iOS vs Android App Development: Which to Build First?

Every founder building their first mobile app hits this question within the first 10 minutes of scoping: iOS or Android app development? Build one now, one later? Or try to do both simultaneously? The answer matters — it affects your launch budget, your development timeline, your first-year revenue, and which half of the world actually gets to use your app.

ta, the real development differences, and the business logic to make the call confidently — including when the smarter move is to skip the debate entirely and build both platforms at once with Flutter.

Quick Summary: Build iOS first if targeting the US, UK, Australia, or Western Europe — iOS users spend 2× more and generate higher app revenue. Build Android first if targeting India, Southeast Asia, Africa, or Latin America — Android holds 72%+ global market share and 95%+ in emerging markets. Build both with Flutter if your budget is $25K+, you can’t afford to miss half your market, and you want to launch in both stores simultaneously — one codebase, native performance on both.
