Mobile App Development

iOS and Android from a single codebase. We build mobile apps in React Native (Expo) — from a fast MVP to a mature product — with native performance, offline support and a clean handover. You keep full IP ownership, including your App Store and Google Play accounts.

Overview

Overview: Cross-platform mobile, done right

Two native apps built and maintained separately is expensive and slow. We build in React Native — one TypeScript codebase that ships to both iOS and Android with native-level fluidity. You move faster, pay less and evolve one product, not two.

We're pragmatic: we start with a focused MVP to validate the idea, then grow it feature by feature. Every app runs on a modern, type-safe stack and is connected to your backend and data in real time.

What's included

What's included in mobile engineering:

01

Cross-platform build (React Native + Expo)

One codebase, both platforms — without giving up the native feel.

  • One codebase: A single TypeScript codebase for iOS and Android, with fast iteration and over-the-air (OTA) updates.
  • Native feel: 60fps navigation, platform-correct components and smooth gestures.
02

Backend & integrations

An app is only as good as its connection to your data and services.

  • API & backend: We connect to your existing system or build the backend from scratch (Node.js), with real-time data.
  • Auth & payments: Secure login, in-app payments and subscriptions compliant with store rules.
03

Native device capabilities

We use the device, not just the screen.

  • Push, offline & sync: Push notifications, offline-first architecture and background sync when the network returns.
  • Camera, GPS & scanners: Location, maps, camera and barcode/QR scanning for field and logistics apps.
04

Release & maintenance

Getting to the store is the start, not the finish.

  • Store release: We handle App Store and Google Play submission, requirements and review — the accounts stay yours.
  • Updates & monitoring: OTA updates, crash monitoring and iterative improvements after launch.
Tech stack

Our mobile technology stack

A modern, type-safe stack that keeps one product fast on both platforms.

Core

  • React Native + Expo: Cross-platform framework for iOS and Android from one codebase.
  • TypeScript: Static typing — our insurance against bugs as the app grows.

Backend & services

  • Node.js & REST/GraphQL: Backend and APIs feeding the app in real time.
  • Push & storage: Push notifications plus secure storage and sync.
