Choosing a framework on hype
Picking Flutter or React Native because of a blog post, rather than your features and your team's skills, often leads to workarounds later.

Cross-platform app development services, starting with the right approach for your app
Before any code, we help you decide between one shared codebase and two native apps. When cross-platform fits, we build it in Flutter and ship to both stores from the same source.
What is Cross-Platform App Development?
Cross-platform app development services deliver one mobile app for both Android and iOS from a largely shared codebase, instead of writing and maintaining two separate native apps. The main frameworks are Flutter, which uses Dart and draws its own interface, and React Native, which uses JavaScript or TypeScript and renders native platform components. The right choice depends on your features, your team and how closely the app must match each platform's native behavior.
Building separate Android and iOS apps doubles much of the work: two codebases, two sets of bugs, two release trains and features that drift apart. Cross-platform frameworks remove most of that duplication, but they are not free. Some features still need platform-specific code, framework upgrades become a dependency, and the wrong choice can be expensive to reverse. The decision deserves a few hours of analysis before months of development.
What the cross-platform decision really involves
Features that need native code
Background processing, Bluetooth, some payment SDKs and newer OS features may require platform-specific code alongside the shared app.
Platform expectations
Android and iOS users expect different navigation patterns, back behavior and system dialogs. A shared codebase still has to respect both.
Long-term maintenance
Framework, plugin and OS updates arrive on their own schedules. A cross-platform app needs someone keeping all three in step.
Our Cross-Platform App Development service
Approach assessment
A written recommendation on Flutter, React Native or native apps based on your feature list, hardware needs, existing code and the team who will maintain it.
Flutter development
Our primary cross-platform stack: a single Flutter codebase compiled to native Android and iOS apps, covered in detail on our Flutter page.
Platform-specific integration
Native Kotlin and Swift code where a feature cannot be done in the shared layer, connected to the app through platform channels.
Adaptive design for both platforms
Shared brand and layouts with platform-appropriate navigation, typography, dialogs and gestures so the app feels right on each phone.
Dual-store release
Coordinated Google Play and App Store submissions, test tracks on both platforms and synchronized versioning.
Migration from two native apps
Assessment and phased consolidation of separate Android and iOS apps into one codebase, where the economics make sense.
Included capabilities
- One codebase for Android and iOS
- Shared business logic and API layer
- Platform-adaptive navigation and dialogs
- Native modules for hardware access
- Offline storage and background sync
- Push notifications on both platforms
- Single CI pipeline for both stores
- Optional web or desktop target from the same code
What Cross-Platform App Development changes for your business
Less duplicated effort
Most features are built and tested once, then shipped to both platforms.
Feature parity
Android and iOS users get the same features in the same release, without one app lagging behind.
One team to manage
A single codebase and release process is simpler to staff, review and hand over.
Native where it counts
Platform-specific code is still available for the few features that need it.
Where it makes the biggest difference
Startup MVPs
One team and one codebase reach both app stores, so early budget goes into testing the idea rather than duplicating it.
Business and internal apps
Order taking, approvals, field reporting and customer portals where consistent features matter more than platform-specific flourishes.
Customer apps for existing businesses
Loyalty, booking or ordering apps that must work identically for Android and iPhone customers.
Consolidating two native apps
Organizations paying to keep separate Android and iOS apps in sync, who want one roadmap and one release process.
Decide first, then build once
The riskiest native features are prototyped before the rest of the app is built on top of them.
Requirements review
Feature list, hardware access, integrations, target audience and expected lifespan of the app.
Approach decision
Cross-platform or native, and which framework, recorded with the reasons so the decision can be revisited.
Proof of risk
Any feature most likely to need native code is prototyped first, before the rest of the app depends on it.
Design
One design system with documented platform differences for Android and iOS.
Build & test
Iterative development with test builds on both platforms and testing on real Android and iOS devices.
Release
Store listings, policy declarations and submissions to Google Play and the App Store.
Maintain
Framework, plugin and OS updates handled together so both platforms stay current.
What it connects to
Cross-Platform App Development
- REST and GraphQL APIs
- Firebase services
- Push notifications (FCM and APNs)
- In-app purchases on both stores
- Maps and location services
- Payment gateways
- Odoo and ERP back ends

| Criterion | Flutter | React Native | Native (Kotlin + Swift) |
|---|---|---|---|
| Language | Dart | JavaScript / TypeScript | Kotlin for Android, Swift for iOS |
| Codebases | One shared | One shared | Two separate |
| How UI is drawn | Own rendering engine and widgets | Native platform components | Native platform components |
| Access to new OS features | Via plugins or platform channels | Via native modules | Immediate |
| Fits teams that know | Dart or general OOP languages | React and JavaScript | Android and iOS separately |
| Best fit | Custom, consistent UI on both platforms | Teams with existing React web code | Platform-heavy or single-platform apps |
Security, quality and scale
Platform secure storage
Credentials stored in the Android Keystore and iOS Keychain through vetted plugins, not in plain local storage.
Dependency vetting
Third-party packages reviewed for maintenance status, licensing and permissions before they are added.
Transport security
HTTPS-only API traffic with token-based authentication and optional certificate pinning.
Release hardening
Obfuscation and debug features disabled in release builds for both platforms.
What working with us looks like
We'll tell you when native wins
We also build native Android and iOS apps, so our advice isn't bent toward one framework.
Flutter as a focused stack
We concentrate on Flutter for cross-platform work rather than spreading across every framework.
Native skills for the edges
When a feature needs Kotlin or Swift, the same team writes it instead of hunting for a plugin.
Back end in the same project
APIs, admin panels and ERP connections can be delivered alongside the app.
What it costs
Fixed-price packages with the scope written down, paid stage by stage. Your project goes live once it's fully paid.

Cross-Platform App Development: questions we hear most
Is a cross-platform app cheaper than two native apps?
Usually, because most features are built and tested once instead of twice. The saving is smaller when an app relies heavily on platform-specific features, since those still need native code for each platform. We estimate both options when it is a close call.
Should we choose Flutter or React Native?
Both are mature choices; the better one depends on your app and team. Flutter suits apps that want a consistent custom interface on both platforms, while React Native can suit teams that already work in React and JavaScript. Digihub builds cross-platform apps primarily in Flutter.
Will a cross-platform app perform as well as a native one?
For most business and consumer apps, users are unlikely to notice a difference when the app is built carefully. Demanding cases such as heavy 3D graphics, complex real-time media or deep OS integration can favor native code.
Can a cross-platform app use the camera, GPS and Bluetooth?
Yes. Common hardware features are available through established plugins, and anything not covered can be written natively in Kotlin or Swift and called from the shared code.
Can the same code also run on the web?
Flutter can also target web and desktop from the same codebase, which works well for internal tools and dashboards. For public, search-indexed websites, a dedicated web build is usually the better choice.
Can we convert our existing native apps to cross-platform?
Yes, but it is effectively a rebuild of the interface, so it only makes sense when maintaining two apps is costing more than the migration. Flutter can also be added to an existing native app screen by screen.
