( what we build )

Start with the journeys your users need.

We use React Native where it fits best: line-of-business apps, marketplaces, and consumer products that need both stores from one codebase.

MVP apps

Core flows, auth, API integration, and analytics shipped fast to validate demand.

Native modules

Custom Swift, Kotlin, and Objective-C bridges for hardware, payments, and SDKs.

Marketplace & on-demand

Multi-vendor, booking, and delivery apps with real-time maps and payments.

Migrations

Plan the move from an existing app, including feature parity, data and release continuity.

( engineering for quality )

Test the experience before each release.

Performance

Profile startup, lists, gestures and images, then address delays on representative devices.

Push, payments, auth

Firebase, Stripe, and identity providers wired end-to-end across both platforms.

Release preparation

Prepare listings and release builds, support store review, and plan staged rollouts.

Scale

Clean state, module, and API design that grows with the product.

Common questions

When is React Native a good fit?

React Native lets a team share JavaScript or TypeScript application code across iOS and Android. It can suit teams with React experience and products with similar journeys on both platforms. The amount of shared code depends on the interface and native integrations.

Can React Native apps access device hardware and native modules?

Yes. React Native supports native modules written in Swift, Kotlin, and Objective-C, plus community and third-party bridges for camera, GPS, push notifications, biometrics, and payment SDKs. We write custom native modules when an edge capability is required.

Can you migrate an existing app to React Native?

Yes. We assess which screens and integrations can move together, then plan the migration around existing users, data and release requirements. Some platform-specific code may still be needed.

How do you check React Native performance?

We profile release builds on representative iOS and Android devices. Tests cover startup, scrolling, animations, memory use and important native integrations, with targets agreed for your app.

How long does a React Native app take to build?

A focused MVP with core screens, API integration, and auth ships in 6-10 weeks. Feature-rich apps with real-time, payments, and admin panels take 3-6 months depending on scope.

Do you handle app store submission for React Native apps?

Yes. We manage App Store and Google Play submission, store listings, screenshots, review compliance, and release staging for both platforms from one pipeline.
