I created this while preparing my first app, PhotoFit, with help from AI tools. The case in the book is documented through October 17, 2026. It covers preparation such as country settings, tester lists and CSV files; it does not demonstrate a completed closed test or an approved launch.
The package includes a 113-page PDF/HTML guide, 8 task cards, an 8 min 44 sec lesson with AI-generated English narration, a CSV checker and 5 templates. Korean and bilingual editions are also available.
