Cross-Platform Development
Client Pain Points
What clients come to us with
Companies often turn to a cross-platform development company when they need to reduce duplication between mobile platforms, synchronize releases, or determine how much functionality should be shared between iOS and Android.
A feature may be defined once but implemented, reviewed, and tested separately for iOS and Android. Even relatively small product changes can therefore require parallel work across two backlogs, two delivery pipelines, and two platform-specific implementations.
Functionality available on one platform may be missing or behave differently on the other. Support responses become platform-specific, release planning becomes harder, and product decisions may depend on which version a customer has installed.
When two platform teams progress at different speeds, coordinating a single product release becomes more complex. Features may need to wait for both implementations to be completed and tested before they can be released consistently across platforms.
Staffing and maintaining separate iOS and Android teams can increase hiring needs and create capacity risks, particularly for smaller engineering organizations. A shared-codebase approach can reduce the amount of platform-specific staffing required for products where cross-platform development is technically appropriate.
Teams may be unsure whether hardware access, offline workflows, background processing, complex animations, or third-party SDKs can be handled effectively within a shared architecture. These requirements need to be reviewed before the framework and code-sharing strategy are selected.
Service Overview
Full-Cycle Cross-Platform App Development, From Architecture to Long-Term Support
Our cross-platform application development services can cover the full product lifecycle, including architecture, implementation, testing, store releases, migration, and continued feature development. The scope is defined per project and can range from a new mobile product to consolidating existing iOS and Android applications.
We design and build iOS and Android applications around a shared codebase, with platform-specific modules added where required. The scope can include application architecture, data handling, offline functionality, user interfaces, and integration with existing backend services.
We can review existing iOS and Android repositories, assess dependencies and platform-specific functionality, and define an incremental migration strategy. Selected functionality can be moved to a shared implementation while the existing applications continue to be supported during the transition.
We define which business logic, data handling, UI components, and other functionality can be shared and which parts should remain platform-specific. The decision is based on device requirements, performance expectations, existing engineering skills, integrations, and platform conventions.
Where the shared framework does not provide direct access to a required capability, native or platform-specific modules can be developed for hardware access, background execution, biometrics, proprietary SDKs, and other device-level functionality.
We can prepare builds, support App Store and Google Play submissions, and provide continued engineering as OS versions, frameworks, dependencies, and product requirements evolve.
Problem u0026 solution
The problem
Maintaining separate native applications can duplicate some business logic, testing effort, release coordination, and maintenance work across iOS and Android. As products evolve, functionality may diverge between platforms, making synchronized releases and consistent user experiences harder to maintain.
Solbeg’s approach
We define which parts of the product should be shared and which should remain platform-specific. Business logic, data handling, UI components, navigation, and other functionality can be shared where technically appropriate, while hardware access and platform-specific behavior remain in native modules. Testing covers both platforms throughout development so differences can be identified before release. Our cross-platform development services can also include coordinated build, release, and post-launch support for both platforms.
Use Cases
When to Choose Cross-Platform Mobile App Development
Companies request cross-platform mobile app development services in a range of situations.
Maintaining separate platform-specific teams may be difficult to justify when the mobile product has a limited feature scope or release cadence. A shared-codebase approach can reduce duplicated engineering and maintenance effort where the product requirements support it.
A contract, campaign, partnership, or product launch may require iOS and Android versions to be available within the same release window. Cross-platform development can simplify coordination when most functionality is shared.
Features may appear on one platform significantly earlier than on the other, creating differences in user experience and support. Consolidating more functionality into a shared implementation can help improve feature parity.
Field service, logistics, warehouse, retail, and other internal applications can be good candidates when most complexity lies in shared workflows and business logic and platform-specific functionality is relatively limited.
A company may need working applications on both mobile platforms to test demand before investing in deeper platform-specific optimization. Cross-platform development can provide a practical way to validate the product with a real audience.
An internal team may no longer have the capacity to maintain two independent native stacks while the product still needs ongoing support and development.
Content, booking, account management, transactional, and similar applications often rely heavily on server-side data and shared business workflows. These products may be good candidates for a shared mobile implementation when platform-specific requirements are limited.
Detailed Scope of Work
What's Included in Cross-Platform App Development
A cross-platform application development project can include the work streams below. The exact composition depends on the product, existing systems, selected framework, and agreed delivery scope.
Shared-layer engineering
The shared layer can include architecture, navigation, state management, business logic, offline and synchronization behavior, error handling, and local storage where these elements can be reused across iOS and Android.
Per-system module development
Platform-specific or native modules can be developed for functionality that requires direct access to sensors, biometrics, background tasks, push notifications, proprietary SDKs, or other OS-level capabilities.
Interface implementation
Screens can be implemented using the agreed design system and adapted to the navigation conventions, screen sizes, typography, accessibility settings, and interaction patterns of each platform.
API and data layer integration
The work can include connection to backend services, API contract review, authentication, caching, error handling, synchronization, and request management for unstable or intermittent network conditions.
QA
Testing can cover functionality, integrations, regression scenarios, supported OS versions, and relevant device configurations. Physical devices, simulators, emulators, and device-cloud coverage can be used according to the project’s test strategy.
Release engineering
Release work can include build pipelines, code signing, distribution builds for testers and reviewers, App Store and Google Play submissions, and crash or performance monitoring setup.
Maintenance
After launch, work can include compatibility updates for new OS and framework versions, dependency upgrades, defect resolution, performance improvements, and incremental feature development.
Why Solbeg
Why Work with Solbeg on Cross-Platform Development
Solbeg combines cross-platform and native mobile expertise to deliver applications that balance development efficiency with platform-specific requirements. Our teams cover framework selection, UI/UX design, engineering, QA, integrations, and ongoing development within a single delivery scope.
The framework choice is not decided by what we happen to staff
Solbeg works with both Flutter and React Native. This allows framework selection to be based on interface requirements, existing engineering skills, product architecture, performance expectations, and the third-party SDKs or platform capabilities the product needs rather than on a single available technology.
Native skills stay in-house
Swift, Objective-C, and Kotlin are also part of Solbeg’s mobile engineering capabilities. When platform-specific functionality or native integrations are required, that work can be handled within the same technology partnership without introducing a separate vendor.
QA is a separate delivery stage
QA is handled by dedicated quality specialists and can run alongside development rather than being absorbed entirely into implementation work. Testing across devices, OS versions, integrations, and user flows helps identify platform-specific and parity issues before production release.
Design and engineering under one scope
Requirements analysis, prototyping, UI/UX design, engineering, and testing can be coordinated within the same engagement. This allows interface decisions to be reviewed against technical constraints before they become more expensive to revise later in delivery.
An established delivery record
Solbeg has completed more than 50 mobile projects and operates delivery teams across Poland, India, Uruguay, and the United States. This experience provides practical context for mobile products that need cross-platform engineering, integrations, testing, release support, and continued development.
Comparison
Cross-Platform Development Approaches
Solbeg has engineering capabilities in both Flutter and React Native, so the recommendation can be based on the product rather than a single available framework. Three factors are particularly useful when comparing the options: interface requirements, the client’s existing engineering stack, and the SDKs or platform capabilities the product needs.
Flutter
Flutter can be well suited to products that require a highly consistent custom interface across platforms, complex visual layouts, or a shared rendering approach for iOS and Android.
React Native
React Native can be a strong option for organizations with JavaScript, TypeScript, or React expertise and for products whose mobile applications share concepts, validation rules, API models, or engineering practices with an existing web product.
Shared rules, separate interfaces
This approach can suit products that need distinctly native interfaces on iOS and Android while sharing domain logic, networking, storage, synchronization rules, or access control underneath.
Flutter
Teams may need Dart expertise, while unsupported platform capabilities, proprietary SDKs, or specialized hardware integrations can still require native development.
React Native
Highly customized interfaces, platform-specific SDKs, and specialized device features may require additional native work. Third-party package quality and long-term maintenance should also be considered during architecture planning.
Shared rules, separate interfaces
Two platform-specific interface layers still need to be developed, tested, and maintained, and the team needs native engineering expertise across both ecosystems.
Flutter
A large share of UI and business logic can be shared across platforms, while framework, dependency, and OS compatibility updates remain part of ongoing maintenance.
React Native
Existing React or JavaScript expertise can reduce onboarding effort, while a substantial part of application logic and UI implementation can be shared across platforms.
Shared rules, separate interfaces
The model can reduce duplication in shared business logic while preserving fully native interfaces and platform-specific interaction patterns.
Process
How Solbeg Delivers Cross-Platform Applications
A typical engagement with a cross-platform app development company can follow five stages, with the depth and sequence adapted to the project, existing product, and delivery model.
-
Discovery
We collect functional requirements, integration points, supported devices, platform constraints, and relevant business requirements. If an existing product is involved, we can also review repositories, dependencies, analytics, and known defects.
-
Architecture and scope definition
We define what should remain shared and what should be platform-specific, establish the initial release scope, select the technical approach, and prepare an estimate based on that scope.
-
Team setup and onboarding
Engineers receive access to repositories, environments, design files, backend documentation, and collaboration tools. Development, build, testing, and communication processes are prepared before implementation begins.
-
Iterative delivery and QA
Development can proceed incrementally, with installable iOS and Android builds made available for review as the product evolves. Testing can run throughout delivery so parity, integration, and platform-specific issues are identified before release.
-
Release and continued work
We can prepare store submissions, support the review process, monitor stability after launch, and continue development based on product analytics, technical findings, and the client’s roadmap.
FAQ
Cross-Platform Development FAQ
We consider the interface requirements, the engineering technologies already used by the client’s team, performance expectations, platform-specific functionality, and third-party SDKs that must be integrated. The recommendation can be documented during scope definition so the client can review the technical trade-offs before implementation begins.
Performance depends on the application’s workload, UI complexity, framework, integrations, and platform-specific requirements. Many business applications can achieve suitable performance with a cross-platform architecture, while graphics-intensive, latency-sensitive, hardware-heavy, or highly platform-specific functionality may benefit from native implementation.
Yes. Depending on the existing architecture, consolidation can be planned incrementally rather than requiring a single full rewrite. We can identify which components depend heavily on platform APIs and which business or data-layer functionality can be moved to a shared implementation. The migration approach can be designed to maintain ongoing product support during the transition.
These capabilities may be supported through framework libraries or implemented through native modules where direct platform access is required. Proprietary SDKs, specialized hardware, or functionality not covered by the selected framework can be estimated separately during architecture and scope definition.
Yes, when that is part of the design requirements. Navigation patterns, system controls, typography, gestures, and other conventions differ between iOS and Android and can be adapted accordingly. If the product requires an intentionally identical appearance across both platforms, that can also be defined during product and interface design.
Framework longevity and ecosystem stability are factors considered during architecture planning. Solbeg can reduce dependency risk by separating shared business logic, platform-specific integrations, and framework-dependent components where the selected architecture supports this separation. Framework and dependency maintenance should also be included in the product’s long-term technical roadmap.
Compare how each vendor defines the boundary between shared and platform-specific code, how framework and OS upgrades are handled after launch, what device and OS coverage testing includes, how native integrations are delivered, and who manages store submissions. It is also useful to understand the reasoning behind previous architecture decisions rather than comparing framework lists alone. Support, ownership, and maintenance responsibilities should be clarified before the engagement begins.
