Custom web and mobile app development for Adelaide businesses

A simple web app with a well defined scope starts at $3,500 AUD. Native iOS or Android mobile builds and projects with R and D depth, hardware integration, or heavy AI infrastructure are quoted case by case after a discovery call, typically starting in the high four figures and scaling into the twenty thousand range and beyond depending on platform mix, integration depth, and engineering scope. We publish the floor honestly because the Australian app development market has a transparency problem and we are not interested in adding to it.

Most small businesses should start with a web app. It is cheaper to build, faster to ship, easier to iterate on, and works across every device with a browser. The question to ask is whether your customers or your team genuinely need the device features of a mobile app. Offline access, GPS, push notifications, the camera, contacts, or App Store presence. If none of those are essential, a responsive web app usually outperforms a mobile app on cost, speed to market, and maintenance overhead. We will tell you honestly on the discovery call.

Native iOS means written in Swift specifically for Apple devices. Native Android means written in Kotlin specifically for Android devices. Cross platform means one codebase that targets both, typically through React Native or Flutter. Native is the better choice when the app needs deep device integration, top tier performance, or platform specific UI patterns. Cross platform is the better choice when the app is content heavy, the budget is tight, and time to market matters more than squeezing every frame of performance. We pick based on the brief, not the trend.

A simple web app with a clean scope ships in four to six weeks. A more involved web app with custom integrations, auth flows, and a back end runs eight to twelve weeks. Cross platform mobile builds typically run eight to sixteen weeks. Native iOS or Android builds, or apps with heavy R and D, run on their own timeline, scoped during discovery. The variable that drives most of the timeline is decision speed on the client side. Apps with one clear decision maker ship fast. Apps with a committee of stakeholders take longer.

Yes, and we are built for it. Most modern AI integration in business apps falls into a small number of practical patterns. Document generation from voice notes or rough text. Diagnostic agents that read structured data and suggest the next action. Customer triage that routes enquiries by intent. Internal knowledge retrieval that turns institutional memory into queryable answers. We integrate Anthropic Claude as the default reasoning layer because reasoning quality matters for business decisions. We also work with OpenAI, Google Gemini, and other models where they are a better fit for a specific task.

Depends on the build. For most current applications, data sits in PostgreSQL on Supabase, Vercel Postgres, or AWS RDS, all of which can be configured to host inside Australian regions for data sovereignty. AI inference for now usually runs through Anthropic, OpenAI, or Google APIs under their published data handling terms, which means inputs and outputs cross international borders. For builds where that is not acceptable, we design data handling around it from day one. Our long term roadmap is sovereign Australian AI compute, so client data and inference stay inside Australian jurisdiction.

Yes, optional. Apps need maintenance in a way websites do not. Operating system updates from Apple and Google break things on a predictable cadence. Library and dependency updates need review. Security patches need shipping. New features get prioritised against real usage data. Some clients run that internally with their own team. Others stay on a light retainer for ongoing development. Month to month. No lock in. The first month after launch is usually included in the build to cover the inevitable post launch tuning.

No code is excellent for fast prototypes, internal tools with a short shelf life, and proof of concept work. It runs into limits when you need real performance, complex business logic, deep integration with other systems, fine grained security control, or App Store grade mobile UX. Most no code builds also depend on a vendor staying alive and not changing pricing or breaking the app with a platform update. A custom build costs more upfront. Across a three to five year horizon it usually costs less, runs faster, integrates better, and never gets held hostage by a SaaS vendor changing their terms. If your app is the digital product or the operational backbone, custom is the right answer. If it is a quick internal experiment, no code is. We will tell you honestly which one fits.
