Best Cross-Platform App Development Service in Bangladesh

Two separate native builds cost twice the time and twice the budget. Framecipher builds cross-platform apps in Flutter or React Native, one codebase that runs on both Android and iOS, for startups and businesses in Dhaka, and for clients across the US, UK, Australia, Canada, and UAE who need to reach both audiences without funding two parallel development teams.

“Cross-platform doesn't mean identical. It means writing the logic once and still respecting that an Android user and an iOS user expect different things from the same app.”

Scope of work

What we deliver

A practical breakdown of the strategy, production, and technical work included in this service.

01

FRAMEWORK STRATEGY & ARCHITECTURE

Before any code gets written, we decide which framework fits your app and plan around what shared code can and can't cover. Guessing at framework fit after development has started is how a project ends up rebuilding parts of itself halfway through.

  • Framework Selection: Flutter or React Native, chosen based on your app's specific performance and integration needs.
  • Requirements & Feature Planning: Deciding what's core to launch versus what waits for a later release.
  • Shared vs. Native Module Planning: Identifying where shared code works cleanly and where a platform-specific module is the better call.
  • Technical Architecture Planning: Data flow, state management, and API structure, mapped out before development starts.
02

UI/UX DESIGN FOR BOTH PLATFORMS

One design system, built to still feel native on both Android's Material Design and Apple's Human Interface Guidelines. An interface that looks identical on both platforms usually means it feels wrong on at least one of them. CROSS-PLATFORM DEVELOPMENT (FLUTTER / REACT NATIVE) This is where shared code becomes a working app on two operating systems at once. Most of the app ships from one codebase. The parts that need to be different, still are. TESTING, DEPLOYMENT & DUAL STORE LAUNCH Every build gets tested on both platforms independently, shared code doesn't mean shared results. Passing on one platform doesn't mean passing on both, we test each one on its own terms.

  • Platform-Aware Interface Design: Shared visual language with adjustments where Android and iOS conventions genuinely diverge.
  • User Flow Mapping: Navigation and key actions structured so they make sense on both platforms, not just one.
  • Adaptive Layouts: Consistent behavior across phone and tablet screen sizes on either OS.
  • Prototype & Usability Testing: Testing the flow on real devices from both ecosystems before development locks it in.
  • Flutter or React Native Development: Clean, maintainable shared code, built around the framework that actually fits your app.
  • Native Module Integration: Platform-specific code where the framework's shared layer can't reach a feature you need.
  • API & Backend Integration: Connecting to your existing backend, third-party services, or a new API built for the app.
  • Push Notification Setup: Configured for both Firebase Cloud Messaging and Apple Push Notification service, correctly, on each side.
  • Cross-Device Testing: Real Android and iOS devices, across OS versions, not just one reference phone per platform.
  • Performance & Load Testing: Confirming the app performs well under real conditions on each operating system.
  • Dual Store Submission: Google Play and App Store submissions handled together, each to its own current requirements.
  • Crash Reporting & Analytics Setup: Visibility into how the app performs post-launch on both platforms, not just one.
03

ONGOING SUPPORT & MAINTENANCE

Two platforms, two sets of OS updates, one app that needs to keep working through both. Available as a separate ongoing service - see our [App Maintenance & Support] page for full details, since this isn't included by default in a development engagement.

  • OS Compatibility Updates: Keeping the app current as Android and iOS both roll out new versions, on their own schedules.
  • Bug Fixes & Performance Monitoring: Issues addressed as they surface, on whichever platform they show up.
  • Framework Version Updates: Keeping Flutter or React Native itself current as the framework evolves.
  • Feature Updates: New functionality built once, deployed to both platforms together.

The business case

Why this matters

The appeal of cross-platform is speed and cost. Losing either one usually means the framework was chosen for the wrong reasons.

Reaching Both Audiences Without Doubling the Budget

Two native builds mean two teams, two timelines, two budgets. One well-built cross-platform app reaches both user bases from a single, coordinated development effort.

Shared Code Still Needs Platform Judgment

Not every feature behaves identically across Android and iOS. Knowing where to insert a native module, instead of forcing a shared-code workaround, is what keeps the app feeling right on both.

Faster Path to Market

One codebase generally means a shorter timeline than building and maintaining two separate native apps in parallel, a real advantage when speed to launch matters.

One App, Consistent Behavior

Bugs fixed once apply to both platforms. Features shipped once reach both platforms together. That consistency is the practical payoff of doing this properly.

Why Frame Cipher

Built for accountable delivery

Strategy & Architecture

Your app's requirements mapped out, with an honest recommendation on Flutter versus React Native.

Platform-Aware UI/UX

Interfaces designed to feel native on both Android and iOS, not a compromise that fits neither.

Cross-Platform Development

Shared code where it works cleanly, native modules where it doesn't, built by people who know the difference.

Dual-Platform Testing

Real devices, both operating systems, tested independently before either submission goes out.

Dual Store Deployment

Google Play and App Store submissions, each handled to its own current requirements.

Transparent Process

Approval checkpoints at every stage, nothing built without you seeing it first.

Delivery process

A clear path from brief to result

Each stage has a defined outcome and review point, so you always know what is happening next.

  1. Step 01

    Initial Consultation

    We talk through your app idea, target users, and which framework actually fits what you're building.

  2. Step 02

    Strategy & Architecture Planning

    Technical architecture, shared-vs-native module decisions, and scope, defined before development starts.

  3. Step 03

    Design & Development

    Platform-aware UI/UX first, with checkpoints along the way, then Flutter or React Native development.

  4. Step 04

    Testing & Quality Assurance

    Independent testing on real Android and iOS devices, before either store submission.

  5. Step 05

    Launch & Dual Store Deployment

    We handle both submissions, confirm the live app works on each platform, and walk you through what's next.

Pricing guide

Clear scope before commitment

Cross-platform pricing depends on feature complexity, how much native module work is needed, and backend requirements, generally less than building two separate native apps, but not identical to a single-platform build either.

Coverage

Dhaka-based, worldwide delivery

Framecipher is based in Dhaka and builds cross-platform apps for businesses across Bangladesh and clients in the UAE, US, UK, Australia, and Canada, 20+ countries so far. Different regions bring different app store requirements and different device habits, and the build accounts for that instead of assuming one market's patterns everywhere.

Bangladesh's mobile market leans heavily on Android, with a smaller but present iOS user base, a mix that makes cross-platform a genuinely practical fit for local businesses trying to reach both without splitting budget across two full native builds.

Schedule

Timeline & duration

Most cross-platform builds run 7 to 20+ weeks, shaped by feature complexity, native module needs, and backend work. A simple MVP moves the fastest. Heavy native integration or enterprise-scale requirements push the timeline out.

Dual store submission adds its own timing considerations, Google Play and Apple review on different schedules, and planning around both matters if you're working toward a fixed launch date.

Accountability

Review & approval

Every stage architecture, design, development, goes through your review before we move forward. Nothing reaches either store submission without your sign-off.

Store approval isn't something we control, that decision belongs to Google and Apple separately. What we guarantee is a build submitted correctly to both platforms' current guidelines, with support if review feedback comes back on either side.

FAQ

Common questions, answered

Should I choose Flutter or React Native?+

It depends on your app's needs. Flutter tends to offer more consistent UI rendering across platforms; React Native has a larger ecosystem of existing libraries and works well if your team already knows JavaScript. We'll walk through the tradeoffs based on your specific project.

Will a cross-platform app feel as good as two separate native apps?+

When built properly, yes, for most use cases. The difference shows up in graphics-intensive or deeply platform-specific features, where native modules fill the gap rather than forcing a compromise.

Is cross-platform actually cheaper than building native apps for both platforms?+

Generally, yes, one codebase for shared logic costs less than building and maintaining two entirely separate native apps, though the exact savings depend on how much native module work your app ends up needing.

Do you handle submission to both Google Play and the App Store?+

Yes, both submissions are part of our process, each prepared to that platform's own current requirements rather than treated as a single combined step.

Do you work with clients outside Bangladesh?+

We do, alongside Bangladeshi businesses, we build cross-platform apps for clients in the US, UK, Australia, Canada, and UAE.
