CROSS-PLATFORM APP DEVELOPMENT SERVICES

Cross-platform app development UK teams can build a business on

Most businesses need their app on iPhone and Android. Building two native apps means two codebases and twice the maintenance. A cross-platform app, written once in React Native or Flutter, runs on both, so one team ships each feature to both stores in the same release.

Each stage has a fixed price agreed after a discovery call, and you install every weekly build on your own phones as the app grows.

React Native or Flutter?

Both are mature and widely used. React Native uses TypeScript and suits teams that already work in React, which our web team does. Flutter uses Dart and draws its own interface, which helps when the design is highly branded. We recommend one based on your product, your design and who will maintain the code, not on habit.

When native is still the better call

Cross-platform is not always right. If the app leans heavily on one platform's newest features, needs widgets, watch apps or demanding graphics, or will only ever serve one platform, a native build is often simpler. We build native iOS apps in Swift and native Android apps in Kotlin too, so we have no reason to push you one way.

One design that respects both platforms

A shared codebase should not mean identical screens. iPhone and Android users expect different navigation, back behaviour and system controls. Our UI and UX design team designs one product with the right details for each, then tests it on both.

Accessibility on both platforms

We label controls for VoiceOver and TalkBack, respect each user's text size, keep contrast high and test with the screen readers switched on.

Notifications and analytics

One notification system serves both platforms from your admin panel. Analytics track the same events on each, with consent handled properly, so you compare like with like.

The back end behind the app

The app is the part people see. Accounts, data, payments and the admin your staff use sit on a server. We build it in Laravel with a Filament admin, as we do for our own products. Rated Clinics, a directory we built and run, and Guaranteed Hours, our compliance product, both run on that stack. Neither is a mobile app, but the discipline transfers: clear data, an admin that needs no developer and releases checked on staging. If the app is part of a subscription product, see our SaaS development service.

Two stores, one release

Apple and Google each review apps and updates, with their own rules that change over time. We check the current requirements as we plan, prepare the privacy details each store asks for, and use TestFlight and Google Play testing tracks so your testers try each build first.

Support after launch

iOS and Android both release a major version every year, and React Native and Flutter move with them. We keep the framework current, test against new versions and ship updates before users notice. If your app takes enquiries, it can feed the kind of WhatsApp lead handling we built for our client Opus Smile, described in our article on answering every lead.
