Your paywall is a product feature. What I've seen work on apps that actually hit real MRR:

→ Show the value before the paywall. Let users hit the "aha" moment first, then ask for money → Test the paywall copy and pricing like any other feature. Don't treat it as a one-time decision → Use RevenueCat (or similar) from day 1. Don't build subscription logic from scratch, because refunds, renewals, and restore-purchase edge cases will eat your month → Track trial-to-paid conversion before you track downloads

An app with 1,000 users and a good paywall beats an app with 10,000 users and a bad one.
