Wemark Tech designs, builds and launches custom iOS and Android apps for Adelaide businesses and clients across Australia. Whether you need a customer booking app, a staff tool, a marketplace or an internal system, we start with the job the app has to do, then choose the native or cross-platform approach that fits your users, budget and timeline. We also build the website, backend and integrations around it, so the app works as part of your business instead of on its own.
Many apps disappoint because nobody checked that an app was the right answer in the first place. Before we write a line of code, we work out whether your project needs an app, a web app or a stronger website, and we tell you plainly which one.
If a responsive website or web app would do the job for less, we will say so before you commit to development. We build websites and software in-house, so the advice is not tied to selling you an app.
Short answer: choose cross-platform when you need iOS and Android quickly with a shared feature set, native when performance or deep device features define the product, and a web app when users should not have to install anything. We recommend one approach during discovery and explain the trade-offs for your budget and growth plans.
Native app development means building a separate app for each platform with its own tools. It suits products that depend on fast, responsive performance, offline use, camera, GPS, Bluetooth or push notifications, and consumer apps where design and usability are the product. The trade-off is two codebases, which usually means a higher build and maintenance cost.
One codebase powers both iOS and Android, which usually shortens delivery and lowers cost. It suits booking, ordering, marketplace and internal operations apps with a defined feature set, and businesses that want to launch on both platforms together. The trade-off is that very demanding performance or newer platform-specific features can need extra native work.
When users need a tool rather than an icon on their home screen, a responsive web app or a better website can deliver the result faster and with no app store approval. We build those too: see Website Development.
Every engagement is scoped to your product, but the work falls into these six areas.
We define your goals, users, core features and technical requirements, then agree a prioritised first release so the budget goes into what matters most.
User flows, wireframes, interactive prototypes and polished interfaces, so you can see and test how the app works before development starts.
Native iPhone, iPad and Android apps, or one cross-platform build for both, including customer-facing apps for booking, ordering, loyalty and membership, and internal tools, workflows and dashboards.
Secure databases, user accounts, admin systems and third-party integrations, so the app connects to your website, CRM, payment systems and other business tools.
Apple App Store and Google Play submission support. Helping people find and download the app afterwards is a separate service: App Store Optimisation.
Updates, monitoring, security maintenance, bug fixes and new features after your app goes live.
For a small business, an app should reduce admin, make life easier for customers, or open a better way to sell and serve, and it should do that in version one. We help you define a focused first release that solves one clear problem, launch it to real users, then expand it based on what they actually do.
That keeps the first budget in check and gives you real usage data before you invest in the next set of features. If you are not sure whether an app, a web app or an improved website is the right investment, we will help you assess the options before committing to development.
As a guide, a lean MVP often costs around A$40,000 to A$90,000 and takes around 6 to 10 weeks, while a mid-market app costs more and takes longer. The right figure depends on scope, platforms, integrations and compliance.
Around 6 to 10 weeks. A focused first version with limited features, a simple backend, basic analytics and minimal integrations.
Around 10 to 18 weeks, depending on scope, integrations, testing and team capacity.
Scoped individually. Integrations, AI, compliance and infrastructure drive the cost and the timeline.
These are market guides for Australian projects, not a quote. A common rule of thumb is to budget around 15 to 20 per cent of the build cost each year for maintenance and updates. We quote against a written scope, so you know what is included before work starts. If your budget is smaller, we can look at a more focused first release, or whether a web app or website would serve you better.
We learn your business, customers and competitors, then define the problem, core features, user journeys and success measures. You receive a written scope and a prioritised feature list.
We map the app structure, wireframe the screens and prototype the main flows, so you can test how it works before development starts.
We build in planned stages with regular progress updates, then test across devices, screen sizes and real-world use before anything goes live.
We handle Apple App Store and Google Play submission, then monitor performance, fix issues and release updates as your users show what they need.
We're based in Blair Athol, Adelaide, and work with businesses across Australia. Because we also build websites and software in-house, we can deliver the app, the backend, the website and the integrations as one project, instead of leaving you with a list of work for another supplier.
We build our own products too. LeadGlue, our lead management platform for Australian real estate agencies, includes an iPhone app on the Apple App Store, where agents add notes by dictation between appointments. See more of what we have built on Our Work.
Once the app is live, we can help people find it with App Store Optimisation, and connect it to your business with AI automations.
It depends on scope: the number of features, design depth, platforms, integrations and backend. As a guide, a lean MVP with limited features, a simple backend, basic analytics and minimal integrations may cost around A$40,000–A$90,000, while a mid-market app can cost A$90,000–A$220,000. Complex enterprise products can exceed A$220,000 depending on integrations, AI, compliance and infrastructure. These are market guides, not a quote. We quote against a written scope, so you know what is included before work starts.
A lean MVP may take around 6 to 10 weeks, while a mid-market app can take 10 to 18 weeks, depending on scope, integrations, testing and team capacity. You get a realistic timeline for your project at the end of discovery.
Yes. We build for both platforms, using native development or a cross-platform approach, whichever suits your requirements.
Choose native when performance, advanced device features or a premium experience are central. Choose cross-platform when you need iOS and Android versions with a shared feature set and a faster, more economical launch. We recommend the best fit during planning.
Yes. We work with small businesses and startups in Adelaide and across Australia, and we help you define a practical first version so you can launch without overbuilding.
Yes. We can audit an existing app, fix issues, improve the design, add features, rebuild outdated technology or migrate it to a more scalable platform.
Yes. We offer ongoing support, monitoring, updates, security maintenance and feature development after your app goes live.
Yes, as a separate service. App Store Optimisation improves your store listing and can include paid install campaigns. Nobody can guarantee rankings or download numbers, and we do not.
No. We're based in Blair Athol in Adelaide and work with businesses across Australia. We meet in person in Adelaide and online everywhere else.
