Solutions Across The Mobile Ecosystem

Bespoke App Development

We design and develop mobile applications that are uniquely tailored to individual business needs and objectives. Our robust development process starts with a comprehensive understanding of a business: it’s staff, industry and customers. This insight is used to identify opportunities for growth, efficiency gains, and innovation. We then decide how to best exploit each opportunity and outline the solution, the ROI it will generate and what the development roadmap should look like. 

Systems Integration

We have extensive experience integrating mobile applications into wider software ecosystems and back-office applications, including CRMs and ERPs. We also develop mobile platforms alongside browser-based applications to ensure consistency across mobile and desktop. Our API first approach also allows us to build platforms with powerful data integrations, unlocking unlimited growth and efficiency for your organisation.

Mobile UX Research and Design

Using industry-recognised methodologies we take a comprehensive look at your target users' needs, motivations and objectives. Leveraging qualitative and quantitative data to inform our UX/UI process, we create prototypes and mockups that allow us to fully test, observe and learn how users will respond to your mobile platform. This validated information is then fed into the branding, usability, functionality and design of your mobile app.

Analytics & Optimisation

Our impact doesn't end with launch. We work with clients to understand their business objectives and KPIs, which then inform our analytics strategy and data reporting plans. From day one, we collect meaningful data on your app's performance and user engagement, allowing us to clearly see what's working and what needs improvement. We directly feed this back into feature development and your product roadmap, ensuring that insight leads to action and ultimately impact.

Start-Up App Development

We love working with startups and using our expertise and experience to assist in shaping and moulding the digital direction of breakthrough new businesses. 

We've worked with some of the UK's most exciting mobile-first start-ups, helping them step-by-step to transform their ideas into an MVP or fully fleshed-out product. Alongside providing product development services, we can also support you when it comes to finding and securing funding using our extensive investor network and Ventures programme.

The journey doesn’t end after launch either. Our team works with a number of businesses on an on-going basis to define, design and build new features to drive exponential user and revenue growth.

Supporting material components and native widgets, Google's SDK Flutter offers near-native performance on iOS and Android from a single codebase.



We use Java-based Kotlin as our language of choice to make our Android apps more maintainable, concise and error free.
