Mobile App Development for iOS, Android and the Web

Custom App Development refers to purpose built enterprise software that replaces or augments core business systems, think loan origination platforms, permit management systems, or complex operational tools. Web & Mobile Applications is broader and encompasses customer facing products, internal productivity tools, portals and digital experiences where the focus is equally on user experience quality, front end performance, and omnichannel delivery. In practice, a build often draws from both services. We scope based on what you are building and recommend the right approach for the complexity involved.

The decision depends on four factors: the distribution of your user base across device types, the performance and hardware requirements of the application, the ongoing maintenance capacity of your team, and your go to market timeline. For most enterprise internal tools and B2B products, a responsive web application or a Flutter cross platform app gives you the best return. Native iOS and Android development is warranted when you need deep hardware access (camera, AR, Bluetooth LE) or when App Store distribution to consumers is a primary acquisition channel. You get a specific recommendation with clear trade offs as part of your Discovery Audit.

We define a minimum device support matrix at project start based on your actual user data or the Australian market distribution if you are launching a new product. Performance budgets are set for this baseline device, not the latest flagship hardware. We test on physical Android devices including midrange Samsung and Oppo handsets, and use Chrome DevTools throttling to simulate 4G and 3G conditions during development, not just as a final check. Bundle size is monitored through automated CI checks, and any PR that inflates the bundle beyond a threshold requires justification.

Integration is a standard component of every application we build. We integrate with platforms such as SAP, Salesforce, Microsoft Dynamics, ServiceNow, Workday and Xero through their supported APIs. Where APIs do not exist, we design and build middleware layers with appropriate queuing, retry logic, and circuit breakers to maintain application resilience when upstream systems are degraded or unreachable.

Every build includes a 30 day warranty from the day it goes live. In that time we fix bugs and any issue caused by our work at no cost. After that, ongoing support is available through a Care Plan: month to month, priced for your system. Support runs in Sydney business hours with agreed response targets. After hours cover can be added where your system needs it. If you would rather hand the application to an internal team, our documentation is written for that, and we are available for new features later. We design applications to be maintainable by teams who were not involved in the original build.

Customer facing applications introduce a broader attack surface than internal tools. Our standard security posture includes OWASP Top 10 protections built into the application layer, rate limiting and bot detection at the edge, HTTPS enforcement with HSTS preloading, CSP headers, subresource integrity for third party scripts, and regular automated dependency scanning via Dependabot or Snyk. For applications handling payment data, we keep card data out of your application by delegating it to Stripe or Windcave, which keeps your PCI DSS scope small. Security is tested throughout the build, including automated penetration testing before launch. If you want an independent penetration test by a specialist firm, we will help you arrange it.

A web app runs in a browser and works on any device without installation; a mobile app is installed from the App Store or Google Play and can use device features such as push notifications, the camera and offline storage more fully. Many products start as a responsive web app and add a mobile app, often built with Flutter, once usage justifies it.

The main drivers are the number of screens and user roles, integrations with your existing systems, whether you need web, mobile or both, and security requirements. Every build is priced on its own scope. It starts with a Discovery Audit (a fixed fee, credited in full against the build). After the audit you get a fixed price Schedule of Work with three options: The Minimum, The Recommended and The Complete. The option you choose is paid in three stages against work you have accepted. We never publish day rates. Our app development cost guide sets out typical Australian market ranges.

Build a website if people mainly need to find information about you; build an app when they need to log in and get something done. A web app runs in the browser behind a login, so customers can book, order or manage an account without installing anything. A mobile app makes sense when people use it often and it needs the phone itself, such as push notifications, the camera or offline use.

AI tools can speed up parts of the work, but they don't remove the need for engineers. AI builders such as Lovable or Bolt can produce a convincing prototype quickly. The cost sits in what comes next: security, permissions, payments, integrations, testing and keeping it running. Senior engineers lead every build and review every change, whatever tools wrote the first draft.

Yes, and it is often the cheaper path. A responsive web app proves the product with real users, ships updates instantly and avoids app store review. If we design the backend and APIs well from the start, iOS and Android apps can be added later in Flutter on the same backend, without rebuilding the core. We plan that path in the Schedule of Work so the web build doesn't lock you out of it.
