Mobile App

We build cross-platform mobile apps for iOS and Android from a single React Native/Expo codebase. That path makes sense when you genuinely need native hardware access — camera, push notifications, location, Bluetooth. When you don't, a PWA (Progressive Web App) — one codebase covering both web and mobile, no store review to wait on — is usually faster and cheaper; we'll help you decide which fits based on what you actually need.

// Features

What's included

Cross-Platform Development

One codebase for both iOS and Android with React Native/Expo — a single development track instead of two separate teams.

Native Hardware Access

Camera, notifications, location, Bluetooth — we integrate native APIs when they're genuinely required.

Backend & API Integration

We can build the backend the app talks to as well — auth, data sync, push notification infrastructure.

PWA Alternative Assessment

Is native actually necessary, or would a PWA do the same job faster and cheaper — we settle this before the project starts.

Store Submission

App Store and Google Play submission, review tracking, and a developer account set up to stay yours.

Updates & Maintenance

Ongoing support for store updates, OS compatibility, and bug fixes.

// Process

How we work

Requirements & Platform Decision

We clarify which native capabilities are actually needed, and whether native or PWA is the right call.

Design

Interface design that respects iOS and Android's own design language, from a single component library.

Development

Core features, backend integration, and native modules built with React Native/Expo.

Testing

Testing on real iOS and Android devices, plus a check against store review guidelines.

Launch

Submission to the App Store and Google Play, developer account handover, and post-launch monitoring.

Common questions

Have you published mobile apps before?

Most of our portfolio is on the web and PWA side — on projects like Nexos Investment we built systems that run as installable, offline-capable PWAs. Native mobile app projects are a service we run end-to-end starting with this engagement, from development through testing to store submission.

Native app or PWA — which fits us?

If you don't genuinely need hardware APIs like camera, Bluetooth, or NFC, a PWA is usually faster and cheaper — one codebase covers both web and mobile, with no store review to wait on. We'll clarify your needs together and recommend accordingly.

Do you build iOS and Android separately?

No, we work from a single React Native/Expo codebase — supported by native modules where platform-specific behavior is required.

Who owns the store account?

Apple Developer and Google Play Console accounts are opened in your name at the start of the project; ownership of the app and authority to publish future updates always stays with you, we act only as the intermediary.
