How Much Does a Mobile App Cost in Australia?
App quotes range from a few thousand dollars to several hundred thousand, and the gap is rarely about quality. Here's what actually drives the price, realistic cost bands, and the ongoing costs most quotes leave out.
"How much does an app cost?" is the question we're asked most often, and the honest answer — somewhere between $30,000 and $400,000 — is so wide it's almost useless on its own. The range isn't evasiveness. It's that "an app" describes everything from a five-screen booking tool to a platform with payments, real-time sync, and an admin system behind it.
What's more useful is understanding the levers that move the number, so you can judge whether a quote is reasonable and decide which parts are worth paying for.
What actually drives the cost
Almost all of the variance comes down to six things.
1. Number of screens and flows. This is the crudest predictor, and still one of the best. Every screen needs design, build, state handling, error cases, and testing. A 10-screen app isn't twice the work of a 5-screen app — it's usually a bit more, because the interactions between screens multiply.
2. Whether you need a backend. An app that only runs on the phone is dramatically cheaper than one that syncs data between users. The moment you need accounts, shared data, or an admin view, you're building a server, a database, and an API as well as the app itself. Many people quote "an app" and mean "an app plus a platform".
3. Integrations. Payments, maps, calendars, identity verification, accounting systems, existing internal databases — each one adds work, and each one adds failure modes you have to handle gracefully.
4. Design expectations. A clean, conventional interface built on the platform's standard components is efficient. A distinctive, heavily branded experience with custom animation is a different exercise entirely, and it shows up in the quote.
5. Compliance and data sensitivity. Health, financial, and children's data all carry obligations that change how you build, store, and log things. That work is real, and skipping it is not a saving — it's a deferred liability.
6. Who builds it. A senior local team, an offshore agency, and a freelancer will quote very differently. Cheaper is sometimes fine. It's rarely fine when the app is central to how you make money.
Realistic cost bands
Treat these as indicative Australian market ranges for a competently built app, not a quote:
| Type of app | Typical range (AUD) | Rough timeline |
|---|---|---|
| Simple, no backend (calculator, guide, single-purpose tool) | $30k – $60k | 6 – 10 weeks |
| Standard app with accounts and a backend (booking, marketplace-lite, member app) | $70k – $150k | 3 – 5 months |
| Complex platform (real-time features, payments, multiple user types, admin portal) | $150k – $400k+ | 6 – 12 months |
If a quote sits far below the relevant band, that's not automatically a bargain. Ask what's been excluded — it's usually testing, backend work, or the unglamorous parts like error handling and app store submission.
Native or cross-platform?
This decision is often presented as a technical religious war. In practice it's an economic one.
Cross-platform (React Native, Flutter) means one codebase serving both iOS and Android. For the large majority of business apps this is the right call: you get both platforms for roughly 60–70% of the cost of building each separately, and the result is indistinguishable to users.
Native (Swift for iOS, Kotlin for Android) is worth it when you're leaning hard on platform-specific capabilities — heavy graphics, intensive background processing, deep hardware integration — or when the app is the product and every millisecond of polish counts.
For a booking app, a member portal, a field-service tool, or an internal operations app, cross-platform is almost always the sensible default. We build most client apps this way for exactly that reason.
The costs quotes tend to leave out
The build price is not the total price. Budget for:
- App store accounts. Apple charges USD $99/year; Google is a one-off USD $25.
- Backend hosting. Anywhere from $30/month for something modest to several hundred as you grow.
- Third-party services. Push notifications, SMS, mapping, identity checks and payment processing all meter usage.
- Ongoing maintenance. Budget roughly 15–20% of the build cost per year. This isn't padding — iOS and Android ship breaking changes annually, and an unmaintained app quietly stops working.
- App store review. Rejections happen. Build in time for a round or two of back-and-forth, particularly for anything involving payments or user-generated content.
The maintenance line is the one that surprises people most. An app is not a website you can leave alone for three years. Plan for it up front and it's manageable; ignore it and you'll be quoted a rebuild in two years.
How to spend less without regretting it
There are good ways and bad ways to reduce an app budget.
Sensible savings:
- Ship one platform first. If your users skew heavily iOS or Android, launch there, learn, then expand.
- Cut scope, not quality. Fewer features built properly beats many features built carelessly. Our guide to scoping an MVP goes deeper on this.
- Use proven components for solved problems — authentication, payments, push — rather than building them from scratch.
- Start with a web app if your users don't genuinely need to be on a phone. A responsive web app is cheaper, has no app store gatekeeping, and updates instantly.
False economies:
- Skipping testing. You'll pay for it in support and reviews.
- Skipping analytics. You'll be guessing about what to build next.
- Choosing purely on price. The cheapest quote frequently becomes the most expensive project once you factor in rework.
What to ask before you sign
A good quote should survive these questions:
- What exactly is included — design, backend, admin panel, testing, store submission?
- Who owns the code and the accounts? The answer must be you. If it isn't, walk away.
- What happens after launch, and what does support cost?
- How will we see progress? You should be using something real within weeks, not waiting months for a reveal.
- What's explicitly out of scope? The exclusions tell you more than the inclusions.
A quote that's vague about scope isn't cheaper. It's just deferring the conversation about what you're actually paying for.
If two quotes differ by a factor of three, they're almost certainly describing different projects. Get both to itemise, and compare like for like.
