Development

Native iOS and Android apps that users love, and cross-platform solutions when one codebase makes sense. We ship to the App Store and Google Play — from design through launch and beyond.

Deliverables

What's included

Native iOS Development
Swift and SwiftUI apps built to Apple's Human Interface Guidelines. Deep integration with iOS features — Face ID, HealthKit, ARKit, widgets, and Live Activities.
Native Android Development
Kotlin and Jetpack Compose apps that feel at home on Android — Material You design, adaptive layouts, deep linking, and full Google Play compliance.
Cross-Platform (React Native / Flutter)
One codebase, two stores. React Native or Flutter for when parity across iOS and Android matters more than platform-native nuances — without sacrificing performance.
Push Notifications & Engagement
Targeted push notification infrastructure, in-app messaging, deep links, and onboarding flows — the engagement mechanics that turn downloads into daily active users.
Offline-First Architecture
Sync engines, local-first storage, and conflict resolution — so your app works seamlessly with no signal and syncs automatically when connectivity returns.
App Store Launch & ASO
Full submission process to App Store and Google Play — screenshots, metadata, review compliance, and App Store Optimisation to maximise organic discoverability.

How It Works

Our mobile build process

01
Design
UX flows, interaction design, and prototype in Figma. Reviewed with real users before any code is written — so we build the right thing, not just build it right.
02
Prototype
Functional prototype delivered to TestFlight / Firebase Distribution within 3 weeks so you can test with real users and course-correct early.
03
Build & QA
Full feature development with automated UI tests, performance profiling, accessibility audits, and device coverage across the device matrix.
04
Launch & Grow
Store submission, phased rollouts, crash monitoring from day one, and ongoing iterations driven by analytics and user feedback.

Questions

Mobile development FAQ

It depends on your users' expectations, budget, and how platform-specific your features need to be. For consumer apps where feel and performance are paramount, native often wins. For internal tools, B2B products, or teams that want to move fast across both platforms, React Native or Flutter is frequently the smart choice. We'll help you decide based on your specific situation.

A focused MVP typically takes 8–14 weeks from kickoff to App Store submission. Fully-featured consumer apps can take 4–6 months. Timeline depends on complexity, number of integrations, and how quickly design decisions are finalised. We can show you a detailed timeline after a discovery call.

Yes, completely. We handle the submission, respond to review feedback, manage certificates and provisioning profiles, and set up automated CI/CD pipelines (via Fastlane) so future releases are one-click deploys. You maintain ownership of the developer accounts.

Yes. We start with a code and architecture review to understand the state of the app, document what's there, and establish a path forward. Many of our longest-running client relationships began as rescues of apps with mounting technical debt or an outgoing dev team.
