Cross-Platform App Development Done Honestly

One codebase, both stores, about half the cost of building native twice — and a straight answer when cross-platform is wrong.

Cross-platform MVPs from $5,000–$12,000 — roughly half the cost of building the same app twice in Swift and Kotlin.

Service Overview

Cross-platform means building once and shipping to both stores. Done well — in **React Native**, with native modules where needed — it halves the cost and keeps both apps permanently in sync. Done badly, it produces the laggy web-view apps that gave the category a bad name. The difference is the developer, not the framework. Four of my production apps are cross-platform; none of them are web views.

Core Benefits

  • ~85-90% of code shared — build features once, ship twice
  • Both apps stay in sync forever; no platform falls behind
  • Real native UI components, not a website in a wrapper
  • Roughly half the build and maintenance cost of dual native

How It Works

  1. 1Scope call — and an honest check that cross-platform fits your app at all
  2. 2One shared codebase; native modules cover the platform-specific edges
  3. 3Simultaneous release to the App Store and Google Play
  4. 4Every later feature ships to both platforms at once, forever

Frequently Asked Questions

What is cross-platform app development?

Building one codebase that produces real apps for both iOS and Android, instead of writing everything twice in Swift and Kotlin. Modern frameworks like React Native render genuine native components — this is not the web-view wrapper approach of a decade ago.

How much cheaper is cross-platform than native?

Roughly half, both upfront and ongoing — 85-90% of the code is shared, so every feature and every fix is built once. The saving compounds: two native codebases drift apart over time and double every estimate forever.

Is cross-platform performance good enough?

For the overwhelming majority of apps — bookings, marketplaces, social, content, health, fintech UI — yes, indistinguishable from native. The exceptions are games, heavy background processing and hardware-intensive apps, which belong in native code.

React Native or Flutter for cross-platform?

I build in React Native, primarily for hiring: it's TypeScript, so the developer pool is enormous, while Flutter's Dart is rarely used elsewhere. Both are capable frameworks — the hiring difference is what matters to a startup over years.

When should I avoid cross-platform entirely?

Bluetooth-heavy hardware apps, continuous background processing like always-on tracking, and high-end 3D games. If your app is one of those, I'll tell you to go native — in writing — rather than sell you the wrong architecture.
