iOS vs Android: Which Platform Should You Build First?
If you have a limited budget, you often can't build for both platforms simultaneously. This guide explains the real factors that should drive the iOS vs Android decision — based on your target market, monetisation model, and business goals.
Market Share: The Misleading Metric
Android has the largest global market share — roughly 72% of smartphones worldwide. iOS has around 28%. On this metric alone, you'd always build Android first. But market share is the wrong metric for most app businesses.
The more important metrics are:
- → Revenue per user: iOS users spend significantly more on apps and in-app purchases on average. App Store revenue consistently outpaces Google Play despite lower device market share.
- → Your target geography: iOS dominates in the US, UK, Australia, Japan, and Western Europe. Android dominates in India, South-East Asia, Latin America, Africa, and Eastern Europe.
- → Your target demographic: Higher-income demographics and professional users skew iOS. Android has broader reach across age groups and income levels.
If Revenue Is Your Priority: iOS First
Consumer apps that monetise through subscriptions, paid downloads, or in-app purchases typically generate more revenue per user on iOS. If you're building a subscription product for a US or UK audience, iOS is the higher-revenue platform.
iOS users are also more likely to pay for apps upfront. The "freemium with paid tiers" model converts better on iOS than Android for most categories.
If Audience Reach Is the Priority: Android First (in some markets)
If your target market is India, South-East Asia, Latin America, or Africa, Android is the primary platform. In these markets iOS has single-digit to low-double-digit market share — building iOS first would reach a small fraction of your potential users.
Enterprise and B2B apps are an exception — corporate-issued devices often skew iOS even in Android-dominant markets.
Development Differences
iOS Development
- •Requires a Mac (Xcode is macOS-only)
- •Smaller number of device models to test — easier QA
- •App Store review is thorough but predictable
- •SwiftUI provides a modern, fast development experience
- •Stricter privacy and data handling requirements
Android Development
- •Develop on any OS (Windows, Linux, macOS)
- •Massive device fragmentation — more QA effort required
- •Google Play review is faster but policies evolve frequently
- •Jetpack Compose is excellent but ecosystem has more legacy patterns
- •Sideloading and open distribution options
The Both-Platforms Option: Cross-Platform Development
If you need both iOS and Android but can't afford to build two separate native apps, cross-platform development (React Native or Flutter) lets you target both platforms simultaneously from a single codebase — at roughly 60–70% of the cost of two separate native apps.
React Native vs Flutter — which framework should you choose? →Summary: Which Should You Choose?
Build iOS first if:
- ✓Targeting US, UK, Australia, or Western Europe
- ✓Subscription or paid app monetisation
- ✓Higher-income or professional demographic
- ✓Apple ecosystem integrations matter
Build Android first if:
- ✓Targeting India, SE Asia, Latin America, Africa
- ✓Ad-supported or free monetisation model
- ✓Maximum reach is the priority
- ✓Budget or tooling prohibits Mac development
Build both if:
- ✓Budget allows cross-platform development
- ✓Time-to-market requires simultaneous launch
- ✓Global audience across multiple regions
- ✓React Native or Flutter is viable for the app
