Expo
Expo is the fastest way to build cross-platform mobile applications for iOS and Android that share a single React Native codebase. We use Expo to deliver native mobile experiences without the overhead of maintaining separate iOS and Android teams, keeping quality high and development costs predictable.
Why Expo and React Native
- Single codebase, two platforms, Write once, run on iOS and Android. Up to 90% of code can be shared between platforms, dramatically reducing development and maintenance costs compared to native apps.
- Native performance, React Native renders to native UI components, not a web view, so users get a genuinely native feel with smooth animations and platform-appropriate interactions.
- Expo SDK, Expo’s managed SDK provides ready-to-use modules for camera, location, push notifications, biometrics, file system, and hundreds of other native capabilities, without writing platform-specific code.
- Over-the-air updates, With Expo Updates (EAS Update), you can ship JavaScript bundle updates to users instantly, without going through App Store or Play Store review cycles.
- Expo Application Services (EAS), Cloud-based build, submission, and update infrastructure. No Mac required to build iOS apps, and automated submission to both app stores.
Our Mobile Development Approach
We build Expo apps with TypeScript, Expo Router for file-based navigation, and Zustand or Redux Toolkit for state management. We integrate with your existing Python backend via REST or GraphQL APIs, handle authentication with secure token storage using Expo SecureStore, and configure push notifications through Expo’s notification service.
We set up EAS Build from the start, giving you automated builds for both platforms on every merge, with TestFlight and internal Play Store track distribution for beta testing.
What We Build With Expo
- Customer-facing mobile apps for B2C and B2B products
- Field service and logistics apps with offline-first capabilities
- Internal enterprise tools for mobile workforces
- Apps that share significant business logic with a web frontend (Expo for Web)
