Web Application & PWA Development in Sydney & Melbourne

A website mainly publishes information for visitors, such as services, articles and contact details. A web application lets signed-in users do things: manage accounts, submit and approve work, see live data or run a process. If you need a marketing website, see our website design and development service. If people need to log in and work, this page is the right one.

Yes, with limits that matter. Apple says that from iOS 26 every website added to the Home Screen opens as a web app by default, unless the user turns off Open as Web App, and that a web app does not need a service worker, although one can improve the experience. Some capabilities that Android users take for granted are still missing or restricted on iPhone, so we test the features you need on real iPhones before recommending a PWA. Check current WebKit support, as it changes with each release.

Often yes. A third-party guide updated in March 2026 reports that web push on iPhone arrived in iOS 16.4 and works only after the user adds the web app to the Home Screen. That requirement changes how you design the prompt and the onboarding. Confirm current behaviour against Apple's documentation before you plan around notifications.

It can be one option, but it is not a loophole. In August 2025 the Federal Court found that Apple and Google breached Australian competition law through restrictions on alternative payments and app distribution. The relief stage was still being heard in 2026, with the ACCC granted leave to intervene on remedies. Until orders are made and the store terms change, check the current Apple and Google rules before you plan a payment or distribution strategy around the court case. Selling a subscription on the web outside an app may be possible, and the rules differ by store. Confirm with an adviser.

Google's Core Web Vitals give a clear starting target: a page is rated good when Largest Contentful Paint is 2.5 seconds or less, Interaction to Next Paint is 200 milliseconds or less and Cumulative Layout Shift is 0.1 or less, measured at the 75th percentile of real visits. We agree on a speed budget with you before building, test on mid-range phones and slow connections, and report real results. We do not promise perfect scores, because they depend on your content, devices and network.

The Disability Discrimination Act 1992 may apply to your web application, and a respondent to a complaint must show unjustifiable hardship, which cannot be assumed. The Australian Human Rights Commission's older advisory notes recommended WCAG Level AA, although those notes are archived and marked no longer current, so confirm the current position with an adviser. We build with keyboard use, labels, headings and contrast in mind, and we test with assistive technology. Automated tools alone do not prove accessibility.

We build multi-factor authentication, role checks, audit logs and secure data handling from the start, and we map who can see what before building. If your app makes automated decisions about people using their personal information, the 10 December 2026 privacy changes may require disclosure in your privacy policy. See our customer and partner portal work. Confirm your own obligations with an adviser.

It depends on the number of user types, the workflows, the integrations, and the testing and security your risk requires. A focused tool for one team is much smaller than a multi-role platform. We scope a first release before quoting, and we do not quote from a feature list alone.
