Cross-Platform App Development One codebase, both app stores, half the cost.

We build Flutter and React Native apps that ship to iOS and Android from a single codebase: near-native performance, faster time-to-market, and lower cost to maintain.

What we build

Two platforms, one great app.

A shared codebase that still feels native on each platform: the fast, cost-effective way to launch everywhere.

Flutter development

Beautiful, fast apps from a single Dart codebase with pixel-perfect UI.

React Native development

JavaScript/TypeScript apps that reuse web skills and ship to both stores.

Shared codebase

One team, one codebase, features and fixes land on iOS and Android together.

Native modules

Native code where it counts, for camera, sensors, and platform features.

Faster time-to-market

Launch on both platforms in one timeline instead of two.

Near-native performance

Smooth 60fps UI that users can't tell from native.

Where it pays off

When you need both stores, fast.

Startup MVPs

Validate on iOS and Android at once without doubling the budget.

Commerce apps

Cross-platform storefronts with a consistent brand experience.

Social & content

Media-rich apps shipped everywhere from one codebase.

On-demand

Booking and delivery apps with shared logic across platforms.

Internal tools

Employee apps that reach every device the team carries.

Lifestyle & fitness

Consumer apps that need reach without a big native team.

How we work

One build, everywhere at once.

We design a shared architecture and ship both platforms on a single, efficient timeline.

01

Discover & scope

Confirm cross-platform is the right call and define the shared feature set.

02

Design once

UX and UI designed to feel right on both iOS and Android.

03

Build shared

Flutter or React Native development with native modules where needed.

04

Launch both

Simultaneous App Store and Play Store release and rollout.

Cross-platform stack

The right framework for your app.

We help you choose Flutter or React Native based on your team, UI needs, and roadmap: then build a clean, shared codebase that's a joy to maintain.

Flutter or React Native?

Both ship one codebase to both stores. The right pick depends on your team, your UI ambitions, and where the product goes next.

Why Autech

Cross-platform done without compromise.

  • Real cost savings. One codebase means roughly 30–40% less to build and maintain than two native apps.
  • Still feels native. We tune platform-specific UI and drop to native modules so nothing feels off.
  • Ship faster. Both stores on one timeline, get to market and iterate sooner.
  • Right-tool advice. We'll tell you honestly when native is the better call for your case.
FAQ

Cross-platform, answered.

Which is better, Flutter or React Native?

Both are excellent. Flutter gives pixel-perfect UI and great performance from one codebase; React Native lets teams reuse web/JavaScript skills. We recommend based on your team, UI, and roadmap.

Will the app feel as good as native?

For the vast majority of apps, yes, users can't tell the difference. We handle platform-specific UI details and use native modules for anything performance-critical.

Is cross-platform really cheaper?

Typically 30–40% less than building and maintaining two separate native apps, because one team ships and maintains a single codebase.

When should we go native instead?

When you need cutting-edge platform features, heavy graphics/AR, or the absolute best performance on one primary platform. We'll advise honestly.

Can you migrate our existing app to cross-platform?

Yes. We can rebuild a native app in Flutter or React Native, or add a cross-platform layer, depending on your goals and timeline.
