Mobile Application Development

iOS and Android apps built using React Native - a cross-platform framework that delivers genuine native performance and user experience from a single codebase, senior-led from day one.

Let's Talk

Built for Mobile

We design and build mobile applications for businesses across the UK and Isle of Man. iOS and Android apps built using React Native - a cross-platform framework that delivers genuine native performance and user experience from a single codebase, without the compromises that users notice and businesses pay for in support costs.

Mobile application development is a discipline with a high failure rate. Apps that look promising in development feel sluggish on real devices. Apps that work well on one iOS version break on another. Apps that launch successfully but are never updated lose users and generate negative reviews. We build mobile applications with production quality as the standard from day one - not something added in a polish phase before launch.

Every mobile application we build is designed and delivered personally by Owen Jones, OLXR's founder and lead engineer. We bring first-hand product experience - building, submitting, and maintaining real iOS and Android applications in React Native - to every mobile project we take on.

Who This Is For

Businesses that need a mobile app as a companion to an existing web platform or service
Startups building a mobile-first product and needing a technical partner to bring it to life
Companies whose customers or field teams need mobile access to business systems in a way that a mobile browser cannot adequately support
Businesses that have a web application and need to extend it to mobile without building two separate native applications
Founders with a mobile app idea who need honest guidance on what to build, what it will cost, and what the realistic timeline looks like
Organisations that need both iOS and Android coverage without paying for two separate development projects

Our Approach

1
Design for the Device

Mobile applications are not websites on a smaller screen. Users have different expectations, different interaction patterns, and different tolerances for performance and reliability on mobile. We design around the actual context - on the move, with one hand, in poor lighting, on a cellular connection.

2
Build for Both Platforms from the Start

React Native allows a single codebase for iOS and Android. But platform differences are real - navigation conventions, typography, permission models, app store requirements. We design and test for both throughout rather than treating Android as an afterthought.

3
Plan for the App Stores

The app store submission and review process is a significant source of delay in projects that have not planned for it. We account for app store requirements throughout development and manage submission as part of the engagement.

Why Choose OLXR

We have built and shipped mobile applications to both app stores as product owners and developers - not just as contractors executing a specification. That experience with real app store management requirements, real performance and compatibility challenges, and real users gives us a perspective on mobile development that pure delivery experience does not.

Honest Advice

Mobile apps cost more than most agencies suggest - we are upfront

Long-Term Support

OS updates, app store compliance, and feature development

Mobile apps are more expensive to build well than the initial quote often suggests - we surface these realities at the start rather than at the point where they create problems.

Frequently Asked Questions

For most businesses, React Native is the right choice. It delivers genuine native performance and user experience on both platforms from a single codebase, at significantly lower development and maintenance cost than two separate native applications. Native development is appropriate when your app needs capabilities that React Native cannot support, requires maximum performance for graphically intensive applications, or has a team with strong existing native expertise. We will give you an honest assessment of which approach is right for your specific requirements.

A focused mobile MVP with a defined feature set typically takes 10-16 weeks from a finalised brief to App Store and Google Play submission. A full-featured application with complex backend integration, offline capability, and multiple user types typically takes 4-6 months. App store review adds additional time - Apple's review process typically takes one to three business days but can take longer if revisions are required.

A focused mobile MVP typically starts from £20,000-£35,000 including the backend API. More complex applications with multiple user types, offline capability, significant backend complexity, and third-party integrations generally range from £40,000 upward. We will give you a realistic estimate after understanding your specific requirements - and we will tell you if your budget and your requirements do not align before work begins.

Yes - managing the app store submission and review process is part of every mobile development engagement. We prepare the app for submission, handle the review requirements, respond to reviewer feedback, and manage the release process for both stores. We also advise on app store optimisation - the metadata, screenshots, and descriptions that affect how your app is discovered and evaluated by potential users.

Mobile apps require more ongoing maintenance than web applications because they depend on operating systems that Apple and Google update regularly - and those updates can break functionality if not addressed. App store policy changes also require app updates to maintain compliance. We provide ongoing maintenance and support for the mobile apps we build, including OS compatibility updates, app store compliance updates, and feature development.
