Cross-Platform App Development

We build cross-platform apps with React Native and Flutter — one codebase, two App Stores, and a UI that still feels native on each.

Overview

Cross-platform makes sense when you need to be on both iOS and Android without funding two separate native teams. The trade-off is real, so we scope honestly upfront: which parts of your app benefit from shared code, and where native modules are worth the extra effort.

We choose React Native or Flutter based on your specific requirements — team preferences, third-party SDK availability, and how animation- or performance-heavy the app is — rather than defaulting to one framework for every project.

Where a feature genuinely needs platform-specific code (certain camera APIs, background processing, deep OS integrations), we write native modules rather than forcing a workaround that degrades the experience.

Our Process

1

Discovery & framework selection

We assess your feature list and pick React Native or Flutter based on fit — not habit — and flag anything that will need native modules.

2

Shared-codebase development

Weekly milestones with builds testable on both platforms simultaneously, so divergence gets caught early.

3

QA across both platforms

Parallel testing on iOS and Android devices — cross-platform doesn't mean testing once and assuming parity.

4

Dual submission & launch support

Coordinated App Store and Google Play submissions, then a post-launch window covering both platforms.

FAQs

React Native or Flutter — which is better?

Neither is universally better; it depends on your app. React Native fits teams with existing React/JS experience and a large plugin ecosystem; Flutter tends to win on rendering consistency and animation-heavy UIs. We'll recommend one after discovery, with reasoning specific to your app.

Will a cross-platform app feel native?

Done well, yes for the vast majority of screens. For the small number of features that need true native performance or OS-level integration, we write native modules rather than accepting a degraded experience.

Is cross-platform actually cheaper than building native twice?

Generally yes for the shared business logic and UI, since it's written once. The savings shrink for apps that need heavy platform-specific functionality — we'll be upfront about that during scoping rather than after you've signed.
