Use this when you're building in-app upgrade screens, feature gates, or those modals that appear when users hit their free tier limits. It covers timing (show after the aha moment, not during onboarding), copywriting patterns for different trigger types (usage limits vs trial expiration vs feature locks), and the actual UI components that work. The emphasis on "value before ask" and respecting the dismiss action is solid advice that'll save you from annoying users into churning. Includes specific templates for different paywall types and clear guidance on what to A/B test. Distinct from public pricing pages, this is all about those in-product moments where someone's already using your app and deciding whether to pay.
