React Native cross-platform development — iOS and Android from one codebase
Why Cross-Platform

Two native apps cost 2×.
Ours ship for the price of one.

Native iOS and Android development means two separate teams, two separate codebases, two sets of bugs. React Native and Flutter share 95% of the code while delivering a fully native feel on both platforms.

Native: separate iOS + Android teams
One codebase — both stores covered
2× the bugs to fix and maintain
Single fix deployed to iOS and Android
2× the cost, 2× the timeline
Ship both stores in 8–14 weeks
Inconsistent UX across platforms
Shared design system — identical experience
Double the hiring and onboarding
One team, full ownership, no silos

What We Build

Apps that feel built for the phone, not ported to it

Every interaction is designed for thumbs, not cursors. Every feature uses the phone's native capabilities — no browser workarounds.

Cross-Platform iOS & Android

One codebase, two stores — React Native and Flutter apps that feel native on iOS and Android. Shared business logic, platform-specific components where it matters. You ship to both platforms for the price of one.

  • React Native & Expo
  • Flutter for pixel-perfect UIs
  • Shared business logic
  • Platform-specific components

Native Device Integration

Camera, GPS, biometrics, NFC, Bluetooth — we integrate any native capability your app needs. No workarounds, no third-party hacks. Your users expect their phone's features to work in your app.

  • Camera & photo library
  • GPS & maps integration
  • Face ID / Touch ID
  • NFC & Bluetooth

Offline-First Architecture

Apps that work without internet and sync seamlessly when the connection returns. In Bangladesh, where mobile data drops mid-session, offline-first is the difference between users keeping or deleting your app.

  • Local SQLite / MMKV storage
  • Background sync
  • Conflict resolution
  • Push-to-sync architecture

Push Notifications & Re-Engagement

FCM and APNs integration with segmented, scheduled and triggered notification systems. The right message at the right moment brings users back. We build notification infrastructure that makes re-engagement campaigns actually work.

  • Firebase Cloud Messaging
  • APNs integration
  • In-app notifications
  • Deep link handling

App Store Publishing

We handle the entire submission — App Store and Play Store — including screenshots, metadata, privacy policies and review communications. We know what triggers rejection before we submit.

  • App Store (iOS) submission
  • Play Store (Android) submit
  • App review support
  • ASO & keyword strategy

Real-Time & Live Features

Live chat, delivery tracking, collaborative tools — powered by WebSockets and Firebase. Real-time turns a utility app into an experience users can't put down. We've built everything from ride tracking to live auction bidding.

  • WebSocket integration
  • Firebase Realtime DB
  • Live location tracking
  • Collaborative UIs

Our Process

You test on a real device from Week 2.

No surprises at handover. You see the app on your phone every sprint — before a single line of code is finalised.

01

Discovery & User Flows

We map user journeys, define MVP scope, choose platform strategy (RN or Flutter) and establish technical constraints. You get a written kickoff spec within 48 hours.

02

UI/UX Design

Every screen in Figma — reviewed and approved before a single line of code is written. We prototype flows on real devices so you experience the app before we build it.

03

Sprint Development

TestFlight and Play Console builds from Week 2 — you test on your real device throughout development, not just at handover. 2-week sprints with weekly demos.

04

Launch & Monitoring

Store submission, staged rollout, crash monitoring with Sentry and 30 days post-launch support. We watch crash rates and session metrics in the first month — together.

Our Guarantee

Three commitments we put in writing.

Not promises in a sales call. Written into your contract. If we miss them, we fix it at no additional cost.

01

Store approval — handled

We manage every App Store and Play Store submission. If Apple or Google rejects the build, we handle the response and resubmission at zero additional cost. Rejections don't delay your timeline or invoice.

02

iOS + Android. One price.

One codebase, both platforms. What you're quoted covers iOS and Android — not one or the other. 95% shared logic with platform-native UX on both stores. You don't pay twice for the same product.

03

30-day post-launch support

Crash monitoring, bug fixes, store review responses and performance checks for 30 days after go-live — included in the project price. We watch the metrics in the first month with you.

Client Reviews

What clients say after launch

Cross-platform was the right call — we shipped iOS and Android in 14 weeks for what two agencies quoted just for one platform. 4.6 stars on both stores within a month.

Tanvir Hossain
Founder, AmarSeva

Our web booking conversion was 3.2%. After the React Native app, we hit 34%. Same market, same product — completely different experience for users.

Rafiq Islam
CEO, SwiftRide BD

They handled the Play Store rejection, the Apple review, the bKash integration and crash monitoring in the first month. I didn't have to manage anything.

FAQ

Questions about mobile app development

React Native is ideal if your team knows JavaScript/TypeScript or you need deep ecosystem integrations (payments, maps, third-party SDKs). Flutter is better for highly custom, pixel-perfect UIs with complex animations. We'll recommend the right fit after your discovery session — there's no universal answer.
