Cross-platform app development for both app stores

Cross-platform app development means building your app once and running it on both iOS and Android, rather than paying for two separate native apps. For most Australian businesses that need to be on both stores, it is the sensible default, because it cuts cost and time without a meaningful drop in quality that users would notice. This page explains the business case behind that, the honest trade-offs, and how to decide whether cross-platform is right for you.

The business case in plain terms

The logic is straightforward. If you build native, you build two apps: one in Swift for iOS and one in Kotlin for Android. That is two codebases to write, two to test, and two to maintain forever. Cross-platform replaces that with a single codebase that produces both apps, which means you build once and maintain once.

The saving is typically 30 to 40 percent on the build, and it keeps paying off after launch, because every future change is made once instead of twice. For a business weighing where to spend a finite budget, that difference is often what makes the project viable, or what frees up money for features that matter more than having two separate codebases. The apps your users download still feel native; the saving sits behind the scenes.

What you are not giving up

The old objection to cross-platform was that it meant visible compromises. That was a fair criticism years ago and is not true now. Modern frameworks compile to genuinely native interfaces, and the resulting apps are smooth, fast and indistinguishable from native to the people using them. Large companies ship cross-platform apps to millions of users without complaint.

What you give up is narrow and specific: the absolute bleeding edge of new platform features on launch day, and the last few percent of performance in the most demanding apps. For a game studio or an app built around heavy real-time processing, those matter. For a booking app, a marketplace, a customer app or an internal tool, they do not, which is why cross-platform suits the large majority of what businesses actually build.

The frameworks behind it

Cross-platform is a category, not a single product, and the two leading tools are Flutter and React Native. They are both mature, widely used and well supported, and either produces excellent apps. The choice between them comes down to your situation rather than a clear winner.

Flutter often gives slightly smoother performance straight away and a very consistent experience across platforms. React Native fits naturally when you already have web or JavaScript developers, because it shares a language and some code with the web. We choose deliberately for each project and explain the reasoning, rather than forcing every app through the same tool because it suits us.

What you can build cross-platform

It is worth being concrete about the range cross-platform covers, because the impression that it is only for simple apps is wrong. We have built marketplaces, booking and scheduling apps, customer loyalty and ordering apps, field tools for staff with offline support, content and media apps, and internal business systems, all cross-platform, all on both stores from one codebase. These are real, capable apps with payments, accounts, maps, notifications and live data, not stripped-down versions.

The features that make up the vast majority of apps, accounts and login, payments, bookings, content, search, messaging, maps and notifications, are all well supported in cross-platform frameworks. When an app does need a specific native capability that the framework does not cover directly, modern cross-platform tools let us drop down to native code for just that piece, so a single unusual requirement does not force the whole app to be native. That flexibility is part of why cross-platform fits so much of what businesses actually build, and why the cases that genuinely require full native are narrower than people assume.

When native is still the answer

We would not be honest if we pretended cross-platform was always right. There are real cases where native earns its higher cost. Apps that need the newest platform capability the day it ships. Apps that demand the highest possible performance, such as games or intensive real-time tools. And apps built almost entirely around heavy device features like advanced camera processing or augmented reality.

If your app is one of those, we will tell you, and point you toward a native build instead. Our native versus cross-platform guide lays out that decision in full. The goal is always the right tool for your app, not the one that happens to be cheapest or easiest to sell.

How we build and what it costs

We build cross-platform apps in two-week sprints with a working demo at the end of each, tested on real iOS and Android devices, then submitted to both stores by us. Most projects land between $30,000 and $120,000, covering both platforms from one build, with the figure moving on features, backend and design.

Whatever you build, you own all the source code and your app store accounts. If you need to be on both iOS and Android and want to spend your budget wisely, tell us what you want to build and we will send a free, fixed-price quote, with an honest recommendation on whether cross-platform or native fits your case. For most businesses the answer is cross-platform, and we will explain exactly why for yours rather than asking you to take it on faith, because the right reasoning matters as much as the right recommendation. And on the rare occasion native genuinely is the better fit, you will hear that from us just as plainly, since the goal is the best outcome for your app rather than the easiest one for us to deliver.
