for kids’ books, usually from small publishers, until I taught myself SwiftUI last winter. My first app is called Crayon Log and it allows parents to take photos of their kid’s doodles and categorize them per month. The number of users I have is 41, out of which 30 are my family members.

I am here because I never launched an application with a dedicated landing page, changelog, and pricing plan. Design I can manage but explaining why one would need to pay for that is another story.

I would like to see how other makers with no technical background start their first launch. Did you have a mentor here or you just watched how others launched? Do you know any threads that a beginner should start with?
