React Native App Development in London
React Native apps for London businesses already invested in JavaScript and React. The practical advantage is not the framework itself but the continuity — the same team, the same language and often the same validation and business logic as your web application, which is a real saving that goes beyond the mobile build.
Why this comes up
The problem
The web team builds in React and a mobile app is needed. Hiring separate Swift and Kotlin developers for one product is hard to justify at your size.
What you get
What we deliver
- A React Native app rendering genuine native components on both platforms
- Shared logic with your web application where it makes sense to share
- Platform-specific behaviour where users expect it, rather than one interface everywhere
- Native modules where a feature needs platform APIs directly
- Over-the-air updates for changes that do not require store review
- Both store submissions and real-device testing across the range

London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.

React Native App Development in London — common questions
- Can our web developers build it?
- Largely, yes — React knowledge transfers directly. What does not transfer is mobile-specific work: navigation patterns, offline behaviour, store requirements and native debugging. Expect a learning curve there rather than assuming the skills are identical.
- How much code can we share with our website?
- Business logic, validation and API layers share well. Interface code mostly does not — a good mobile screen is not a responsive web page, and trying to share the presentation layer usually produces something that suits neither.
- What are over-the-air updates?
- JavaScript changes pushed to installed apps without a new store release, which is genuinely useful for fixes. Native changes still need a store submission, and store rules limit how far this can be stretched — it is a fast path for bugs, not a way to avoid review.
- Is performance good enough?
- For typical business apps, comfortably. The gap appears in heavy animation, complex lists and graphics-intensive work, where careful optimisation or native code becomes necessary. Most line-of-business apps never approach that boundary.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
