How Much Does an App Cost in Australia? 2026 Guide

The factors that decide what an iPhone and Android app costs to build in Australia, and how to keep the first version affordable.

The cost of an app in Australia depends on how many screens and features it has, whether it needs accounts, payments and maps, what systems it connects to, and whether you need iPhone, Android or both. A focused first version costs far less than a full platform. This guide explains what drives the price, the costs people forget, and how to get a quote you can rely on. For our approach, see mobile app development.

Why there is no single price

Asking what an app costs is like asking what a building costs. A garden shed and an office tower are both buildings. An app with five screens and no login is a small project. An app with customer accounts, payments, live maps, an admin system and integrations is a large one. The useful question is: what is the smallest app that solves the problem?

The six things that drive app cost

A smartphone surrounded by icons for screens, user types, security, payments, a back-end cloud and integrations, the main things that drive app cost.
Cost follows the number of screens, user types and connected systems, not the idea.

1. Screens and user types

Every screen has to be designed, built and tested. Different user types multiply the work: an app for customers only is simpler than one with customers, staff and managers who each see different things.

2. Accounts and security

Sign-up, login, password reset, roles and data protection are essential when people store personal information. They are invisible when done well and expensive to fix when skipped.

3. Payments

Taking card payments, Apple Pay and Google Pay through a provider such as Stripe adds work for the payment flow, receipts, refunds and GST.

4. Device features

GPS, camera, offline mode, background location and push notifications each need extra development and careful testing on real phones.

5. The back end

Most apps need a server, a database and an admin area behind them. This is often half the project, even though users never see it.

6. Integrations

Connecting to your website, CRM, accounting or booking system saves double entry later, and each connection needs to be built and tested.

Native, cross-platform or web app?

Three options side by side: two separate phones for native apps, one shared build for phone and tablet, and a browser window for a web app.
Native means two codebases, a cross-platform build covers iPhone and Android from one, and a web app stays in the browser.

Building separate native apps for iPhone and Android means two codebases and close to double the work. Cross-platform tools such as React Native let one team ship both from one codebase with native performance, which is why we use React Native and Expo for most projects.

A mobile-friendly web app can be cheaper again when you do not need to be in the app stores or use device features such as background location. It is worth asking whether your idea really needs to be an app.

Costs people forget

  • Apple and Google developer accounts, and time for app review.
  • Hosting, monitoring and backups after launch.
  • Updates each year for new phone operating systems.
  • Support and improvements once real users arrive.
  • Design: good apps are designed before they are built.

How to keep version one affordable

List every feature you want, then mark the ones users need on day one. Build those, launch, and use real feedback to decide the rest. Features you were sure about often turn out not to matter, and that money is better spent on what users ask for.

We built and published the Rostery worker app this way. It started with shifts and clock-in, and features such as trip capture, documents and charts were added as providers asked for them.

How long projects usually take
Website3 to 8 weeks
First version of an app or system6 to 16 weeks
First version of a SaaS product8 to 14 weeks

Our own typical ranges. The scope decides where a project lands.

How to get a reliable quote

A useful quote needs a short scope: who the users are, the main tasks they need to do, and the systems involved. Be wary of a price given without questions. We run a short discovery session, then give a fixed scope and price in AUD before any build starts. Our pricing guide explains how we price.

Questions to ask any app developer

  • Will we own the code and the store accounts?
  • Who handles App Store and Google Play review?
  • What does support cost after launch?
  • Can we see an app you have published?
  • What happens if the scope changes?
