React Native Development
React Native lets one team build iOS and Android apps from a shared TypeScript codebase while still reaching native capabilities when needed. Renvric helps you judge whether it suits your product, then builds with attention to navigation, performance, native modules and the realities of store release.
Start your project
What React Native is, and what it is not
React Native renders real native interface components driven by JavaScript or TypeScript code written in the React style. It differs from a wrapped website because the screens use platform controls, and it differs from fully separate native apps because most logic and many screens are shared.
Sharing is not total. Some features need platform-specific code, and the project still needs to handle two operating systems, two sets of store rules and two sets of devices.
Where it fits and where it does not
- Consumer and business apps with standard interface patterns, lists, forms, maps, media and notifications.
- Teams already skilled in React and TypeScript who want to reuse that knowledge and shared logic with a web product.
- Products where speed of iteration across both platforms matters more than the last degree of platform polish.
- Poor fit: graphically intensive games, heavy real-time audio or video processing, or apps built mainly around a newly released platform feature.
- Poor fit: very small apps with one platform target, where native may be simpler.
Key technical decisions
Managed toolchain or bare
A managed toolchain speeds setup and over-the-air updates; direct native project access gives more control over custom modules.
Navigation and state
Choice of navigation library and state or data-fetching approach affects testability and how screens share data.
Native modules
Camera, Bluetooth, biometrics and payments often depend on native code. Maintenance status of each library matters.
Architecture generation
Newer React Native releases change the bridge and rendering layer. Library compatibility needs checking before upgrades.
Offline and storage
Local database, secure storage for tokens and a sync approach where connectivity cannot be assumed.
Share the outcome you need and Renvric will recommend the smallest useful next step.
An example of the trade-off
Consider a field-sales company needing an order-taking app for iOS and Android, integrated with its ERP and able to work without signal. A shared codebase makes the order flow and sync logic one piece of work. The barcode scanner and signature capture may need native modules, which are tested on real devices from each platform. The decision is sound if those modules are mature; it deserves a spike first if they are not.
How Renvric approaches the work
Fit and risk check
List required device capabilities and review the library ecosystem for each.
Design and prototype
Design with platform conventions in mind and test the riskiest interaction early on a device.
Foundation
Set up project structure, navigation, state, environments, linting and continuous builds.
Feature delivery
Build in increments, each demonstrated on physical iOS and Android hardware.
Hardening
Profile performance, test low-end devices, accessibility and offline cases.
Store release
Prepare signing, store listings, privacy declarations and a staged rollout.
Quality and security controls
- Automated unit and component tests, with end-to-end flows run on emulators and a device cloud.
- Tokens and secrets kept in the platform secure store, never in plain storage or source control.
- Dependency audits, because the JavaScript ecosystem changes quickly and abandoned packages are a real risk.
- Crash and performance reporting wired in before release, so launch problems are visible.
Costs, upgrades and ownership
Cost is shaped by the number of screens, native capabilities, integrations, design effort and testing across devices. Running costs include annual developer accounts, store review cycles and keeping up with React Native and operating-system updates. Plan for upgrades as routine maintenance, not as an occasional rescue. Renvric documents the build so your team can own it.
Common questions
What is included in react native development?
Typically a feasibility check on native capabilities, interface design, the shared TypeScript application, native modules where needed, API integration, automated and device testing, build pipelines and store submission support. Backend work, analytics and post-launch maintenance can be included or scoped separately.
Who is it suitable for?
It suits teams wanting iOS and Android apps from largely shared code, especially those with React skills or a React web product. It is a weaker choice for graphics-heavy or hardware-intensive apps, or when a single platform is all you need.
How long does delivery take?
It depends on screens, integrations and native features. Work is planned in increments so a testable build appears early, and store review adds time at the end. Renvric proposes a schedule after the capability check rather than before it.
What affects cost?
Number of screens and flows, native modules, offline sync, backend integration, design depth, accessibility, test device coverage and release support all play a part. Upgrades and store fees continue after launch. Reusing logic with a web product can reduce build effort.
How does Renvric control quality and risk?
By testing risky native features early on real devices, using automated tests plus device-based checks, auditing dependencies, keeping secrets in secure storage, and wiring crash reporting before launch. Acceptance criteria are written, and releases are staged so problems are contained.
