iOS vs Android development — which platform to target first

When building a mobile app, one of the first decisions is whether to target iOS, Android, or both. Each platform has different users, revenue characteristics, development tools, and market dynamics.

This lesson compares iOS and Android development from a practical and business perspective to help you make the right choice for your first app.

Android Development: Market share and user demographics

Android holds roughly 72% global market share, while iOS holds about 27%. But the numbers vary dramatically by region and income:

• US, UK, Japan, Australia — iOS majority (50-65%)
• India, Africa, Southeast Asia, Latin America — Android majority (85-95%)
• Europe — roughly even (45-55% Android)
• iOS users spend 2-3x more on apps and in-app purchases
• Android offers larger total reach; iOS offers higher revenue per user

Development differences in iOS vs Android

Each platform has its own language, tools, and ecosystem:

• iOS: Swift language, Xcode IDE, requires a Mac, strict App Store review, annual $99 developer account
• Android: Kotlin language, Android Studio IDE, works on any OS, more relaxed Play Store review, one-time $25 developer account
• Design: iOS follows Human Interface Guidelines; Android follows Material Design
• Fragmentation: iOS has few device sizes; Android has thousands of screen sizes and OS versions

Which platform to build for first

Your choice depends on your goal:

• Building a consumer app for profit → start with iOS (higher revenue per user, faster App Store review)
• Building for the widest possible audience → start with Android (72% global share)
• Building for a specific market → check that market's platform split first
• Building a portfolio/learning project → choose whichever platform you have a device for
• Want to reach both → use React Native or Flutter from the start

When evaluating android development, start with the fundamentals: what problem it solves, who it serves, and how it compares to the alternatives buyers consider first.

Start with the fundamentals. Define who you are serving, the single outcome you want, and the budget you are comfortable committing before you compare any options.

A practical rule is to favour clarity over cleverness. The choice that is easiest to understand, spell, remember and act on tends to win over the long run.

Context changes the answer. What is optimal for a fast-moving startup is rarely optimal for an established brand, so weigh your own stage, market and ambitions.

Avoid the common mistakes: rushing the decision, copying competitors blindly, and ignoring the total cost of ownership beyond the very first year of use.

Think in terms of trade-offs rather than a single perfect answer. Every option trades memorability, cost, reach and flexibility in a slightly different mix.

Document your reasoning. Writing down why you chose one path makes it far easier to revisit the decision later and to explain it to partners and investors.

Test with real people. A quick check with a handful of your actual customers will surface problems that no amount of internal debate ever reveals.

Plan for growth. The option that fits today should still make sense when your audience, catalogue or team is several times larger than it is right now.

Finally, revisit the decision periodically. Markets, tools and best practices move quickly, and a choice that was ideal last year may deserve a fresh look today.

Frequently asked questions

Do I need a Mac for iOS development?

For native iOS development with Swift and Xcode, yes — a Mac is required. For cross-platform development with React Native or Flutter, you can develop on any OS, but you still need a Mac (or a cloud Mac service) to build the final iOS app.

Which platform pays developers more?

iOS developers earn slightly more on average ($125K vs $115K in the US), but the difference is narrowing. Both platforms have strong job markets. Cross-platform developers (React Native/Flutter) are increasingly in demand.
