Let's Talk

Built for iOS

We develop iOS applications for businesses across the UK and Isle of Man. Mobile applications for iPhone and iPad that deliver a genuine native iOS experience - built using React Native with full access to iOS platform capabilities, designed to Apple's human interface guidelines, and built to App Store submission standards from the start of development.

iOS is the dominant platform for consumer applications in the UK market and the priority platform for most business mobile app projects. Users of iOS apps have high expectations for performance, design quality, and reliability - and the App Store review process enforces standards that ensure those expectations are met before an app is published. We build iOS applications that meet those expectations and pass that review reliably.

Every iOS application we build is designed and delivered personally by Owen Jones, OLXR's founder and lead engineer. We bring first-hand App Store experience - building, submitting, and maintaining live iOS products - to every iOS project we take on.

Who This Is For

Businesses that need an iOS application as their primary mobile channel to customers or field teams
Startups building a mobile product where iOS is the primary target platform for their user base
Organisations with an existing web platform that needs a companion iOS app for functionality a mobile browser cannot support
Businesses that have had an iOS app built previously and need it maintained, improved, or rebuilt
Companies that need an iOS app integrated with existing business systems and APIs
Businesses with iOS as their primary channel for customer engagement or revenue

Our Approach

1
Design to iOS Standards

We design to Apple's Human Interface Guidelines, using the navigation patterns, interaction models, and visual language iOS users expect. An app that fights these conventions feels wrong to users even when they cannot articulate why.

2
Build for App Store Approval

The App Store review process rejects apps that do not meet Apple's requirements - and those requirements cover a wide range of concerns including privacy, security, performance, and content standards. We build with App Store compliance in mind throughout development, not as a checklist to complete at the point of submission. Apps we build pass App Store review reliably because we account for Apple's requirements from the start.

3
Test on Real Devices

iOS applications need to be tested on real devices, not just simulators. Performance characteristics, touch responsiveness, battery consumption, and camera behaviour can all differ significantly between a simulator and a physical device. We test on a range of real iOS devices throughout development and provide TestFlight builds for client testing on your own devices before submission.

Why Choose OLXR

iOS users notice when an app does not feel right - even when they cannot articulate why. We design and build to Apple's standards by default, with App Store compliance baked in throughout development rather than bolted on at submission time.

App Store Experience

First-hand experience submitting and maintaining live iOS products

HIG-Compliant

Designed to Apple's Human Interface Guidelines from day one

Real Device Tested

Tested on physical iPhones and iPads, not just simulators

Senior-Led

Built by the founder, not delegated to juniors

Great iOS apps feel inevitable to the user - every interaction lands where they expect it to. We design and build for that, so your app earns its place on their home screen.

Frequently Asked Questions

Apple's standard review time is typically one to three business days for initial submission. If Apple's reviewers identify issues requiring changes, the review process restarts after the revised version is submitted. We aim to submit apps that pass review on the first attempt by building to Apple's requirements throughout development, but review times and outcomes are ultimately under Apple's control.

Yes - taking over maintenance and development of existing iOS apps is something we do. We review the existing app's code, architecture, and App Store configuration before taking it on, and give you an honest assessment of its current state and the work required to bring it to a standard we are comfortable maintaining. Apps built with significant technical debt may require more substantial work before they can be extended efficiently.

We design iOS apps to support the current iOS version and the two previous major versions - covering the significant majority of active iOS devices. Supporting older versions beyond that creates significant development and testing overhead for diminishing user coverage. We will recommend the right minimum iOS version for your specific app and user base.
