Native Apps for iOS and Android (Swift and Kotlin) - Zephyra Studio

What native iOS and Android apps are, and who they are for

Native mobile development means building the iOS app in Swift (Apple's language, using Apple's own tools) and the Android app in Kotlin (Google's language, on Google's own stack). Each app is written for one platform only, using that platform's own interface components, so the result looks and behaves exactly like the rest of the phone and follows every system convention. There is no shared middle layer between the two.

This is not the right default for every project, and we say so plainly. Native is for teams whose app genuinely leans on the device or on performance: applications with intensive graphics, AR experiences, real-time features such as live tracking or video processing, or sensors and hardware that must be driven directly. It is also the honest answer when a product has outgrown a cross-platform build and needs to be pushed further. If your app is mostly content, bookings, or e-commerce, cross-platform is usually the better economics and we will advise that instead.

Because you maintain two separate codebases, native carries a higher cost and a longer timeline, and that trade is worth it only when the app itself is what sets you apart. This page is about the cases where that is true.

Native compared with cross-platform such as React Native or Flutter

The main alternative is cross-platform, where one codebase runs on both iOS and Android. Cross-platform wins decisively on cost and speed, and it is the right choice for most small and mid-sized apps. The reason native still exists as an option is what happens at the edges: the heaviest animation, the most demanding graphics, the tightest real-time response, and direct access to hardware features.

Those edges are real but specific. If your app plays a lot of video, runs a camera-based AR view, processes sensor data frame by frame, or needs every bit of responsiveness in a fast-moving interaction, cross-platform frameworks will fight you, and the extra work to bend them can erase the savings. Native also gives the most direct path to platform APIs on the day they ship, so features tied to a new iOS or Android release can be adopted without waiting for a third-party layer to catch up.

The honest framing: cross-platform optimises for one team and one budget; native optimises for the ceiling of what the device can do. The price of native is that you build, test, and maintain two apps, so the budget is roughly double a cross-platform build of the same product, and every future change happens twice. We recommend native only when the product genuinely needs that ceiling.

How we work with native iOS and Android apps

For this service we work through both Apple's tools (Xcode and Swift) and Google's tools (Android Studio and Kotlin), so the iOS and Android apps are built on the platform each one belongs to rather than forced through a shared layer. Work is split into the two codebases from the start, with the shared parts of the product (the design, the screens, the API and the business logic on the backend) defined once so the apps stay consistent, and only the native implementation on each side is separate. Stefan works directly with you, remotely, with a reply to your enquiry within 24-48 hours and a smaller or mid-sized delivery running roughly 2-3 weeks, depending on scope. Two rounds of design revision are included.

On the app side, this means native interface components, platform-standard navigation, and direct integration with device features such as the camera, sensors, notifications, offline storage, and background tasks. Any backend service the app needs, such as payments or a data API, is integrated as part of the work, and publishing the finished apps to the App Store and Google Play is prepared and handled with you. Because each app is built for its own platform, the two are tested separately against real devices, and both are yours to keep.

Indicative price

Price for a native app depends on scope: how many screens, how much device integration, how complex the real-time or graphics work is, and the fact that two separate apps are being built. It is also a project you should compare directly against a cross-platform quote before deciding. We do not publish a fixed number here. The estimate comes from the calculator or from a conversation, and payment is 50% in advance to start and the remaining 50% on delivery, on the same terms as every other package, with no instalments.
