What is the difference between Native and Cross-Platform development, and which should I choose?

Native development uses platform-specific languages (Swift for iOS, Kotlin for Android), while cross-platform development utilizes shared codebases like Flutter. As a legacy mobile app modernization design consultancy, we analyze your feature complexity and team structure to choose the model that maximizes code reuse while maintaining premium performance.

What happens after the app goes live? Do you offer ongoing maintenance?

Yes, running an enterprise app requires continuous engineering to handle annual OS updates, SDK changes, and store policy compliance. Partnering with a legacy mobile app modernization development firm provides you with proactive platform operations, SLA-backed crash monitoring, and long-term release governance.

Can you build applications that function without an active internet connection?

Yes, we engineer applications with local data caching, offline workflows, and robust data synchronization protocols. This architectural approach ensures users retain access to critical enterprise features during network disruptions, securing long-term legacy app modernization benefits like consistent channel availability.

Are your mobile apps compliant with accessibility standards (ADA / WCAG)?

Absolute compliance is integrated directly into our development lifecycle through automated cloud device farms and rigorous manual evaluation. Prioritizing accessibility standards during a legacy mobile app modernization redesign broadens your market reach, protects user retention, and eliminates regulatory compliance risks.

Native Mobile App Development Services

Native iOS and Android engineering

Our native iOS and Android teams bring 15 years of platform-specific engineering experience. They have built native products across fintech, entertainment, and enterprise.

Let's work together

Native development, tailored to your platform

Whether you're building for one platform or both, our native development teams bring platform-specific expertise to every project. Dedicated Android (Kotlin) and iOS (Swift) teams can build both apps in parallel.

Android app development

We build native apps for Android with Kotlin and Jetpack Compose to reach 72% of the global mobile market. Material 3 components keep gestures, TalkBack, and dark mode working as users expect. Explore our Android app development services in more detail.

iOS app development

We build apps for iPhone and iPad with Swift and SwiftUI, using UIKit where needed. SwiftUI components keep Dynamic Type, VoiceOver, and dark mode working as users expect. Skyscanner, TUI, BNP Paribas, and Herbalife have trusted our iOS app development team for over a decade.

Should you choose native or cross-platform?

We build native, Flutter, and Kotlin Multiplatform apps, so our recommendation isn't tied to one technology. Here's how we usually decide.

Go native when

• Your app depends on hardware
• You need AR or on-device machine learning
• You need extensions: watch apps, widgets, CarPlay, Android Automotive
• You're building an SDK that other apps will embed
• You already have a native codebase to extend

Go cross-platform when

• Both platforms get the same feature set
• The UI is mostly standard screens on top of an API
• Time to market and budget are the main constraints

Consider KMP when

• You want native UI on both platforms but one shared layer for business logic, networking, and data.
• Kotlin Multiplatform shares that code while each app keeps a fully native UI, so you get less duplicated logic.

Our Development Process

Scoping & estimate

We learn your goals and recommend an approach: native, cross-platform or KMP.

You get a timeline and a cost range.

Discovery → Short Spec

A two-day joint workshop kicks off a short phase that maps features, integrations and assumptions.

The output, a concise Short Spec, becomes part of the contract and locks scope and budget.

Specification → Long Spec

Your product owner turns the Short Spec into user stories, acceptance criteria and edge cases for each platform.

It's versioned like code: if it isn't in the spec, it doesn't get built.

Delivery

A dedicated pod builds in a continuous flow, and you get a working build every two weeks.

Developers plan each task, direct AI agents and review every change before it passes six quality gates.

Release

We handle App Store and Google Play submission and review feedback.

Phased rollout on both stores lets you see real-world data before the app reaches 100% of users.

Handover & support

You own the code, the full specification and the architecture decisions.

Stay with us for updates and new features, or take it in-house with nothing missing.

Frequently Asked Questions

Haven't you found the answers?

Talk to us

Why should I choose native development over React Native or Flutter?

Going native is the right call when your product depends on hardware access, AR, on-device ML, or platform extensions like watch apps or CarPlay. The same goes for the newest OS features. If your app is mostly standard screens over an API, Flutter or React Native will likely get you to market faster and for less. In that case, we'll tell you so.

How long does it take from idea to App Store launch?

On average, a native app MVP takes around 3 months to develop. A simple app typically takes 3 to 4 months from start to launch, a more complex one 6 to 7 months. A multifunctional, feature-rich product can take up to a year, depending on scope, features, and team size.

What's the cost of native app development?

Costs vary based on app complexity, features, and team size, typically ranging from $50,000 to $300,000+. We provide a detailed estimate after understanding your project scope during the initial scoping phase.

Can you take over an existing app or migrate it to native?

Yes. For an existing native app, we start with a code and architecture audit, then agree on a stabilization plan before adding new features. For a Flutter or React Native app, we start with the specification: every flow, rule, and edge case is written down and agreed with you. The new native apps are then built from that spec, so feature parity can be checked point by point.
