App developers in Sydney who build the app and everything behind it.
The app is the easy part.
Most mobile apps sit in front of something complex: a dispatch system, a claims workflow, a fleet operation. We build the whole thing, not just the screen.
We'll tell you which platform makes sense.
iOS, Android or React Native depends on what the app needs to do and who it's for. You'll get a straight recommendation, not the one that's easiest for us to build.
You always know where your budget is going.
We scope carefully, communicate when things change, and won't build things you don't need. Honest updates on progress and cost throughout.
What our mobile app developers build.
Smartspace (web + mobile — smart building access and management)
Web, mobile, and tablet — built as one product.
Most mobile apps are part of a larger product. We build the web platform, iOS app, Android app, and iPad app together, with shared business logic and a consistent experience across every screen. Native where performance matters, React Native where a single codebase makes more sense.

Tablet-optimised layouts for field, clinical, and enterprise use.
Business logic and APIs shared across web and mobile. Explore API integration
Web and mobile built together — no handoff problems between separate teams.
Rydo
Consumer apps built for scale from day one.
Apps for large audiences need to be fast, reliable, and easy to use under pressure. We build consumer mobile apps with real-time features, push notifications, performance monitoring, and App Store and Play Store submission handled end to end.
See our workNotifications, live updates, and feeds that keep users engaged.
Architecture that handles growth without rewrites.
We handle submission, review management, and release cycles.
Apps that keep working when the connection drops.
Eclipx Car Inspections — field inspector view.
Apps built for people doing a job in the real world.
Apps for drivers, inspectors, field teams, and clinicians work differently from consumer apps. We build for patchy connectivity, one hand occupied, and time pressure, with offline-first architecture, GPS routing, camera capture, and real-time dispatch built in.
See our workWorks without signal and syncs automatically when connection returns.
Location tracking, maps, and turn-by-turn routing built in.
Camera, barcode scanning, and document capture for field tasks.
Jobs assigned and status updated as things happen.
Smart building desk booking, connected to access control and beacon location.
Hardware integrations built into the app.
Connect mobile apps to physical hardware — beacons, scanners, sensors, and devices. We integrate Bluetooth and BLE for proximity and asset tracking, barcode and QR scanning, GPS devices, and IoT hardware, built to work reliably in field conditions.
See our workProximity detection and asset tracking via Bluetooth Low Energy.
Fast, accurate scanning built into the app without third-party hardware.
Integration with external GPS devices and location services.
Control and monitor physical devices including door locks, printers, sensors, and IoT equipment.
iPhone, Android, iPad and cross-platform apps.
iPhone and iOS apps.
Native iPhone apps built in Swift, designed for how people use their phones, with App Store submission, review management and release cycles handled for you.
Explore iOS app developmentAndroid apps.
Native Android apps built in Kotlin, from MVP to enterprise scale. We handle Play Store submission and keep the app current as Android and its devices change.
Explore Android app developmentCross-platform apps.
One React Native codebase for iOS and Android, when a shared codebase makes more sense than two native apps. We'll tell you straight which one your app needs.
Explore cross-platform app developmentiPad and tablet apps.
Tablet-optimised layouts for field, clinical and enterprise use. A standalone iPad app, or one app built for both iPad and iPhone with a single codebase.
From first conversation to the App Store, with the app and the platform behind it built together.
Scope before screens.
We work out what the app needs to do, who it's for and what has to sit behind it, and agree the requirements, a roadmap and a detailed estimate.
See it before it's built.
User flows, wireframes and interface design show you the app before development starts. The architecture is planned alongside, so the app and its platform fit.
Built and tested together.
The app and its back end are built side by side, with testing throughout so what reaches your users is stable. You see working software early, not at the end.
Launched and looked after.
We handle App Store and Google Play submission. After launch you can move into support and maintenance, which we manage, or keep developing the next version.
