Why iOS

If you're building mobile apps to make money, you need to start with iOS. Not both platforms. Not Android first. iOS.

This isn't platform tribalism. It's business math.

The Revenue Reality

Apple users spend more money on apps. Period. The App Store generates roughly twice the revenue of Google Play, despite having fewer total users. For independent developers, this gap is even wider:

• Higher willingness to pay — iOS users expect quality and pay for it
• Better subscription conversion — StoreKit and native payment flows have less friction
• Lower refund rates — Android's instant refund policy kills subscription revenue

When you're a solo developer, every dollar matters. Building for the platform where users actually pay isn't a preference — it's a survival strategy.

Ecosystem Quality

Apple's ecosystem is genuinely better for solo developers:

• Xcode — One IDE for everything. Interface Builder, Instruments, Simulator, all integrated
• TestFlight — The gold standard for beta testing. Nothing on Android comes close
• StoreKit 2 — Modern subscription APIs that actually make sense
• SwiftUI — Declarative UI that AI tools understand exceptionally well
• App Review — Yes, it's strict. That strictness keeps quality high and scammers out

The Focus Advantage

Building for one platform means you ship 2x faster. Every hour you spend on cross-platform compatibility is an hour you could spend building your next app.

The math is simple:

• 1 platform = 1 set of APIs, 1 build system, 1 set of guidelines, 1 review process
• 2 platforms = 2x everything, but rarely 2x revenue

When you're building a portfolio of 30+ apps, that efficiency compounds dramatically. A cross-platform approach at scale isn't twice the work — it's an exponential drag on your velocity.

When to Add Android

Android isn't off the table forever. But it comes after you've validated on iOS:

1. Prove the concept on iOS — Does the app make money?
2. Build your shared framework — Invest in your toolkit
3. Add Flutter as a second stack — We cover this in Part V

The key insight: iOS-first doesn't mean iOS-only. It means iOS first.

What This Means for You

If you're following this course, you're building iOS apps. Your toolkit is:

• SwiftUI for native iOS apps
• Xcode + XcodeGen for project management
• StoreKit 2 / RevenueCat for monetization
• Claude Code for AI-assisted development

Everything in this course is built around this stack. When we introduce Flutter in Module 15, it's as a complement — not a replacement.
