Overview

Our approach

Aixo Lab builds production-grade cross-platform mobile apps with Flutter — one Dart codebase that ships to iOS and Android with consistent, high-performance UI, engineered for real users in Korea and abroad.

  • Single Codebase

    One Dart codebase ships to iOS and Android, so a feature is designed, built, and tested once instead of twice.

  • Pixel-Consistent UI

    Flutter renders its own widgets, so your brand looks and animates identically on every device and OS version.

  • Native-Grade Performance

    Dart compiles ahead of time to native ARM code, and the Impeller engine keeps animations smooth at high refresh rates.

  • Fast Iteration

    Stateful hot reload turns UI changes around in seconds, which shortens design reviews and keeps MVP timelines tight.

  • Scalable Architecture

    A widget and state architecture that stays maintainable as the app grows past its first few screens.

  • Long-term Maintainability

    Null-safe, typed, and tested code with a dependency strategy built for a codebase you can still extend in two years.

What's Included

Everything under one roof

Everything included in this engagement, from architecture to long-term support — one team, one system.

Consumer Apps

Polished, store-ready consumer apps with custom animation and branded UI designed for retention, not just a working demo.

Enterprise Apps

Internal and customer-facing apps with SSO, role-based access, and integration into the systems your business already runs.

Commerce Apps

Catalogue, cart, checkout, and order-tracking apps connected to Korean payment providers and fulfilment systems.

Fintech Apps

Financial apps where transaction integrity, secure authentication, and auditability are part of the architecture from day one.

Healthcare Apps

Patient and clinician apps built with the data-handling rigor healthcare requires, including consent and access controls.

Logistics Apps

Driver, dispatch, and delivery apps with real-time location, offline support, and reliable background tracking.

Booking and Ordering Apps

Restaurant, hotel, and appointment apps built for fast, repeat use by customers and staff on the floor.

MVP and Startup Apps

Lean first versions that validate a product quickly on both stores, built on a foundation that scales into version two.
Why Aixo Lab

Why companies choose Aixo Lab

  1. We Build for Production, Not Demos

    Every Flutter app we ship is null-safe, tested, and reviewed to the same standard as our web and backend work — not a prototype dressed up as a product.

  2. We Choose Flutter When It Fits

    Flutter is the right call for brand-heavy, animation-rich, or fast-to-market apps. When another approach serves the product better, we say so during discovery.

  3. We Design for Two Platforms From Day One

    iOS and Android differ in navigation, permissions, and store rules. We design for both up front instead of shipping an Android app with an iOS skin.

  4. We Handle Native Code Properly

    Platform channels and FFI are isolated, typed, and tested, so the few native integrations you need never destabilise the rest of the app.

  5. We Own the Release Process

    App Store and Google Play review, signing, flavors, CI builds, and staged rollouts are part of the engagement, not a surprise at launch.

Our Capabilities

Our Flutter Capabilities

The specific technical capabilities behind every Flutter engagement — the actual engineering surface we work in every day.

Flutter and Dart

Core Flutter architecture — widgets, navigation, and sound null safety — built for production scale.

Custom UI and Animation

Branded interfaces, custom painters, and fluid animation that go beyond stock platform components.

State Management

Riverpod or Bloc, chosen deliberately for the app's complexity, with clear boundaries between UI and business logic.

Platform Channels and FFI

Swift and Kotlin integrations, exposed to Dart through typed platform channels, for capabilities Flutter does not cover.

Push Notifications

Reliable notification delivery and handling across both platforms, including background and terminated states.

Offline Support

Offline-first data layers that keep the app usable without a connection and sync cleanly when it returns.

Maps and Location

Interactive maps, geolocation, and background tracking, including Naver Map and Kakao Map for Korean users.

Payments

In-app payments and subscriptions with providers such as Toss Payments, PortOne, and Stripe.

Authentication

Secure sign-in with biometrics, Apple, Google, Kakao, and Naver login built on standard, audited patterns.

Bluetooth and Hardware

Bluetooth device pairing and communication for apps that connect to wearables, scanners, and IoT devices.

Camera and Media

Camera capture, QR scanning, image processing, and media handling built into the app's core flows.

Background Tasks

Dependable background execution for sync, location, and scheduled work on both platforms.

Localization

Korean and English localization, text scaling, and correct formatting for dates, currency, and names.

App Store and Google Play Release

Signing, flavors, CI builds, store submission, and staged rollouts handled as part of the engagement.

Technology Stack

Built on a modern, production-grade stack

Every technology here is a deliberate choice, not a default.

Flutter

The core cross-platform UI framework — one codebase, native iOS and Android output.

Dart

A null-safe, strongly typed language that compiles ahead of time to fast native code.

Firebase

Authentication, push notifications, analytics, and crash reporting backed by a managed service.

Google Maps

Interactive maps, geolocation, and route rendering for location-based features.

Stripe

Secure in-app payments and subscription billing for international products.

Node.js

A common backend runtime for the REST and real-time APIs a Flutter app consumes.

Swift

Native iOS code for platform channels where a capability needs it.

Kotlin

Native Android code for platform channels where a capability needs it.

Figma

Design handoff and shared design tokens, so the built app matches the approved design.

GitHub Actions

Continuous integration that runs tests and produces signed builds on every change.
Performance & Architecture

Performance & Architecture

The engineering decisions that decide whether a Flutter app stays fast and maintainable as it grows, not just at launch.

Widget Architecture

A widget tree organised around real product boundaries, with small, reusable, well-tested building blocks.

State Management

A state layer sized to the app's actual complexity, with no more machinery than the product needs.

Design System

A shared theme, typography, and component library so every screen stays consistent as the team grows.

Data and Caching

Repository and caching layers that make the app feel instant on repeat use and resilient on weak networks.

Platform Integration

Native code isolated behind typed interfaces, so platform-specific logic never leaks into the rest of the app.

Testing Strategy

Unit, widget, golden, and integration tests, plus real-device testing on both platforms before every release.

Release Pipeline

Automated builds, signing, and staged rollouts so every release is repeatable and reversible.
