The simple, cost-effective tech stack powering a $100K/month app: Expo, Superwall, Adaptee, and a singular MMP. Michael didn’t overcomplicate things - Expo lets him launch to iOS and Android, Superwall handles paywalls, Adaptee speeds up advanced payouts (since Apple’s payout cycles are brutally long), and he tracks installs with one affordable MMP for $0.03 each. Proof that scaling to $100K MRR doesn’t require a massive team or a fancy setup. Simplicity always wins.
