React Native gets a bad reputation because a lot of agencies use it carelessly. When done properly, users cannot tell the difference from a native app for the vast majority of use cases.

We use React Native with TypeScript and the Expo managed workflow where it fits, or bare workflow when you need lower-level device access like Bluetooth or custom camera modules. The shared codebase typically covers 85 to 90 percent of the app, with small platform-specific files handling the rest. This ratio holds up well for content apps, marketplaces, booking tools, and SaaS dashboards.

Where React Native is not the right call, we tell you directly. Apps with heavy real-time graphics, complex animations tied to gesture velocity, or deep system-level integrations are better served by native builds. We make that assessment during scoping rather than after you have already paid for six weeks of work.

Each delivery includes working builds for both platforms, over-the-air update configuration via Expo Updates, and submission to both stores. You get one project timeline, one set of meetings, and two published apps.


How it unfolds

phase 01
Discovery & requirements

Defining goals, audience, platform scope, and technical boundaries before a single line of code is written.

phase 02
Architecture & design

UI wireframes, navigation flow, data model — decisions that shape everything downstream.

phase 03
Development sprints

Iterative build cycles with checkpoint reviews, keeping scope aligned with timeline and budget.

phase 04
Testing & store submission

Device-specific QA, performance checks, and guided submission to App Store and Google Play.


What the engagement covers

Week 1 — Technical fit assessment and spec

We review your feature list against React Native capabilities honestly. If native is the better path, we say so here.

Weeks 2–9 — Development

  • Shared component library setup
  • Navigation structure and state management
  • API integration and local data handling
  • Platform-specific adjustments for iOS and Android
  • Push notification setup for both platforms

Week 10 — QA

  • Testing on physical iOS and Android devices
  • Performance profiling for slow renders and memory leaks
  • OTA update pipeline verification

Week 11 — Dual submission

  • App Store and Google Play submissions handled in parallel
  • Review response management included
