Mobile Apps
Apps people actually
want to come back to.
We design and build iOS, Android, and cross-platform mobile applications. From concept and UX through to App Store launch and ongoing support. Built for users, not just for the portfolio.
What we build
From native iOS and Android to cross-platform. Here's the full range of what we build.
iOS Development
Native iOS applications built with Swift and modern Apple frameworks, delivering the performance, polish, and platform-specific behaviours that App Store users expect. Engineered to Apple's standards from top to bottom.
Android Development
Native Android apps built to reach billions of active devices worldwide. From Google Play submission to Material Design implementation, we build apps that perform reliably across the full spectrum of screen sizes and manufacturers.
Cross-Platform Apps
React Native lets us build once and deploy to both iOS and Android without sacrificing performance or user experience. For most businesses, cross-platform cuts time-to-market and ongoing maintenance costs without meaningful compromise.
UX & App Design
App success lives and dies by user experience. We design mobile interfaces that feel intuitive. From early wireframes and journey mapping through to high-fidelity prototypes refined with real user feedback before development begins.
App Store Launch
Getting accepted to the App Store and Google Play isn't always straightforward. We handle the full submission process, store listings, screenshots, and metadata optimised for discoverability. We manage the review process through to approval.
Maintenance & Support
Apps need ongoing care. OS updates break things, users report bugs, and features need adding. We offer maintenance retainers that keep your app current, compatible with the latest releases, and improving based on real user feedback.
How we work
From first conversation to live on the App Store, a process built around reducing risk at every stage.
Discovery & Scoping
We define your app's goals, target audience, and core feature set, scoped honestly so there are no surprises once development begins.
UX & Prototype
User journeys, wireframes, and interactive prototypes that let you validate the concept before a line of code is written. We iterate until it feels right.
Development
Native or cross-platform development with clean architecture, rigorous code review, and regular build releases so you can test progress throughout.
Launch & Support
Full submission support to both app stores, post-launch monitoring, crash reporting, and an ongoing maintenance retainer to keep everything running smoothly.

Holborn Assets were running client policy management through a third-party platform that constrained their brand and their roadmap. We designed and built a proprietary app to replace it — giving clients self-service portfolio access, advisers a tool to manage their books, and prospects a free utility layer that generates leads. Five stars on both stores.

Frequently asked questions
Can't find what you're looking for? Get in touch and we'll answer directly.
Both. We'll recommend the right approach for your situation. Native iOS (Swift) and Android (Kotlin) give the best platform-specific performance. Cross-platform with React Native is often the better choice for businesses that need to launch on both platforms quickly and maintain a single codebase. We'll advise honestly based on your requirements and budget, not on what's easiest for us.
A focused app with a defined feature set typically takes 12–20 weeks from brief to App Store launch. More complex applications with custom backends, third-party integrations, or advanced functionality take longer. We provide a clear timeline during our discovery and scoping phase so you know exactly what to expect before we start.
Mobile app development varies significantly by scope. A focused MVP starts from around £15,000. Full-featured consumer or business applications are scoped individually. We always recommend starting with a clearly defined MVP. Launch something focused and well-built, then iterate based on real user data rather than assumptions.
Yes, fully. We manage the entire submission process for both the Apple App Store and Google Play, including store listings, screenshots, preview content, metadata, privacy documentation, and age ratings. We're experienced with both review processes and handle any rejections or requests for additional information.
Yes. We regularly inherit apps from other developers, whether the original team has moved on, the codebase has become unmanageable, or the app needs a significant update. We'll audit what exists first and give you an honest assessment of whether a rebuild or an incremental improvement is the better path forward.
Yes. We offer monthly maintenance retainers covering OS compatibility updates, bug fixes, performance monitoring, and feature development. Mobile operating systems update regularly and apps that aren't actively maintained quickly accumulate compatibility issues. Our retainers exist to keep that from happening.
