Mobile app development in the UK: market stats
The British mobile market is anything but pocket-sized. As 5G coverage rapidly expands nationwide, over half the UK population already enjoys faster mobile internet speeds — and telecons plan for complete coverage by 2028.
Likewise, the revenue expectations for the mobile app development market in the UK follow suit: from £7.36bn in 2024, it’s projected to grow to £9.24bn by 2028 on a 5.85 per cent CAGR.
Fintech leads the charge, as contactless payments became a necessity in 2020 and fully digital neobanks rose to challenge traditional institutions. Some of Vention’s UK fintech customers, like the paytech startup Curve and interface provider Unlimint, capitalised on the rise in demand and expanded their offers with the solutions we’ve crafted for them.
Other technologies like VR, complex mobile games, and health and fitness-oriented wearables also help keep the mobile market vibrant.
We’ve seen it first-hand. As a mobile app development company with a dedicated engagement team based in London, Vention’s engineers have crafted hundreds of mobile solutions for the UK market, delivering reliability, innovation, and impact since the first iPhone.

Have you got a mobile app idea but are struggling to pin down its execution?
A discovery session guided by tech and market experts might just be the direction you need. Here’s a suggestion from Glyn Roberts, our UK CTO of Digital Solutions:
CTO of Digital Solutions at Vention
"Product discovery workshops (PDWs) can provide great value for many companies, including startups, incubator projects, and established businesses launching new products. These workshops are instrumental in the early stages of custom mobile app development to understand user needs, market demands, and technical feasibility.
A well-executed PDW takes 1 to 6 weeks and results in a clear project roadmap, with accurate product goals and clearer cost estimations, laying out all the potential challenges and risks of the initiative. By engaging stakeholders early, these workshops help ensure that the project aligns with business objectives and customer expectations.
The benefits are significant. A well-structured roadmap accelerates production and time to market, reduces costs, and minimises potential bugs by addressing the hardest issues early in the process. Additionally, as the project’s goals and requirements are documented in advance, PDWs enhance communication among team members and managers, with everyone on the same page and able to check progress against the original plan.
If you don’t know how to start your project, begin with a PDW."
Every mobile app depends on must-have features.

How we build mobile app solutions
Our step-by-step development process was established to address your mobile app's pain points, critical concerns, and technical nuances from the very start. We abide by Apple’s Human Interface Guidelines, Google’s Material Design, and Samsung’s One UI Design in every app we craft for their respective systems.
Initial consultation
First, we chat. Talking to you lets us understand your business objectives, intended strategy, target audience, and the role your mobile app will perform. From there, we can identify the key features your project requires and start our technical considerations for achieving them.
UI/UX design
Then, we prototype design blueprints and map possible user journeys. Our core concern is to structure a product with pristine inner workings and sensational user experiences: your solution is on the right track when both the front- and backend are impressive.
Development and integration
This is where coding truly begins. Our engineers pick your solution’s tech stack based on the requirements established during the previous phases alongside the tools, frameworks, and possible integrations the final product will have.
QA and testing
Once your mobile app is structured, our QA specialists perform intensive tests to ensure no stone is left unturned. Functionality, reliability, load stress, security, and compatibility are thoroughly tested so that any quality-compromising issues are flagged and fixed before deployment.
Launch and deployment
The deployment stage begins with a final test. To deem your solution ready for the great outdoors, we first launch it in a staging environment that mirrors real-world conditions to ensure it meets platform guidelines. Once approved, we can submit it to the App Store and Google Play for publishing and launch it in real life.
Cue the champagne pop: Your mobile app is live!
Training and documentation
After celebrating, we’re back to work. A product is only as useful as its users make it to be, so we train your stakeholders to operate your new mobile solution so that they adopt it quickly. We also oversee the entire project documentation to simplify future updating efforts.
Maintenance and ongoing support
Lastly, at your request, our experts monitor your mobile app post-launch for potential errors and usage patterns, then address user feedback and solve any immediate issues. This is an essential step to understand which areas to prioritise with improvements.
Our approach to mobile app development
We believe technology should go hand-in-hand with a human touch. That’s why you’ll have a dedicated engagement manager here in the UK to guide you during our mobile app development journey.
Our London office is always open for us to communicate face-to-face or, if you prefer, we can visit your office too. Here, you’re always supported by professionals you can trust.
On the technical side of development, every project we undertake follows these four tenets:
Quality сontrol
-
We document all requirements and objectives, regularly reviewing and updating them to align with your project goals and needs.
-
Our devs run unit, integration, and regression tests using automated frameworks to ensure code quality. We also perform extensive manual testing to identify usability and functionality issues.
-
We conduct regular code reviews to maintain coding standards and use static code analysis tools to detect vulnerabilities and issues early.
Security and сompliance
-
Our engineers follow the best practices of mobile app security and compliance for every stage of the software development life cycle.
-
We perform regular security audits for your app and use automated tools and manual testing methods to detect and address any vulnerabilities.
-
Vention experts help you ensure compliance with GDPR, PCI DSS, and other regulations through detailed records of compliance measures, data handling, and security protocols.
Baked-in scalability
-
We develop secure APIs for seamless app-backend communication, use microservices for easy scalability, and thoroughly test integrations for reliability and early issue detection.
-
We implement cloud infrastructure for further scalability, use load balancing to distribute traffic across servers, and enable auto-scaling to adjust resources automatically based on usage.
User-centric design
-
Our UI/UX experts can quickly prototype a variety of tailored wireframes to pinpoint one that resonates best for your business and your customers.
-
Key to user satisfaction, our design teams implement polished, intuitive interfaces that enhance the app's user experience and keep customers engaged on the screen

Jamie French
UK engagement manager
Hear from our expert
"User-centric design is crucial for creating engaging experiences in mobile app development. As a former developer myself, I can say that intuitive designs with short learning curves focussing on the end user are the most effective path towards high adoption rates and retention.
We believe in a collaborative approach here at Vention. We work closely with our partners to align the app’s design with their vision, business goals, and what their customers expect. This collaboration is one of constant communication, and our partner’s insights are integral to the design process. By pairing these insights with user feedback, we create apps that meet functional requirements and resonate with customers on a deeper level.
Our commitment to user-centric mobile app design ensures that our apps deliver value to the business and its users. By putting the user first, we create practical, efficient, and engaging mobile apps that, on top of it, are also visually appealing. That’s how we spell long-term success."

Testimonials
We’re in for the long haul. Check out what just a few of our partners had to say about our collaboration:
“We mainly used Vention for Design, Node.js, iOS Swift, Test automation, DevOps to improve different areas of the products and launching new features. (...) Not only they were highly skilled professionals in their own domain, but also they have good communication skills. We learnt from each other on technical knowledge and also on project / product management side. They were very engaging and proactively listening for feedbacks and improve ways of working.”
“We initially hired Vention to design and develop a new mobile application and that evolved into an ongoing full-stack relationship. We were very happy with the initial specification, the design prototypes and the accuracy of time estimates on the sprints. The app was completed and we decided to continue the relationship. (...) We are very pleased with the work they have produced for us and continue to provide quality work for us.”
“We needed a skilled team that could quickly ramp up and stay for the long term. For the project itself, they used various open source software including Django on the backend, Swift for iOS, and Kotlin for Android. It's primarily a native mobile application but is web-based as well. (...) The product is very successful and their work has been outstanding. The service they provide is outstanding. They’re excellent engineers who know all the tools.”
