Service — Apps

iOS and Android, From One Codebase.

React Native and Expo — one codebase, two app stores, no compromise. Near-native performance, native modules where needed, and a single team shipping to both platforms simultaneously.

What We Build

Customer apps, internal tools, and everything in between.

Customer-Facing Apps

Loyalty programmes, booking flows, e-commerce storefronts, content feeds. Polished experiences that keep users coming back.

Internal Tools

Field-service dashboards, sales enablement, dispatch tracking, inventory management. Purpose-built for the teams that use them daily.

Backend Integrations

REST and GraphQL APIs, real-time data sync, push notifications, payment gateways. The plumbing that makes the front end useful.

Our Approach

One codebase. Near-native feel. No shortcuts.

React Native with Expo is the default stack. A single TypeScript codebase produces both iOS and Android builds — same logic, same UI components, same test suite. Expo handles the build pipeline, over-the-air updates, and push notifications so the team can focus on features, not tooling.

When a feature demands hardware-level access — Bluetooth LE, offline-first storage, augmented reality, custom camera pipelines — native modules are written and integrated into the same project. No separate app, no separate team.

TypeScript runs in strict mode across the entire codebase. Type safety catches bugs before they reach a device, not after a one-star review. Backend services are either Sunrise-built or integrated with existing APIs through a clean abstraction layer.

If a cross-platform framework cannot deliver the required experience, Sunrise will say so upfront — not after three months of billing.

Process

From scoping to the app stores in five phases.

01

Scoping

Define the problem, the audience, the platform requirements. Decide what belongs in v1 and what waits for v2. Every feature earns its place through a clear user need.

02

Wireframes

Screen-by-screen flows, navigation maps, interaction patterns. Reviewed and approved before any code is written. No surprises at launch.

03

Build

Feature-complete builds delivered every two weeks. Real devices, real data, real feedback loops. Each sprint ships something testable.

04

App Store Submission

Screenshots, metadata, privacy policies, review guidelines. Sunrise handles the entire submission process for both Apple and Google.

05

Post-Launch

Analytics dashboards, crash reporting via Sentry, performance monitoring. Ongoing iteration based on real user behaviour, not assumptions.

Deliverables

Everything you need. Nothing you don't.

iOS app — App Store ready
Android app — Google Play ready
Full source code in a Git repository
Backend API if scoped — Sunrise-built or integrated with existing systems
Push notification infrastructure
Analytics + crash reporting (Sentry / Firebase)
App store account setup and first submission
Technical documentation — architecture, deployment, environment setup
Optional web companion app sharing the same codebase
Optional version retainer for ongoing updates and store compliance

Why It Matters

The cost of building it twice.

Separate iOS and Android codebases mean separate teams, separate bug lists, separate release cycles. Every feature ships twice, every fix ships twice, every regression is discovered twice. Maintenance costs double and parity drifts with every sprint.

A web-only approach avoids duplication but loses the mobile user. App-store presence, push notifications, offline access, camera and biometric integration — these are expectations, not nice-to-haves. Users who cannot install the app often do not come back.

React Native delivers near-native quality for roughly 90% of use cases. For the remaining 10% that genuinely need platform-specific code, native modules slot into the same project. One team, one codebase, two stores, no compromise on the experiences that matter.

Frequently Asked

Common questions, honest answers.

Why React Native instead of fully native?+
React Native delivers near-native performance from a single codebase. For the vast majority of apps — around 90% — users cannot tell the difference. The remaining 10% that need deep hardware access (Bluetooth LE, AR, custom camera pipelines) can still use native modules within the same project. One team, one codebase, two stores.
How long does an app project take?+
Simple apps with limited screens: 6–10 weeks. Feature-rich apps with backend integration: 12–20 weeks. Every project receives a phase-by-phase timeline at proposal stage, with feature-complete builds delivered every two weeks.
Who handles App Store submission?+
Sunrise manages the full submission process — screenshots, metadata, privacy policies, review-guideline compliance. Both Apple App Store and Google Play are covered. The accounts belong to the client.
Can the team update the app after launch without Sunrise?+
Yes. The full source code and Git history are handed over. Any React Native developer can pick up the project. Sunrise also offers an optional version retainer for ongoing updates, store compliance changes, and OS version support.
Does the app need a backend?+
Most apps do. If the project requires user accounts, data storage, or third-party integrations, Sunrise builds the backend as part of the same engagement. If a backend already exists, the app integrates with it via API.
What does an app cost?+
Every project is quoted on scope. Get in touch with what the app needs to do and Sunrise will return a fixed proposal within 48 hours. No hourly billing, no open-ended retainers unless requested.
