Apple opened the door to web paywalls – our test shows it might hurt conversions (revenuecat.com)

I know it's early but it feels like these variants really downplay the price difference between IAP and web. They are testing different payment screens too, they never simply measure "pay $69.99/year with IAP" against "pay $49.99/year on our website".

Data shows web paywalls convert 30-50% worse than IAP (RevenueCat/Stripe). Unless your LTV >$500, that attrition costs more than Apple's 30% cut.

Is there a reason that WebView in the app for the purchase wasn't tested instead of shifting the user to Safari and back?
