ENGINEERING SERVICE

One codebase, two stores, no compromise on feel

Cross-platform apps in React Native or Flutter, with native modules where the platform demands them. You get one team and one roadmap instead of two.

CAPABILITIES

What cross-platform delivery looks like

Shared product code with a native escape hatch, so a single team can hold quality on both stores.

React Native builds

TypeScript, the New Architecture, and Expo where it fits — with bare workflow when you need full control of the native projects.

Flutter builds

Dart with a rendering pipeline that guarantees identical output on both platforms, ideal for heavily branded interfaces.

Native modules on demand

Swift and Kotlin bridges for camera, Bluetooth, background work, or any SDK the cross-platform layer does not reach.

Performance tuning

Frame timing, list virtualisation, bundle size, and startup traces measured per platform rather than assumed to be equal.

Over-the-air updates

CodePush or EAS Update pipelines for shipping fixes in hours, inside what store policy actually permits.

Shared design systems

One component library and one set of tokens driving both apps, and often the web product alongside them.

HOW WE ENGAGE

A delivery rhythm that keeps both stores in sync

Four phases from framework choice through to two published apps on one release train.

01

Framework decision

A short assessment of your product, team skills, and native surface area, ending in a written recommendation — including when to go native instead.

02

Foundations and design system

Navigation, state, networking, and a shared component library stood up so both platforms diverge only where they should.

03

Parallel feature delivery

Weekly builds to TestFlight and Play internal testing simultaneously, with native modules written as the roadmap needs them.

04

Dual release and handover

Both store submissions, an over-the-air update channel, and a CI pipeline your team runs after we leave.

TECHNOLOGY

The cross-platform stack we build on

Both ecosystems, plus the native tooling that makes the escape hatch real.

USE CASES

Where cross-platform is clearly the right call

The shapes of product where one codebase saves real money without costing quality.

↗

Two platforms, one budget

Startups and product teams that need iOS and Android at launch without funding two separate engineering groups.

↗

Content and commerce apps

Products built from lists, forms, media, and checkout flows, where shared code covers almost the entire surface.

↗

Internal and workforce tools

Field, retail, and operations apps where consistency and delivery speed matter more than platform-specific polish.

↗

Existing web teams going mobile

React teams that can contribute to a React Native codebase from day one instead of hiring two new specialisms.

BUSINESS IMPACT

What one codebase actually saves

The savings are real, but they come from delivery structure rather than lines of code.

01

One roadmap, not two

Features land on both platforms in the same sprint, which removes the coordination tax and the platform-parity backlog.

02

Lower cost to maintain

Bug fixes and dependency upgrades happen once. Over a multi-year product life this is where most of the saving sits.

03

Faster fixes in production

Over-the-air updates put a JavaScript or Dart fix in users' hands the same day, without waiting on review.

04

A hiring pool you can actually fill

React and Dart engineers are easier to recruit and retain than paired iOS and Android specialists.

WHY ZIKOSOFT

Why teams choose us for React Native and Flutter

We have shipped both, and we will tell you when neither is the right answer.

✓

Framework advice without a house bias

We build in both and recommend from your constraints. Sometimes the honest recommendation is two native apps.

✓

Native depth on the team

Our engineers write Swift and Kotlin too, so hitting the edge of the framework is a normal Tuesday, not a crisis.

✓

Per-platform quality gates

We measure startup, jank, and crash rate separately on iOS and Android, because one codebase does not mean one behaviour.

✓

Upgrade paths planned

Framework and dependency upgrades are scheduled work with a documented path, not an annual emergency.

FAQ

Questions teams ask before choosing

The trade-offs behind cross-platform, answered plainly.

React Native or Flutter?
React Native if you have React engineers, share logic with a web product, or lean on the JavaScript ecosystem. Flutter if the interface is heavily custom and pixel-identical output on both platforms matters. Either can build almost any app well.
Will it feel as good as a native app?
For most product categories, yes, and users cannot tell. Where it will not is heavy graphics, intensive camera or sensor work, and interaction-heavy premium consumer apps. We flag that in the assessment rather than after the build.
How much cheaper is it than two native apps?
Typically thirty to forty percent on initial build and more over the maintenance life, provided the app is not dominated by native integrations. The saving shrinks fast when it is.
Can you add a second platform to an existing native app?
Yes, either as a brownfield cross-platform module inside the existing app or as a fresh build that reuses your backend and design system.
How do you handle framework upgrades?
Pinned versions, a scheduled upgrade cadence, and regression suites that run before and after. We leave you a documented upgrade path at handover.
