    Cross-Platform Apps

    One codebase, both app stores

    React Native and Flutter apps that ship to iOS and Android together — faster to launch and cheaper to maintain than two separate builds.

    The right choice for most business apps. We'll tell you plainly when your product genuinely needs native instead, because paying twice for the same app is only worth it when the product demands it.

    Should you build cross-platform or native?

    Cross-platform development (React Native or Flutter) builds one codebase that ships to both the App Store and Google Play, typically cutting build and maintenance cost substantially against two native apps. Choose native when the app depends on sustained camera or sensor processing, heavy graphics, complex background work or deep OS integration. For booking, ordering, membership, content and internal business apps, cross-platform is usually the better commercial decision.

    The Service

    What is cross-platform app development?

    Cross-platform development means writing your app once — in React Native or Flutter — and compiling it to real, installable iOS and Android apps that go through the same App Store and Google Play review as any native app.

    The saving is real: one team, one codebase, one set of features to test and maintain. Most business apps — booking, ordering, membership, content, dashboards, internal tools — see no meaningful downside.

    Native still wins for heavy graphics, sustained camera or sensor processing, deep OS integrations and complex background work. We assess your feature list against that line before recommending an approach.

    Outcomes

    Real business outcomes, not vanity metrics

    Every engagement is built around measurable commercial impact — from revenue and leads to retention, efficiency and operational scale.

    Both stores launched from a single build
    Lower build and long-term maintenance cost
    Features that stay in sync across platforms
    Faster releases — one change, two stores
    Native modules added where they're needed
    A smaller team to keep the app alive
    What's Included

    What we build & deliver

    React Native builds

    TypeScript-based apps with a large ecosystem, ideal when you already have web engineering in-house.

    Flutter builds

    Dart and a rendering engine that gives pixel-identical, high-performance UI across both platforms.

    Native modules where needed

    Swift or Kotlin dropped in for the specific features that genuinely need platform code.

    Store compliance both sides

    Apple App Review and Google Play policy handled for the same release, not one at a time.

    Shared analytics & releases

    One event schema, one release process, over-the-air updates where the stores allow them.

    Shared design system

    A single component library that still respects each platform's interaction conventions.

    Who It's For

    Built for growing businesses

    Startups launching on both stores

    You need reach on day one and can't fund two engineering teams.

    Businesses with a booking or ordering app

    Standard commercial functionality that gains nothing from being written twice.

    Companies with existing React teams

    React Native lets your current web engineers contribute to the mobile product.

    Internal tools for mixed device fleets

    Staff on a mix of iPhones and Android handsets who all need the same app.

    Our process

    01

    Framework decision

    React Native, Flutter or native — decided against your actual feature list, team and roadmap.

    02

    Design system & prototype

    One design system built to work correctly on both platforms.

    03

    Shared build

    Sprint delivery with builds distributed to TestFlight and Play internal testing simultaneously.

    04

    Dual store submission

    Both listings prepared, declarations completed and both reviews managed together.

    05

    One roadmap, two stores

    Ongoing releases shipped to both platforms from the same codebase.

    FAQ

    Frequently Asked Questions

    It is building one codebase — in React Native or Flutter — that compiles to real, installable iOS and Android apps. Both go through the same App Store and Google Play review as native apps.

    React Native suits teams that already have React or TypeScript engineers and want shared skills across web and mobile. Flutter gives more consistent, pixel-identical UI and strong performance. We pick based on your team, product and roadmap, not preference.

    For most business apps, no — users cannot tell. Native still wins for heavy graphics, sustained camera or sensor processing, complex background processing and brand-new OS APIs.

    Yes, mainly because there is one codebase to build, test and maintain instead of two, and one release process instead of two. The saving compounds across every future feature, not just the first build.

    Yes. Camera, GPS, push notifications, biometrics and payments are all supported, and native Swift or Kotlin modules can be added for anything the framework doesn't cover.

    No. Apple and Google review them identically to native apps, against the same guidelines and policies.

    Often yes, though it is usually a rebuild rather than a conversion. We audit the existing app first and give you an honest view of whether the migration pays for itself.
