Prox is Australian owned and operated, building iOS, Android and web apps for businesses across Sydney, Melbourne, Brisbane and Perth. Just build it, properly, with a team that sticks around after launch day.
Just Design, Develop, and Grow with Prox
As an app design and development agency in Australia, we run strategy, design and engineering as one connected process, not three separate suppliers passing your idea along.
As a Mobile App development company in Australia, we build for how Australian users actually behave, not a template pulled from somewhere else.
We offer mobile app development services through custom mobile app development for something complex. If you're comparing a mobile app development company for a straightforward build, we cover the whole job, native iOS and Android, cross-platform, and everything in between.
As an app design and development agency in Australia, we run strategy, design and engineering as one connected process, not three separate suppliers passing your idea along.
Half the apps that flop never had a real problem to solve, just a feature list somebody liked. We pressure-test the idea against actual user behaviour before a single screen gets designed.
Sprints Run
Launch Rate
Every discovery phase turns a rough idea into a build-ready roadmap, covering:
- Market & Competitor Audits
- User Journey & Behavior Mapping
- Feature Scoping & Prioritisation
- Platform Strategy (iOS/Android)
- Technical Feasibility Audits
- MVP Product Strategy
Users decide whether an app's worth keeping within the first few taps. We design interfaces that feel obvious straight away, no tutorial screen doing the explaining for us.
Designed
Completion Rate
Every interface gets designed for how people actually hold, tap and scroll a phone, through:
- Wireframes & User Flows
- High-Fidelity UI Design
- Interactive Prototypes
- iOS & Material Design Standards
- Onboarding & First-Session UX
- Design Systems & Libraries
Some apps need to feel like they were built for the phone, not squeezed onto it. When your product leans on camera hardware, biometrics or raw speed, we build native in Swift and Kotlin rather than force a compromise.
App Builds
Sessions
Every native build is engineered to get full performance out of the platform, through:
- iOS & Swift Development
- Android & Kotlin Development
- Hardware & Sensor Integration
- Push & Messaging Systems
- Offline-First Architecture
- App Performance Tuning
Most apps don't need two separate codebases to feel right on two different phones. We build in React Native and Flutter to land on the App Store and Google Play together, and pair it with web app builds when the product calls for both.
Builds
Vs. Dual-Native
Every cross-platform build runs on one codebase engineered to perform like two native ones, through:
- React Native Development
- Flutter Development
- Cross-Platform Architecture
- Web & CMS Integrations
- API & SDK Integrations
- Nonstop Integration & Deployment
A great app on a shaky backend is just a great app that falls over the first time real traffic shows up. We build the servers, databases and APIs your app actually leans on.
Systems Built
Managed Apps
Every backend build is engineered for real-world load, not a demo environment, through:
- API Design & Development
- Cloud Infrastructure (AWS/Azure/GCP)
- Database Design & Architecture
- Payment & 3rd-Party Integrations
- Authentication & Data Security
- Scalable Server Architecture
Getting an app approved by Apple and Google is its own project, and failing during your launch week is a pain you cause yourself. We test properly, submit clean, and stick around once it's live.
Store Approvals
Monitoring
Every launch is backed by real testing and real support, not a handover and a goodbye, through:
- Manual & Automated QA
- Device & OS Compatibility
- App Store & Google Play Submission
- App Store Optimisation (ASO)
- Crash Monitoring & Bug Fixes
- OS Updates & Maintenance

The App Problems Quietly
Burning Your Budget
People download the app, have a poke around once, and never open it again, because the first session never gave them a reason to come back.
Schedule a call
Picking the wrong tech stack early gets expensive fast, either overpaying for native when you didn't need it, or hitting a wall cross-platform can't clear.
Schedule a call
A rushed submission gets bounced by Apple or Google, pushing the launch date and burning the marketing spend you'd already committed.
Schedule a call
An app that works fine in testing can buckle the moment real users show up, right when the attention you paid for finally arrives.

Operating systems update, devices change, and an app with no maintenance plan quietly breaks within a year of shipping.

The Stories Behind
The App Store Rating
I have engaged several agencies in India; they were proficient with templates and development, yet lacked the innovative ideas we sought upon discovering Prox Digital Agency, their vibrant and imaginative work convinced me that they are the ideal partner for our vision
Prox Design has delivered exceptional results, profoundly transforming both our brand identity and lead‑generation pipeline. The entire team demonstrated professionalism, responsiveness, and a genuine commitment to our success.
During the initial call with Prox, I felt an immediate confidence that eliminated the need to consider any other agency. Their professionalism and innovative redesign of our website delivered exceptional results. I look forward to partnering with them for our digital marketing initiatives
Prox Design spearheads our marketing strategy, significantly enhancing our brand presence. Their efforts have generated higher‑quality leads and deeper audience engagement. I give them my highest recommendation
When you're building a brand, every detail starts to matter. Prox Digital Agency helped us connect the new identity with the website so they actually feel like the same business. Really happy with the direction. The result is more confident and much easier to build on.
I’d worked with a few designers before, but none of them really got what I was trying to say with my brand. Prox Design Studio actually listened. They picked up on the tone, the vibe, the whole story behind it, and you can see that in every little detail. The colors, the layout, everything just felt right.
Most designers I worked with before just made things look nice but didn’t get what I was trying to say. Prox Design Studio was different. They actually took the time to understand my content and what it meant. The posts they made didn’t just look good—they helped tell the story I wanted to share. My feed finally feels like me, and people have noticed the difference.

Frequently
Asked Questions
We’ve heard it all. Here’s everything you need to know before working with us.
Mobile app design and development covers everything from the initial idea through to a working product on the App Store and Google Play, strategy, UI/UX design, native or cross-platform engineering, backend infrastructure and testing. Skipping any one of those steps is usually where projects come unstuck.
Most app design and development shops hand your project between separate design and engineering teams. Prox runs both under one roof, so nothing gets lost between the first wireframe and the finished build, and you're not stuck being the go-between.
No. We're Australian owned and operated, working with clients across Sydney, Melbourne, Brisbane and Perth, plus a fair few businesses further afield. A proper mobile app development company shouldn't be limited to one postcode.
Native Swift for iOS, Kotlin for Android, or React Native and Flutter for cross-platform builds, whichever actually fits the product. Mobile app design decisions come first, the tech stack gets chosen to serve that, not the other way around.
Every project starts with proper discovery and a signed-off scope, then we design the full app UI before a line of code gets written. You see wireframes, prototypes and app design mockups at every stage, not just a finished build at the end.
Most apps take somewhere between two and five months depending on scope, platform count and backend complexity. A proper Mobile App development agency should give you a real timeline upfront, not a vague guess.
Cost depends on scope, platform choice and backend complexity. As a guide, most custom mobile app development projects in Australia land somewhere between straightforward MVP pricing and a fully custom enterprise build, and any agency worth hiring will break costs down by feature before you sign anything.
Enormously. A sharp app design and development process is what separates an app people tolerate from one they actually enjoy using. Good mobile app design isn't decoration, it's most of why people stick around past the first open.
Yes. Our mobile app design and development company approach covers everything from early app design inspiration and wireframes through to a full app UI design system your team can keep using after launch.
Both, and we'll help you decide which to launch first if budget makes that the smarter move. Most app development agency Australia projects launch cross-platform now, since it gets you on both stores without doubling the build.
It happens, usually over a policy detail nobody flagged early. We test against submission guidelines before we ever hit submit, and if a rejection does come through, we fix and resubmit fast instead of leaving you stuck mid-launch.
Yes. Every build includes post-launch monitoring, bug fixes and updates to keep pace with new iOS and Android releases. A mobile app development company Australia businesses can actually rely on shouldn't disappear the day after launch.
No. Small businesses and startups make up a good chunk of our mobile app development Australia work, especially once a spreadsheet or an off-the-shelf tool stops being able to keep up with the business.
Everything's custom. We don't work off a generic app template or app design template stretched to fit your brand, every mobile app template you might have seen elsewhere gets left behind in favour of a mobile user interface actually built around your users and your business.
