Paywall Generator
Generate a complete StoreKit 2 subscription paywall with modern SwiftUI views, subscription status tracking, and proper purchase handling.
When This Skill Activates
Use this skill when the user:
Asks to "add subscriptions" or "add paywall"
Mentions "in-app purchases" or "IAP"
Wants "StoreKit 2" implementation
Asks about "subscription management"
Mentions "premium features" or "pro version"
Paywall Design Principles (Apple's Data)
Keep sign-up to 3-4 taps. Per Apple's Tech Talk: 61% conversion at 3 taps, 48% at 4 — collapsing to 7% at 9 taps.
Make the paywall glanceable — value proposition, price, and renewal/trial terms in one view, no scrolling to find the price.
Show clear renewal and trial terms everywhere you pitch the subscription, not just on the paywall.
Persistent entry point over pop-ups — a tasteful, always-available subscribe button (plus subscribe/manage in Settings). Pop-ups train users to dismiss.
Trigger the offer at moments of interest — when the user taps locked content, not on a timer.
Offer 3-4 duration tiers so users self-select their commitment level.
Let users experience value first — free trial (works best for known brands), freemium, or content sampling (e.g., N free articles per month).
