One codebase for iOS and Android, native where it counts

A React Native app isn't worse than a native one for screens and data, because it uses the phone's own views. It looks like any other app on your phone. You'd see a gap in heavy animation and constant sensor work. Those parts can be written natively inside the same app, so you don't have to pick one approach for the whole thing.

A cross-platform app development company builds one codebase that ships to both the App Store and Google Play. It writes the native pieces the shared code can't cover and handles both store submissions. Hashlogics does this with React Native and Expo, from East Islip, New York, with engineering in Lahore.

Choose React Native when your team already knows React or the app should feel like the phone it runs on. Flutter is the better pick when a custom brand design must look identical on every device, since it draws its own widgets. Both share one codebase, and both call platform code for some hardware features.

Build native in Swift and Kotlin when the hardware is the product, such as a camera app or one that reads sensors all day. Native also fits an app that must adopt new operating-system features the week they ship. If only one or two features need the device, a cross-platform app with native modules for those parts often costs less to keep running.

A hybrid app isn't the same as a cross-platform app: it runs web code inside a native shell, the approach Cordova and Capacitor take. React Native, by contrast, creates real iOS and Android views. Hybrid makes sense when you already have a web app and need a store listing. Apple asks that an app go beyond a repackaged website, so a thin wrapper needs real app features.

We can add native features to an existing React Native app with a Turbo Native Module. That's React Native's documented route for a platform API it doesn't provide: platform code called from the shared app. In the Blueprint we read your codebase and list which features need one and which an existing library already covers.

With one codebase covering both stores, the cost turns mostly on how many features need native code on each platform. Offline work and the systems the app talks to add to it, so we read your feature list before naming a number. Your scoping call is free. Then a fixed-fee Blueprint sets a fixed price for each milestone, and its fee is credited in full against the build. If the Blueprint doesn't give you a plan you'd act on, you don't pay for it.

You own the one React Native codebase from day one, with the source code and the data. That single repository builds the iOS release for your App Store account and the Android release for your Google Play account. Your own team or another firm can carry it on from there.

Startups and enterprises both build cross-platform, but the native share differs. A startup usually needs one workflow on both stores, so the shared code carries nearly everything and native modules come later, feature by feature. An enterprise app may need a vendor's SDK, such as one for device management, wrapped on each platform. Our mobile app development page covers the wider enterprise points.

After launch, small fixes to the shared JavaScript can go out over the air with EAS Update. New features and native changes still go through store review on both platforms. The first 2 months of maintenance are included with every build. After that, an agreed service level covers OS updates and store deadlines, or we hand the app to your team with documentation and training.
