CodeSpace Infotech
Mobile App Development

Two platforms, one disciplined codebase.

React Native apps that share business logic across iOS and Android while keeping platform-specific navigation, gestures and polish where users notice them.

  • Shared codebase
  • Native modules
  • OTA updates

React Native interface example by CodeSpace Infotech

One cross-platform codebase shipping to iOS and Android without feeling generic.

Overview

Cross-platform without the compromise tax.

Cross-platform goes wrong when teams share everything, including the parts that should differ. We share logic, networking and state, and branch the interface where each platform expects different behaviour.

Why it matters

Two native teams is expensive. A single well-architected React Native codebase covers both platforms without the app feeling like a wrapped website.

What we build

Cross-platform apps in TypeScript, shared design systems, native module bridges, over-the-air updates and automated store delivery.

Who it is for

Startups shipping to both platforms on one budget, and teams with existing React expertise who need mobile quickly.

Capabilities

What we handle from strategy to delivery.

Six areas we take responsibility for on react native engagements — no handoff gaps between them.

  • 01

    Cross-platform strategy

    What is shared, what stays platform-specific and why.

  • 02

    Shared UI system

    One typed component library rendering natively on both platforms.

  • 03

    Native module integration

    Camera, biometrics, Bluetooth and other device capabilities.

  • 04

    State & offline data

    Predictable data flow with caching and background sync.

  • 05

    Performance tuning

    Reanimated interactions, list virtualisation and startup profiling.

  • 06

    CI/CD & OTA releases

    Fastlane pipelines, store submission and over-the-air fixes.

Built for real-world results

Standards we hold every react native project to.

01
One codebase
iOS and Android from a shared core
02
Native feel
Gesture-driven, 60fps UI
03
OTA updates
Fixes without a store review
04
Faster delivery
Shared logic, shared tests
How we work

From first conversation to a product that is ready to grow.

01Discover

We map the target devices, user context and platform requirements before committing to an approach.

We review requirements, existing analytics, competitors and user needs to understand where react native will create the most value. Nothing is proposed before the problem is clear.

Deliverables

  • Feature scope
  • Device and OS targets
  • Store requirements

Typical activities

  • Stakeholder workshop
  • Platform review
  • Requirement capture

Success criteria

A clear, shared understanding of the problem, scope and expected outcome.

02Define

We agree the release plan, architecture and offline behaviour so the app holds up in real conditions.

We turn research into a clear product direction, priorities and information architecture. Scope, sequencing and technical direction are agreed in writing before work starts.

Deliverables

  • App architecture
  • Release plan
  • Data and sync model

Typical activities

  • Flow mapping
  • Technical design
  • Estimation

Success criteria

Everyone understands what is being built, in what order, and why.

03Design

We design platform-native screens, states and motion rather than porting a web layout.

We translate the agreed structure into a polished, responsive interface — every state, breakpoint and edge case included, reviewed together as we go.

Deliverables

  • Screen designs
  • Interaction states
  • Icon and store assets

Typical activities

  • Wireframing
  • Native pattern review
  • Prototype

Success criteria

The experience is validated and ready for implementation.

04Build

We implement the app with clean modules, native performance and instrumented crash reporting.

We turn approved designs into production-ready software using maintainable components and a scalable architecture. You see working software throughout, not just at the end.

Deliverables

  • Production build
  • API integration
  • Offline handling

Typical activities

  • Feature development
  • Device testing
  • Code review

Success criteria

The product works reliably across the required devices and scenarios.

05Validate

We test across real devices, run beta builds and resolve issues before submission.

We test the product against the real requirements, profile performance and surface issues before launch rather than after it.

Deliverables

  • Test reports
  • Beta build
  • Crash-free baseline

Typical activities

  • Device-farm testing
  • Beta feedback rounds
  • Performance profiling

Success criteria

Critical issues are resolved and the product is ready for launch.

06Launch

We handle submission, staged rollout and post-release monitoring across the stores.

We deploy, review the built product in production and refine the details that only appear in the real thing. Monitoring and handover happen at the same time.

Deliverables

  • Store submission
  • Release notes
  • Monitoring dashboards

Typical activities

  • Review response
  • Phased rollout
  • Post-launch fixes

Success criteria

The product is live, verified, documented and ready for users.

What you receive

Everything handed over, nothing locked away.

Concrete output at the end of a react native engagement — code, assets and documentation you own.

    iOS and Android builds from one codebase
    Native module implementations where required
    OTA update pipeline
    Store listings for both platforms
    Automated build and release workflow
Technologies

The stack we reach for first.

Chosen per project constraints — this is the starting point, not a rule.

Frontend

  • TypeScript

Mobile

  • React Native
  • Expo
  • Reanimated

Delivery

  • Fastlane
  • Sentry
Why CodeSpace

Outcomes, not just output.

Clients stay because the work reduces risk and cost after launch, not only because it looks good at handover.

  • 01

    Less rework

    Platform differences are decided up front, not discovered mid-build.

  • 02

    Faster decisions

    One team, one backlog, one release cadence.

  • 03

    Better performance

    Animations on the native thread and profiled list rendering.

  • 04

    Clear handoff

    TypeScript codebase familiar to any React developer.

  • 05

    Long-term thinking

    Upgrade path planned around Expo and RN release cycles.

FAQ

Questions we get asked.

Still unsure about something on react native? Ask us directly — we answer honestly, even when the answer is no.

For the vast majority of apps, yes. Animation-heavy or hardware-intensive screens can be implemented natively inside the same app.

We usually start with Expo for speed and move to a custom dev client when native dependencies require it.

Yes, brownfield integration is supported for incremental adoption.

Yes, when built properly — native navigation, gestures and animations running off the JS thread.

Business logic, types and API clients are usually shared. UI components are not.

Yes. Native modules can be added for any capability the ecosystem does not cover.

Most JavaScript-level fixes ship over the air; native changes go through the stores.
