Roast My App is a paywall and onboarding conversion rate optimization (CRO) consultancy for mobile subscription apps, working as an embedded growth product design partner for B2C app teams. Founded by Muhammad Rahat, a CRO specialist who has torn down 187+ subscription paywalls and writes the "Roast My App Memos" newsletter. Our monthly Paywall & Onboarding CRO Program ships 3+ RICE-prioritized experiments each month, tracking install-to-paid, trial-start rate, trial-to-paid conversion, and D0/D7/D30 ARPU. We focus on paywall design, pricing, packaging, personalization, onboarding funnel design, and core-feature activation, with full-stack implementation in Swift, React Native, RevenueCat, Superwall, Adapty, and Purchasely. We also offer a standalone paywall A/B test and a free CRO audit. Clients typically see 20-40%+ additional subscription revenue without increasing marketing spend.
