Native Android and iOS Application Development

Native Android and iOS application development produces two separate apps, one in Kotlin and one in Swift, over a shared backend. It suits apps that depend on device hardware or must match each platform exactly.

When two native apps are justified

Deep hardware use

Continuous camera work, Bluetooth peripherals or sensors read through the working day are usually more dependable in native code, which reaches the hardware directly. Shared frameworks add a layer in between.

Platform features first

Widgets, wallet passes and system integrations usually arrive natively before they reach shared frameworks. Native code can use them on day one.

Long service life

Software that runs for years benefits from few surprises at each operating system update, and native code follows the platform’s own changes closely. Fewer layers means fewer breakages.

What two codebases involve

Shared backend

One API and one database serve both apps, and the business rules stay there. Neither app carries its own copy of the logic.

Design per platform

Navigation follows each platform’s own conventions, and one look is not forced onto both. Users find things where they expect them.

Separate release cycles

Two sets of tests and two store reviews apply. A fix may reach Android first and the iPhone app later. The second platform does not cost half the first.

Publishing under your own name

Your developer accounts

Store listings, keys and certificates are held by your company and not by the developer who wrote the code. Ownership is clear.

Store assets

Screenshots, descriptions and privacy declarations are prepared for both stores. This is done before submission, not after a rejection.

Handover

Source code, signing keys and build steps are passed over, so another team can take the apps forward.

FAQ

Frequently asked questions

Are native apps better than cross-platform ones?

No, not automatically. Native apps do better on hardware access and platform feel, but they cost more and release more slowly. For most business apps a shared codebase is the first option worth weighing.

Can we build one platform now and the other later?

Yes. The backend is built so the second app can follow later without rework behind the scenes. Which platform goes first is decided during scoping, based on who will use the app.

Who maintains the apps afterwards?

Either GullySystem under a support arrangement, or your own team once the code and keys are handed over. Both apps need attention whenever the operating systems change. Plan for that.
