iOS and Android, From One Codebase.

Native iOS and Android apps built from one cross-platform codebase. Near-native performance, platform-specific modules where needed, and a single team shipping to both stores simultaneously.

What We Build

Apps users want to keep open

Customer-Facing Apps

Loyalty programmes, booking flows, online 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.

A modern cross-platform native framework is the default stack. A single, strictly-typed codebase produces both iOS and Android builds — same logic, same UI components, same test suite. The build pipeline, over-the-air updates, and push notifications are handled at platform level, 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 — platform-specific native modules are written and integrated into the same project. No separate app, no separate team.

Strict type-checking runs 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

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.

Wireframes

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

Build

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

App Store Submission

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

Post-Launch

Analytics dashboards, crash reporting, 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 private repository in your account
Backend API if scoped — Sunrise-built or integrated with existing systems
Push notification infrastructure
Analytics + crash reporting wired up
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.

A modern cross-platform native framework 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 a cross-platform approach instead of fully native?
Modern cross-platform native frameworks deliver 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 platform-specific 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 version history are handed over. Any developer fluent in modern cross-platform native frameworks 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.
