Mobile & web app development

App development for iOS, Android, and the web.

We build mobile and web apps for Australian founders and product teams, from MVP to production-ready release. Cross-platform with React Native and Flutter, native when the use case calls for it, and progressive web apps when shipping to an app store would be overkill.

One team handles design, engineering, backend, and launch. You get a shippable product in weeks, not quarters.

What you get

Cross-platform

One codebase, iOS and Android. React Native and Flutter let us ship faster without sacrificing the native feel users expect.

MVP-first

We scope to the smallest version that proves the idea. Ship in weeks, learn from real users, then invest in what works.

Production-ready

Auth, payments, analytics, crash reporting, and CI/CD pipelines from day one. Built to handle real users, not just demos.

Store-ready

We handle the App Store and Play Store submission process, listings, screenshots, privacy disclosures, and review responses.

How we work

A data-driven methodology from concept to scale.

01

Discovery

We pin down the core user journey, the platforms that matter, and what success looks like at launch and three months in.

User journey map • Platform decision • MVP scope

02

Design & Prototype

Native-feeling UI for each platform. We build clickable prototypes early so you can test flows with real users before we write production code.

UX flows • Hi-fi mockups • Clickable prototype

03

Build

React Native, Flutter, or native, paired with a backend on Supabase, Firebase, or a custom API. Tested on real devices, not just simulators.

App build • Backend & API • Device QA

04

Launch & Iterate

Store submissions, analytics, and crash monitoring set up before launch. Then we iterate on what real-world usage tells us.

Store submission • Analytics • Iteration sprints

Check out the specifics

iOS apps

Native Swift or React Native, whichever fits the project. Designed for the App Store and the iPhone-first user.

Android apps

Kotlin native or cross-platform builds. Tested across the device sizes and OS versions Australian users actually run.

Cross-platform

React Native and Flutter for projects where one codebase across iOS and Android beats two native teams.

Web apps

Customer portals, dashboards, and SaaS products. Auth, billing, and admin tooling, built on Next.js, Supabase, or your existing stack.

Backend & API

Supabase, Firebase, or custom Node/Postgres backends. Auth, real-time, payments, and admin consoles wired up properly.

App store submission

We prep listings, assets, and privacy disclosures, and walk you through the App Store and Play Store review process.
