Service Overview

Maintaining two separate native engineering teams for iOS and Android doubles your upfront build budget and slows down every future feature release. At 360 Web Coders in Wallington, Surrey, we build bespoke Cross Platform Apps using Google Flutter and Meta React Native so UK businesses can launch simultaneously on the Apple App Store and Google Play from one unified codebase. Unlike outdated web wrappers, Flutter compiles Dart directly to native ARM machine code with its Impeller rendering engine, while React Native’s New Architecture bridges TypeScript directly to native UI components. We write custom Swift and Kotlin platform channels whenever hardware-specific biometrics, Apple Pay, or Bluetooth integrations are needed, giving you true native quality at up to 40% lower total cost of ownership.

CROSS-PLATFORM APPS FAQ

Cross-Platform App Development Frequently Asked Questions

Honest answers comparing Flutter vs React Native, UK cross-platform pricing, native performance, and dual-store publishing.

Cross-platform app development in the UK using Flutter or React Native typically costs between £8,000 to £16,000 for an iOS and Android MVP, £16,000 to £32,000 for a full commercial dual-store app, and £35,000+ for enterprise platforms, saving roughly 35% to 40% compared to two separate native builds.

Choose Flutter if you want ultra-consistent custom animations, high 120fps rendering speed, and a self-contained UI engine. Choose React Native if your internal team already uses React/TypeScript on the web and wants to share logic across web and mobile.

Yes. Modern Flutter compiles directly to native ARM machine code and React Native’s JSI architecture communicates synchronously with native views, delivering 60fps to 120fps performance indistinguishable from native apps for 95% of business use cases.

Yes. Whenever your app requires hardware-level features like FaceID, Apple Pay, Google Pay, NFC, or Bluetooth Low Energy, our engineers write native Swift and Kotlin platform channels inside your Flutter or React Native project.

Most bespoke Flutter and React Native apps launch simultaneously on the Apple App Store and Google Play in 8 to 14 weeks from initial kick-off.

Yes. We regularly consolidate separate iOS and Android legacy apps into a single clean Flutter or React Native codebase while preserving existing user accounts, deep links, and App Store ratings.
