Have an app concept but need clarity on the next step?
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:
Glyn Roberts
UK CTO of Digital Solutions:
"Product discovery workshops (PDWs) can provide great value for many companies, including startups, incubator projects, and established businesses launching new products. They are instrumental in the early stages of custom mobile solution development to understand user needs, market demands, and technical feasibility.
A well-executed PDW takes one to six 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. So, if you don’t know how to start your project, begin with a PDW."
Every mobile app depends on must-have features.
Our experts can help you uncover yours.
Our success stories
Testimonials
We’re in for the long haul. Check out what just a few of our partners had to say about our collaboration:
CTO, Healthera
“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.”
CTO, Remotiv
“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.”
CEO, Carson Living, Inc
“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.”
Head of Delivery, Memrise
“Vention provides us with staff augmentation services. The team manages our mobile, web, and backend platforms. For our mobile team, we've split it into Android and iOS. Vention has provided us with a very good caliber of talent. They have excellent communication skills and are very good collaborators. They have a great mindset of getting things done. When we have a brief, Vention constantly excels at understanding our needs and asking questions. They're efficient and meet our needs, which is very valuable.”
Department Lead, Urban
“We needed an experienced iOS Engineer to work on improvements and new features of our iOS apps, as well as to lead the Apps discipline inside our team. Besides someone with great technical skills, we needed engineers who could be active in discussions, contribute to planning and great in communication, and that’s exactly what we got from Vention. The iOS Engineer delivered great quality work right from the start, implementing features to a high standard that have been resulting in conversion improvements, but also bringing his knowledge into the discussion of new features and improvements, contributing with very valuable inputs.”

How Vention builds mobile app solutions
Our step-by-step development process addresses your mobile app’s pain points, technical specifics, and core challenges from the outset. Every solution adheres to Apple’s Human Interface Guidelines, Google’s Material Design, and Samsung’s One UI Design, ensuring that each app we deliver feels native to its platform and flawless in every interaction.
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.
Then, we prototype design blueprints and map possible user journeys. Our core focus is to build a product with impeccable structure and an intuitive flow, where refined inner logic meets striking visual design and both the front- and backend leave a lasting impression.
Development and integration
This is where coding truly begins. Our engineers select the tech stack for your solution based on the requirements established during the previous phases, along with the tools, frameworks, and potential integrations that the final product will incorporate.
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 to identify and address any quality-compromising issues 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 publication and launch it in the real world.
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 in understanding which areas to prioritise for improvements.
Our approach to mobile app development
We believe that 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.

Hear from our expert
"User-centric design lies at the heart of every successful mobile experience. As a former developer, I’ve seen firsthand how intuitive interfaces with short learning curves drive stronger adoption and retention.
Vention believes in a collaborative approach. 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.
