Netofficials, an India-based software development company, builds Flutter and React Native apps deployed to both the Google Play Store and the Apple App Store, suited to founders and product managers who need full iOS and Android coverage from a single build.
Cross-platform app development is the practice of writing a single shared codebase compiled and deployed to both the Apple App Store, Apple's distribution platform for iOS apps, and the Google Play Store, Google's distribution platform for Android apps. Netofficials, an India-based software development company, builds these apps using Flutter app development and React Native app development, delivering full iOS and Android coverage without commissioning two separate native builds.
Flutter, Google's open-source UI toolkit, compiles Dart code directly to native ARM machine code, producing high-fidelity interfaces on both platforms from a single source. React Native, Meta's open-source framework, renders native UI components from a JavaScript codebase on both iOS and Android. Both frameworks support device hardware access including camera, GPS, push notifications and biometric authentication through platform plugins. Shared logic covers business rules, data handling, authentication and navigation; platform-specific code is written only where device APIs require it.
Cross-platform development suits consumer apps, MVP development, and B2B mobile tools where feature parity across iOS and Android matters more than platform-exclusive capabilities. It is not suited to apps requiring deep augmented reality, virtual reality or NFC hardware integration exclusive to one platform. Netofficials identifies those constraints during project scoping so buyers can decide before work begins.
Netofficials manages the full delivery cycle: UI/UX design, codebase development, integration with third-party APIs and backend services, quality assurance across both platforms, and app store submission. The client receives two published app listings, documented source code and a handover pack. Cost and timeline depend on the number of screens, user roles, third-party integrations, backend complexity and compliance requirements.
What We Deliver
Netofficials prepares and submits separate listings to the Google Play Store and the Apple App Store from a single shared codebase. Submission work covers store metadata, screenshots, content ratings and platform compliance checks. Buyers receive two approved, downloadable app listings without managing two independent release pipelines.
UI/UX design, the process of designing user interfaces and experiences, is scoped before development begins. Wireframes and a component library are agreed for both iOS and Android screen sizes. Flutter's widget layer or React Native's component model then implements that design, keeping visual language and navigation consistent across platforms without maintaining two separate design files.
Both Flutter, Google's open-source UI toolkit, and React Native, Meta's open-source framework, expose device capabilities through platform channels and community packages. Delivered integrations include camera, GPS, push notifications and biometric authentication. Buyers building field-service, on-demand or consumer apps receive these integrations as tested, production-ready modules, not proof-of-concept wrappers.
Netofficials documents the choice between Flutter and React Native before a line of code is written. Flutter compiles Dart, its programming language, to native ARM machine code and owns its rendering layer. React Native renders native UI components from a JavaScript codebase. The written recommendation covers UI complexity, third-party integration needs and long-term maintainability so your team understands the rationale.
At project close, the full repository is transferred to the client: source code, assets, environment configuration, third-party licences and build scripts. Netofficials retains no ownership over the codebase or intellectual property. The repository is structured so an internal team, a different agency or a continuing Netofficials support arrangement can all pick it up without rework.
Apple and Google release major OS updates on annual cycles that can break existing app behaviour or violate updated store policies. Netofficials provides post-launch support covering iOS and Android version compatibility, Flutter or React Native framework upgrades and store policy changes. Support scope, response times and duration are defined in writing before the engagement starts.
How We Deliver
Netofficials runs a structured discovery session to document user roles, target OS versions, third-party APIs, and backend dependencies. Your product manager or CTO reviews and approves a written scope document before design begins. This document governs feature scope, platform constraints, and acceptance criteria throughout the project.
Designers build one adaptive design system that respects iOS Human Interface Guidelines and Android Material Design conventions simultaneously. You receive annotated wireframes followed by high-fidelity mockups for sign-off. Interaction patterns, typography, and component states are confirmed in writing before a single line of code is written.
Engineers write a shared codebase in Flutter, Google's open-source UI toolkit using Dart, or React Native, Meta's open-source framework using JavaScript, based on the framework agreed at scoping. Camera, GPS, push notifications, and biometric authentication are integrated via platform plugins. You attend sprint reviews to give feedback before features are finalised.
The QA team tests on physical Android and iOS handsets across multiple OS versions, not emulators alone. Test runs cover device API behaviour, offline states, performance under low memory, and OS-specific rendering differences. You receive a structured test report listing each scenario, its result, and any resolved defects before submission.
Netofficials prepares two separate app listings, one for the Google Play Store and one for the Apple App Store, including metadata, screenshots, and compliance documentation. The team manages the submission process and responds to any store review feedback. You receive confirmation of live status on both platforms at project close.

Industry Applications
Netofficials builds a single Flutter or React Native codebase covering product browsing, cart management, payment gateway integration and push notification campaigns, published to both Google Play Store and Apple App Store from one submission pipeline.
Field teams and drivers use a cross-platform app for real-time GPS tracking, job assignment, proof-of-delivery photo capture via device camera APIs and offline form submission when connectivity is unavailable.
Patient-facing apps built on Flutter handle appointment scheduling, practitioner messaging, document upload and biometric authentication, reaching users on both iOS and Android without maintaining two separate native codebases.
A single React Native or Flutter build delivers video course playback, learner progress tracking, quiz modules and push notification reminders to students on any iOS or Android device through one shared codebase.
Cost & Timeline
Cost depends on the scope factors listed below, not on a fixed price list. Timeline is shaped by design complexity, integration availability and app store review cycles. Netofficials provides a scoped estimate after reviewing a short project brief, so you know what to budget before committing.
Get a scoped estimateEach additional screen requires design, build and test cycles. Multiple user roles, such as admin, customer and driver, multiply that effort. Reducing scope to core flows for an MVP lowers both cost and timeline.
Connecting to payment gateways, mapping services, CRMs or analytics platforms adds integration and testing work. Well-documented REST APIs reduce effort; legacy or undocumented APIs increase it significantly.
Apps that need real-time sync, offline support or complex business logic require more backend engineering. Using an existing API or a managed backend-as-a-service can reduce the build scope on this layer.
Healthcare, fintech and education apps must meet standards such as HIPAA, PCI-DSS or COPPA. Each compliance requirement adds audit, data-handling and documentation work that extends both cost and timeline.
Custom animations, brand-specific UI components and multiple revision rounds extend the design phase. Providing clear brand guidelines and consolidating feedback into structured rounds keeps the design stage on schedule.
FAQ
Still deciding? Send a short brief and we reply with questions and a scope.
Ask us directly →Flutter, Google's open-source UI toolkit, compiles Dart code directly to native ARM machine code and draws its own widget layer, so it does not depend on the platform's UI toolkit at all. React Native, Meta's open-source framework, bridges JavaScript to genuine native UI components. For business apps, consumer apps and MVP builds, the performance difference from a fully native app is negligible. The gap becomes measurable only in 3D rendering, real-time video processing or continuous high-frequency sensor reads.
Neither framework is universally better; the right choice depends on specific project conditions.
Netofficials reviews both options against your requirements before recommending one. See the dedicated Flutter app development and React Native app development pages for a deeper comparison.
Yes. Both Flutter and React Native access device hardware through platform plugins that wrap the underlying iOS and Android APIs directly. Camera, GPS, accelerometer, push notifications and biometric authentication are all supported by well-maintained, widely adopted plugins. Netofficials assesses each plugin's maintenance status and community activity during technical planning, so your app does not carry a dependency on an abandoned or under-supported package.
Both Flutter and React Native support platform-specific modulesnative Swift or Kotlin code compiled directly into the cross-platform project, for features that require deep hardware or OS access. If a requirement makes this hybrid approach impractical or disproportionately complex, Netofficials will say so clearly during scoping and can discuss a dedicated native iOS or native Android build. Identifying these boundaries before development starts prevents costly rework mid-project.
Yes. Netofficials manages dual store submission as part of the delivery engagement. This covers preparing release builds, configuring Apple signing certificates and provisioning profiles, generating a signed APK or Android App Bundle for Google, writing store listing metadata, and guiding compliance with the review guidelines of both the Apple App Store and the Google Play Store. You retain full ownership of both developer accounts and every submitted asset.
Cost and timeline are shaped by several variables that interact with each other:
Share your feature list with Netofficials for a scoped estimate. Review the engagement models page to understand how pricing is structured.
Intellectual property ownership is defined in the contract signed before work begins. Netofficials structures engagements so that the client receives full ownership of the source code, assets and documentation on final delivery. This includes the Flutter or React Native codebase, design files, API specifications and any custom platform modules written during the project. Review the specific terms with your legal team before signing, as ownership clauses can vary by engagement model.
Netofficials is an India-based software development company and works with clients in the US, UK and Australia, which span significantly different time zones. Delivery is structured around scheduled overlap windows for live calls, asynchronous updates via written progress reports, and shared project tracking tools so clients can review status without waiting for a meeting. Sprint reviews, backlog grooming and milestone sign-offs are scheduled to fall within agreed overlap hours. See the how we work page for process detail.
