Native or cross-platform? Mobile App Developers who can make that call

Anyone can set up a React Native or Flutter starter and launch on both app stores over a weekend. Cortance screens mobile developers for the harder call: whether that weekend project should stay cross-platform or move to native Swift and Kotlin. Getting that choice wrong often turns a six-week MVP into a six-month rebuild.

Native iOS, native Android, or one shared codebase

Cortance's mobile network covers native iOS in Swift, SwiftUI and Objective-C; native Android in Kotlin, Java and Jetpack Compose; and cross-platform delivery in React Native and Flutter. Engineers build on MVVM and Clean Architecture, set up REST and GraphQL APIs, and integrate Firebase, AWS and Google Cloud. Our developers handle the parts that separate a demo from a shipped product: secure payments, push notifications, offline sync, analytics, and CI/CD pipelines that get an app through App Store and Google Play review. Developers are screened for production experience in consumer apps, fintech and banking, e-commerce and marketplace apps, on-demand services and enterprise mobility.

That range shows up in what our engineers have shipped. Dmytro K., a senior mobile developer working across both iOS and Android, built the mobile client for Solive, a social and dating platform, owning user discovery, matching, and live video and audio communication end to end. Oleh K., a React Native developer, shipped MOVADEX as a cross-platform build and later published Tanaroom, an AI-assisted language-learning app, to the App Store, handling daily vocabulary practice and text-to-vocabulary extraction packed into five-to-ten-minute sessions. Dmitriy L., a senior Android developer, built Cashli, a native app that handles task-based payouts across multiple bank integrations.

AI-assisted code review helps most on crash-prone paths in mobile code. A review pass can flag a force-unwrapped optional, a missing null check or a retain cycle before it becomes a crash report. It does not know how the app behaves on an old Android device or why a build keeps failing App Store review, so a senior mobile engineer still owns the release.

Building the team as you need

Most engagements land on one of three shapes:

1. A dedicated mobile team taking a product from architecture through App Store and Google Play release.
2. A single senior engineer or mobile tech lead to architect the solution and mentor an in-house team.
3. Staff augmentation to clear a specific release without slowing down the rest of the roadmap.

Not sure whether cross-platform is the right fit?

Recent architecture updates in React Native and Flutter have closed much of the old performance gap with native. AI features shift the calculus further: React Native's JavaScript-first SDKs tend to suit cloud-based AI features, while Flutter's rendering control suits on-device inference. Camera-heavy, AR-heavy or App-Store-revenue-first products still justify the native premium.
