Webshark provides app development and custom software development for Sydney businesses, from start-ups in Surry Hills and Pyrmont to established firms in the CBD, North Sydney and Parramatta. Our app developers build iOS, Android and Flutter apps for fintech, health, retail, hospitality and professional services, and the same team delivers custom software, SaaS products, integrations and IT consulting. We work remotely, and because India is only 4.5 to 5.5 hours behind Sydney, our teams share most of your working day for stand-ups, demos and calls. Sydney clients get senior engineering at a fraction of typical local agency rates, with every project following ISO 27001 certified and Privacy Act-aligned processes. Looking for a national partner?

Our app developers overlap with most of the Sydney working day, join your Slack or Teams, share builds every two weeks and report progress weekly, so remote delivery feels close and predictable.
We follow ISO 27001 and CMMI Level 3 processes, code reviews and automated testing, while our delivery model keeps costs well below typical Sydney agency rates.
A proven process takes you from idea to launch.
Our app developers in Sydney begin with discovery workshops scheduled in AEST or AEDT, usually over one to two weeks. We map your users, business goals, competitors and revenue model, then prioritise features into a lean MVP scope. For fintech, property and health apps we also flag compliance needs early. You receive a product brief, user journeys, a feature backlog and a fixed estimate, so investors or stakeholders can sign off with confidence.
Designers turn the user journeys into wireframes and then polished iOS and Android screens that follow Apple and Google guidelines. We build clickable prototypes you can test on your phone and share with customers or your board before any code is written. Expect two to four weeks and one or two feedback rounds. The result is an approved design system and screen set that removes costly rework during app development.
Our architects choose between Flutter, React Native or native Swift and Kotlin, then design the backend, database and APIs. Sydney apps commonly need integrations such as Stripe, Afterpay, Xero, property listing feeds or booking platforms, so we document each one up front. You receive an architecture document covering hosting in Australian cloud regions, security controls and scalability, giving your app a stable foundation as user numbers grow.
Development runs in two-week sprints, each ending with a demo and a test build you can install on real devices through TestFlight or Google Play internal testing. You see progress every fortnight, give feedback while changes are still cheap, and can reprioritise features as market feedback arrives. A dedicated project manager keeps a live backlog and reports on progress, budget and risks during Sydney business hours.
QA runs alongside development, not just at the end. We test on a range of iPhones and Android devices, check performance on slower mobile networks, and verify payments, notifications and integrations. Accessibility checks cover screen readers, contrast and text scaling, and security testing follows OWASP mobile guidance, which matters for fintech and health apps. You receive test reports and a list of resolved issues before every release.
We prepare App Store and Google Play listings, screenshots, privacy disclosures and release notes, then handle submission and answer any reviewer questions. Launch is timed for Sydney business hours so we can watch crash reports, analytics and server load in real time. You receive the published apps, admin access to your developer accounts and a launch checklist, with our team on standby for quick fixes in the first weeks.
After launch we monitor crashes, performance and server health, keep the app compatible with new iOS and Android releases, and apply security patches. Based on analytics and user feedback, we plan new features in monthly or quarterly releases. Support plans are sized to your app, and our team overlaps with most of the Sydney working day, so issues and new ideas move quickly from request to release.

Answers to the questions Sydney businesses ask before hiring app developers: cost, time zones, platforms and support.
App development in Sydney with Webshark typically costs AUD 30,000 to 70,000 for a simple app, AUD 70,000 to 160,000 for a mid-complexity app and from AUD 160,000 for complex platforms. That is well below typical Sydney agency rates, because our app developers deliver remotely from India. Cost depends on the number of screens and user roles, whether you need iOS, Android or both, integrations such as Afterpay, Stripe or Xero, admin dashboards, real-time features and compliance needs for fintech or health data. We provide a fixed quote after a short discovery phase.
No, we do not have a physical office in Sydney. We work with Sydney clients remotely from our Bengaluru headquarters and Mumbai office. India is 4.5 hours behind Sydney during AEST and 5.5 hours behind during daylight saving, so our teams overlap with most of your working day for stand-ups, demos and reviews. Each project has a named project manager, shared Jira or Trello boards, Slack or Teams channels and regular video calls, so communication stays as clear as it would with a local studio.
Yes. Beyond mobile apps, we build custom business software, SaaS products, customer and partner portals, internal dashboards and system integrations for Sydney businesses. Typical projects include lending or property management platforms, booking engines for hospitality groups, practice tools for professional services firms and workflow systems that replace spreadsheets. Custom software follows the same discovery, design and two-week sprint process as our app projects, and can share one backend with your mobile app, which reduces long-term cost and keeps data consistent.
Yes. We provide remote IT consulting for Sydney businesses that need clear technology direction before investing. Engagements cover technology strategy, architecture and code reviews, build versus buy decisions, cloud migration planning and AI roadmaps. Our consultants are senior engineers who build software every day, so recommendations are practical and costed. Typical outputs include a current-state assessment, options with trade-offs and a phased roadmap. Many Sydney clients use consulting to validate an app idea or rescue a stalled project before committing to a full build.
An MVP usually takes 8 to 12 weeks, and a full-featured app takes 3 to 6 months. That covers one to two weeks of discovery, two to four weeks of design, development in two-week sprints, testing and App Store submission. Apps with complex integrations, real-time features or regulated data, such as fintech or health apps, sit at the longer end. You can shorten time to market by launching a focused MVP first, then adding features based on real usage data from your Sydney audience.
Sydney businesses choose Webshark because they get experienced app developers at well below local agency rates without losing communication or quality. We have delivered 580+ projects for 280+ active clients across 18+ countries over more than seven years, under ISO 27001 certified security and CMMI Level 3 processes, and we run our own live apps, including Webshark Health on iOS and Android. One team handles strategy, design, development, QA and support. Our hours overlap with most of the Sydney working day, and you own all code and IP from the start.
Yes. Alongside apps, we build business websites, web applications, ecommerce stores and admin portals for Sydney and Melbourne businesses. Many app clients also need a marketing website, a web version of their product or a dashboard for staff, and building them with the same team keeps design, data and logins consistent. Websites follow our usual discovery, design and testing process, with fixed pricing in AUD. For platforms, pricing and timelines, see our web development page.
Yes. Most Sydney clients start small with a two to three week discovery sprint or a focused MVP, then scale once they see results. Discovery gives you a validated scope, prototype and estimate you can take to investors or your board. An MVP puts a core version of your app in front of real users, so you learn what they value before spending on extra features. Because our team works in two-week sprints, you can pause, expand or reprioritise at each stage based on budget and traction.
For apps we build cross-platform with Flutter or React Native, or natively with Swift and Kotlin when performance or device features demand it. Backends use Node.js, Python, Java Spring Boot or .NET, with web dashboards in React, Next.js or Angular, hosted on AWS, Azure or Google Cloud. For Sydney clients we usually deploy to Sydney cloud regions, keeping customer data in Australia. We pick the stack that fits your goals, budget and in-house skills, so your own developers can take over later if you choose.
You do. All source code, designs, documentation, app store listings and infrastructure scripts from your app and software development project belong to your business, and repositories sit in accounts you control. We sign a mutual NDA before discovery starts and include IP assignment in every contract. Personal information is handled in line with the Privacy Act 1988 and the Australian Privacy Principles, and our ISO 27001 certified processes control who can access your code and data during the project.
Yes. Instead of a fixed-price project, you can hire dedicated app and software engineers on monthly contracts. Teams range from one developer to a full squad with Flutter or native developers, backend engineers, a project manager and QA. Your team works hours that overlap with the Sydney business day, joins your stand-ups and uses your tools. This model suits Sydney start-ups and scale-ups with evolving roadmaps that need to add or reduce capacity quickly. To see roles and engagement options, visit our hire full-stack developers page.
Yes. Our app support plans cover iOS and Android OS updates, bug fixes, crash and performance monitoring, security patches, backend maintenance and new feature releases. Each plan includes an agreed number of hours, so you can balance routine maintenance with improvements suggested by analytics and user feedback. We also renew certificates, handle app store policy changes and keep third-party SDKs current. Our support team overlaps with the Sydney working day, so issues are triaged while your business is open.
