One codebase.
Two native apps.
Cross-platform iOS and Android apps built with React Native and Expo. Pixel-perfect on both platforms — without the web-view compromise or the cost of two separate teams.
The problem
Two native apps means two codebases, two teams, two release schedules, and bugs that only appear on one platform. Most startups can't afford that — and shouldn't have to.
Our approach
React Native with Expo lets us share 90% of the codebase while delivering platform-native UX. One team owns both apps, ships both simultaneously, and fixes a bug once.
The result
A consistent product experience on iOS and Android, delivered in half the time, at half the ongoing maintenance cost — with OTA updates so you can ship fixes without waiting on Apple.
App store ready
from day one.
Every engagement includes everything needed to launch on both stores — not just the UI layer.

API integration
REST / GraphQL, offline sync
CI/CD for mobile
EAS Build, TestFlight, Play Console
Security hardening
Certificate pinning, data encryption
Analytics & crash reporting
Sentry, Amplitude, or Firebase
3 months post-launch support
Bug fixes, store updates, guidance
From concept to
app stores in 11 weeks.
You can install and use the actual app on your device from week 3 onwards — not a simulator, not a prototype.
Discovery & UX Scoping
We map your user flows, define the feature set, and align on the native UX patterns that feel right for each platform. We leave with a defined scope and a Figma prototype for the core flows.
Deliverables
- User flow diagrams
- Figma prototype (core flows)
- API contract
- Project timeline
Design & Setup
Full Figma designs for iOS and Android (same content, platform-appropriate interactions). Engineers set up the Expo project, CI/CD, and backend connectivity in parallel.
Deliverables
- Figma designs (iOS + Android)
- Expo project scaffold
- EAS Build pipeline
- Backend API setup
Feature Development
Iterative sprints with a TestFlight / Play Console build every Friday. You can install the actual app on your device and give feedback in real time — not on a browser simulator.
Deliverables
- Auth + onboarding flow
- Core feature set
- Push notifications
- Offline data layer
QA & Platform Review
Device testing across popular iOS and Android models, performance profiling, accessibility audit, and preparing App Store / Play Store submissions with all required assets.
Deliverables
- Device compatibility report
- Performance audit
- Store screenshots & metadata
- App Store / Play Store submission
Launch & Handover
App goes live. OTA update pipeline is configured so you can push JS-layer fixes without a full app store review cycle. Full documentation and 90-day support included.
Deliverables
- App store launch
- OTA update pipeline (EAS Update)
- Runbook & documentation
- 90-day support period
Modern React Native,
not legacy Expo.
We always target the latest stable React Native and Expo SDK. No legacy workarounds, no outdated patterns.
Two ways we
approach mobile.
One codebase. Two native apps.
React Native Apps
We build cross-platform mobile apps with React Native that feel native — not like a website wrapped in an app shell. The same engineers own the iOS and Android experience, keeping behaviour consistent and the codebase lean.
- React Native + Expo SDK — latest stable
- Platform-specific UI polish (HIG & Material)
- Native modules when JavaScript isn't enough
- Expo EAS Build for reliable CI/CD
- OTA updates via EAS Update (no store wait)
Share logic. Own the experience.
Cross-Platform Architecture
The biggest cost in mobile isn't writing code twice — it's maintaining two separate teams with diverging products. We architect for maximum code sharing without sacrificing the native feel that users on each platform expect.
- Shared business logic, API layer, and state
- Platform-specific navigation patterns
- Dark mode, dynamic fonts, and notch handling
- Accessibility on iOS (VoiceOver) and Android (TalkBack)
- Gradual migration from web or native apps
Built for teams
building for mobile.
Mobile-First Startups
Your product lives on mobile — and you need an app that feels like it was designed by people who use iPhones and Android phones every day, not developers who treat mobile as an afterthought.
- —Core product experience is on mobile
- —Need iOS and Android from day one
- —Want to ship fast without compromising quality
Web Products Going Mobile
You have a successful web product and want to extend to mobile without hiring a separate iOS / Android team. We build the mobile app against your existing API.
- —Existing web product with an API
- —Users requesting native app
- —Want to avoid two separate mobile teams
Enterprises Mobilising Workflows
Internal tools, field service apps, or B2B platforms that need to work on mobile — often offline, often with complex integrations. We build for enterprise reliability.
- —Field workers who need offline access
- —Existing enterprise systems to integrate
- —Needs MDM / enterprise distribution
