What cross-platform app development actually is

One codebase that ships to the App Store and Play together, at roughly half the cost

Cross-platform means one codebase for both stores, at roughly half the cost.

Cross-platform · one codebaseONE SOURCEwebzenia/appmainshared code95%one source, both storesFlutterReact NativeBOTH STORESApp StoreWebzenia App4.8GETGoogle PlayWebzenia App4.7InstallOne codebase, both stores, half the cost.

One codebase, both stores

A single project ships to iPhone and Android, so you maintain one app, not two, and ship a fix to both stores at once.

Flutter or React Native

We pick the framework on fit. Flutter for pixel control and animation, React Native for a JavaScript team and web reuse.

Native where it matters

Camera, payments, Bluetooth and the parts that need the metal drop to native modules, so nothing is left half-built.

Cross-platform, or two native builds

When one codebase wins, and when native is worth two

Cross-platform wins when both stores on a budget matter most; native wins when the last 10% of platform feel is the product. We tell you which, before the build.

Not sure which you need?

If the feel is the product and your audience is on iPhone, see iOS app development; for the Android half built native, see Android app development. If you need both stores on one budget and a fast launch, cross-platform is the call. We help you decide in the first conversation.

How we build cross-platform

Built for the budget and the timeline an Indian launch actually has

Cross-platform is mostly an economics decision: one team, one codebase, both stores. We make the framework and native-module calls in the open, so you ship the right app, not the cheapest-sounding one.

  1. 01of 04
    Budget and time-to-marketOne runway

    Most Indian startups cannot fund two native builds and two teams at launch.

    Cross-platform lands the same app on both stores for roughly half the cost and time, which is usually the difference between a launch this quarter and a launch next year. We scope to your runway.

    Our methodOne codebase, both stores, one budget.
  2. 02of 04
    Flutter or React NativeChosen on fit

    The framework is a fit decision, not a default we apply to every project.

    We pick Flutter when pixel control and animation matter, React Native when you have a JavaScript team or want web reuse. The call is made after we see the app, and we tell you why.

    Our methodFramework chosen after the audit, not before.
  3. 03of 04
    Native where neededNo half-built features

    Cross-platform breaks when a team avoids native code instead of writing it.

    Camera, payments, Bluetooth and background work drop to native modules in Swift or Kotlin where the framework cannot reach. Nothing is left half-built to keep the codebase pure.

    Our methodNative modules for device-level work.
  4. 04of 04
    Both stores, one teamShipped together

    Two stores kept in step by two teams is where releases drift apart.

    One Webzenia team ships the App Store and Play release together, so the same version, the same fix and the same feature land on both phones at once, not weeks apart.

    Our methodOne team ships both stores together.

What the engagement covers

From idea to a live listing on both stores, end to end

Not a contractor for hire. Discovery, the framework call, the build, native modules, device testing, both-store review and the handover.

Tools we use to ship once, run everywhere

The stack behind one codebase that ships to both app stores.

Flutter
Why Flutter

Flutter compiles to native for both platforms from one codebase, with its own engine for consistent, fast UI everywhere.

How we excel

We pick Flutter when pixel-consistent UI across platforms matters, because its own rendering engine makes the app look and behave identically on iOS and Android.

Our commitment

Our commitment, in writing

A cross-platform build goes wrong when the wrong framework is forced on the app, when native features are skipped to keep the code pure, or when the IP is unclear. We build against all three.

  • You own the IP

    Your repo, your App Store Connect and Play Console, and full IP, with a clean handover. The app is your asset, not ours.

  • The honest framework call

    We pick Flutter or React Native on fit, and tell you plainly when native is the right call instead, because we build both.

  • Native where it matters

    Camera, payments and device features drop to native modules, so no feature is left half-built to keep the codebase pure.

  • A senior team, named

    Senior cross-platform engineers on your build with one accountable lead, not a rotating junior bench.

Your app is your asset: code, both store listings and all.
