Growth Obstacles

Problems This Solves

!

You need an app on both iOS and Android but building two separate native codebases doubles your development cost and timeline.

!

Your existing cross-platform app (React Native or Ionic) has performance issues — janky animations, slow transitions, and inconsistent UI across platforms.

!

You want a pixel-perfect, custom UI that matches your brand identity but platform-default components look generic on both iOS and Android.

!

Your MVP needs to ship in 8-12 weeks and you cannot afford the 16-24 week timeline of building separate native apps.

Methodology

Our Proven Process

1

Requirements & Architecture

We define feature scope, user flows, API requirements, and technical architecture — choosing the right state management, backend, and deployment strategy for your Flutter app.

2

UI/UX Design in Figma

We design all screens in Figma with platform-adaptive layouts that feel native on iOS, Android, and web — following Material 3 and Cupertino design guidelines.

3

Flutter Development

We build your app using clean architecture patterns (BLoC/Riverpod), custom widgets, smooth animations, and platform-specific adaptations.

4

Backend & API Integration

We connect your app to Firebase, Supabase, or your custom backend — implementing authentication, real-time data sync, push notifications, and offline support.

5

Testing & Store Deployment

We write widget and integration tests, configure CI/CD with Codemagic or GitHub Actions, and handle App Store and Play Store submission.

Frequently Asked Questions

For 90% of apps, yes. Flutter compiles to native ARM code and achieves 60fps performance. The remaining 10% — apps requiring heavy platform-specific APIs (e.g., complex AR, low-level Bluetooth) — may still benefit from native development.
Yes. Flutter supports iOS, Android, web, macOS, Windows, and Linux from a single codebase. Web support is production-ready and ideal for admin dashboards, landing pages, and progressive web apps.
For speed: Firebase or Supabase. For scale: custom Node.js or Python API. We choose based on your data complexity, real-time requirements, and budget. All options support authentication, storage, and push notifications.
Yes. Upon project completion, you receive full ownership of all source code, design files, and assets. We use Git for version control and hand over the complete repository.
