Side-by-Side Comparison
iOS First wins 6 categories — Android First wins 2 categories
iOS first for most US startups
If you're building for US, UK, or Australian markets and your goal is revenue validation, start with iOS. iPhone users spend more, the device ecosystem is easier to develop for, and you'll get better quality signal faster. Build Android second once you've validated product-market fit. The exception: if your audience is genuinely global or you have data showing Android dominance in your user base, flip it. With React Native, building both simultaneously is affordable if budget allows.
