FOR MOBILE PRODUCTS THAT DELIVER

Mobile App Development

We build native and cross-platform apps that run reliably, feel great in the hand, and earn their place on your users' home screens.

Apps built to hold up

Whether you are launching a new app, adding a single capability, or rescuing a stalled project, we plug in where you need us and stay hands-on right through to release. You get straight recommendations, tangible deliverables, and a team that stays close through the critical stages.

  • Mobile Strategy & Discovery

    Get clarity before a line of code is written. We nail down the audience, the requirements, and a sensible scope, so your app launches from solid ground. Typical outputs: product scope and MVP definition; platform recommendation (native vs. cross-platform); feature prioritisation and roadmap; effort and cost estimate.

  • Native App Development (iOS & Android)

    We build native iOS and Android apps engineered for speed, rock-solid reliability, and a first-class feel on every device. Typical outputs: production-ready iOS and Android apps; app store submission and release; performance and stability tuning; a maintainable, documented codebase.

  • Cross-Platform Development

    We build cross-platform apps from one shared codebase, getting you to market sooner and keeping maintenance lean, with no visible drop in quality. Typical outputs: shared-codebase app for iOS, Android (and web where it fits); a consistent UI across platforms; faster release cycles; lower long-term maintenance effort.

  • Backend, APIs & Integrations

    We wire your app up to dependable backends and the systems you already run, covering APIs, data connectivity, and integration into your IT landscape. Typical outputs: API design and implementation; integration with existing systems and third-party services; secure data flows and authentication; a scalable backend architecture.

  • Modernisation & Legacy Replacement

    We bring tired apps up to date and retire the legacy pieces holding them back, one release at a time, so users never feel the ground shift beneath them. Typical outputs: modernisation assessment and migration plan; step-by-step replacement of legacy components; risk and dependency analysis; a clear route to a codebase your team can maintain.

  • Quality Assurance, Operation & Support

    We keep releases stable and operations smooth, from testing and app store publishing to maintenance and continued development. Typical outputs: automated and manual test coverage; a CI/CD and release pipeline; monitoring and crash reporting; ongoing maintenance and support.

What our clients say

Jim Kennedy
DRVN and OR have worked together since the earliest days of DRVN, and the relationship our teams built made the collaboration feel as if we were one company. OR's team was extremely knowledgeable and helped us deliver a very complex rewrite of a legacy connected vehicle system.

Start with a mobile workshop

Hands-on sessions that sharpen your app idea and turn it into a plan you can act on: a scoped MVP, a workable architecture, a modernisation path, or a prototype you can hold.

Mobile App Discovery / Scoping Workshop

Mobile App Discovery / Scoping Workshop

Target audience: Product Managers / Product Owners / Business Stakeholders / Founders Duration: Half day

Sharpen your app idea and settle on the right scope for a successful launch. In a few hours we get stakeholders aligned on a shared target, prioritise features, and define a realistic MVP along with the next steps.

App Modernisation / Legacy Assessment Workshop

App Modernisation / Legacy Assessment Workshop

Target audience: Product Owners / IT Leads / Developers Duration: Half day

Take stock of an ageing app before you decide its future. We weigh a rebuild against a refactor, surface the hidden dependencies, and map a low-risk route to a modern codebase.

Frequently asked questions

The questions we hear most often about this service.

Do you build native or cross-platform mobile apps?

Both. We build fully native iOS and Android apps where performance and deep platform integration matter most, and cross-platform apps where a shared codebase is the better trade-off. We help you choose the right approach for your product and budget rather than pushing one by default.

Can you take over or modernise an existing app?

Yes. We take over existing iOS, Android, and cross-platform apps, stabilise them, and modernise the codebase and architecture step by step, so you can keep shipping while we improve the foundation underneath.

Do you also build the backend and integrations behind the app?

Yes. An app is only as good as the services behind it, so we build the APIs, backends, and third-party integrations your app relies on, or connect cleanly to systems you already run.
