iOS vs Android — Which Platform Should You Build For First?

One of the most common decisions early-stage app founders have to make is which platform to launch on first. Here is how to think about it properly.

Why this decision matters

Building for both iOS and Android simultaneously is possible but adds cost and complexity. For most early-stage products, starting with one platform and expanding to the other after validating the product is the smarter approach — both financially and strategically.

The question is which one to start with.

The case for starting with iOS

In Australia, iPhone market share sits significantly above the global average. In urban markets and among higher-income demographics — which describe a disproportionate share of early adopters for most new apps — iPhone penetration is even higher.

iOS users also have a well-documented tendency to spend more on apps and subscriptions. If your business model involves in-app purchases, subscriptions, or premium features, the revenue per user on iOS is typically higher.

For most Australian consumer apps, starting with iOS is the right call.

The case for starting with Android

Android dominates globally in terms of sheer device numbers. If your product is targeting markets outside Australia — particularly Southeast Asia, South Asia, or Africa — Android may be where your audience actually is.

Certain categories also skew Android. Utility tools, outdoor and adventure apps, and technical products tend to have stronger Android audiences than consumer lifestyle apps.

The case for building both simultaneously

If budget allows and your audience is genuinely split across both platforms, building both at the start means you are not artificially limiting your potential user base from day one. It also means a single, unified development process rather than two sequential launches.

For products where the launch moment matters — where being on both platforms simultaneously creates a stronger market signal — the additional investment can be worth it.

What we recommend

For most Australian app founders, our recommendation is iOS first if budget is constrained, both platforms simultaneously if budget allows. The decision should be driven by where your specific target users actually are — not by assumptions about which platform is more popular globally.

The answer is different for every product. What matters is that the decision is deliberate, not arbitrary.
