Native builds separate apps for iOS (Swift) and Android (Kotlin)—maximum performance and platform-specific feel, but nearly double the cost and maintenance. Cross-platform builds one app that runs on both—significantly faster to develop, easier to maintain, and 90-95% of native performance for most use cases. We recommend cross-platform unless you need cutting-edge gaming graphics, heavy AR/VR, or platform-exclusive features that frameworks can’t access.
Cross-Platform App Development
One app, every platform. Built by Nepal’s most reliable team. We create apps that run on both iOS and Android from a single codebase—saving you time, money, and the headache of managing two separate projects.

Cross-Platform App Development
Get a QuoteReach more users, spend less budget, and launch faster without sacrificing quality.
At Webtech Nepal, we believe most businesses don’t need to build separate apps for iPhone and Android. They need one solid app that works well everywhere, launched quickly enough to matter, and maintained affordably over time. Cross-platform development lets us write code once and deploy to both platforms—cutting development time nearly in half while keeping performance and feel close to native. We use Flutter and React Native, the two leading frameworks trusted by companies from Google to Facebook to Shopify. The result is an app that looks right at home on any device, loads fast, and doesn’t drain batteries—without the cost and complexity of maintaining two codebases.
Whether you’re a startup validating an idea, a business needing internal tools on every employee’s phone, or a brand reaching customers across Nepal’s diverse device landscape, we can help. We focus on what matters: does the app solve the user’s problem? Does it work on the budget phones that dominate our market? Does it feel responsive and polished? We don’t chase perfect native parity for features users never notice. We build apps that ship fast, work reliably, and leave budget for marketing and iteration.
We build cross-platform apps that help Nepali businesses reach iOS and Android users quickly, manage one codebase instead of two, and iterate based on real feedback rather than sunk investment. Here’s what we do:
Flutter App Development
Apps built with Google’s framework that compiles to native machine code. We create smooth animations, consistent UI across platforms, and high performance—ideal for apps with custom designs, complex interfaces, or when visual polish is critical. Flutter’s single codebase covers mobile, web, and desktop if you need to expand later.
React Native App Development
Apps built with Facebook’s framework using JavaScript and React. We leverage massive community support, extensive third-party libraries, and familiar web development patterns—ideal when your team already knows JavaScript or when you need rapid integration with existing web services.
Business & Productivity Apps
Internal tools that run on every employee’s phone. We build attendance tracking, task management, expense reporting, document access, and team communication—giving your workforce mobility without buying everyone the same device or maintaining separate apps.
E-Commerce & Shopping Apps
Stores that reach buyers on every platform. Product catalogs, cart management, secure checkout, order tracking, and push notifications for deals—all built once and deployed everywhere, maximizing your market reach without doubling development costs.
On-Demand Service Apps
Platforms connecting customers with immediate services. Real-time tracking, matching algorithms, payment handling, and rating systems—for delivery, transportation, home repairs, or any business where speed and location matter across both iOS and Android.
Social & Community Apps
Connection platforms that grow through network effects. Feeds, messaging, media sharing, notifications, and moderation—built for both platforms so no potential user is excluded based on their phone choice.
Booking & Appointment Apps
Scheduling tools for clinics, salons, consultants, and rentals. Calendar management, instant confirmations, reminders, and payments—reaching customers regardless of whether they carry iPhones or budget Androids.
Education & Learning Apps
Mobile classrooms accessible to all students. Video lessons, quizzes, progress tracking, and offline content—ensuring learners on any device can access education, critical in Nepal’s diverse economic landscape.
Fitness & Lifestyle Apps
Health and habit tools for broad audiences. Workout plans, activity tracking, nutrition logging, and progress visualization—integrated with phone sensors and built to motivate users across both platforms.
Content & Media Apps
Publishing platforms for news, entertainment, or branded content. Article reading, video streaming, offline saving, and personalized recommendations—delivered consistently whether users prefer iOS or Android.
App Migration to Cross-Platform
Moving existing native apps to a unified codebase. We audit your current apps, plan feature parity, rebuild with Flutter or React Native, and manage the transition—reducing future maintenance burden while preserving user experience.
Cross-Platform Maintenance & Updates
Ongoing care for one codebase serving two platforms. Single updates reach all users simultaneously, bug fixes apply everywhere, and new features roll out consistently—eliminating the version drift that plagues separate native apps.

Frequently Asked Questions
For most business apps, yes. Flutter compiles to native machine code; React Native uses native UI components. Users rarely notice the difference in everyday apps—shopping, booking, social, content. Where cross-platform can lag: complex animations, heavy graphics processing, or deep hardware integration. We assess your specific needs honestly and recommend native if cross-platform truly won’t deliver.
Typically 40–60% on initial development and 50–70% on ongoing maintenance. One codebase means one team, one set of bug fixes, one update cycle. When you add a feature, every user gets it simultaneously. When you fix a bug, it’s fixed everywhere. Over a few years, maintenance savings often exceed initial development costs.
A focused app with core features typically takes 8–14 weeks. Complex apps with real-time features, custom backends, or extensive integrations take 14–20 weeks. Compared to native, you’re usually looking at similar timelines for one platform—but you’re getting both iOS and Android simultaneously, effectively halving your time-to-market.
Yes, with intentional design. We adapt navigation patterns, buttons, typography, and gestures to match each platform’s conventions while maintaining your brand identity. Flutter’s widget system and React Native’s native component rendering both support platform-aware styling. Users feel at home whether they’re on iOS or Android.
