Digital Solutions For Every Device

Android

Optimised for optimum native performance on Android OS, we take advantage of the latest Google technologies 

iOS

From Dark Mode to Augmented Reality, we build up the limit of what’s possible with Apple’s rich native ecosystem

Flutter Development

Using Google’s flagship SDK Flutter our team are able to deploy cutting-edge mobile apps for both iOS and Android from a single codebase

Enterprise App Development

Our team is well versed in tackling regulatory requirements, security standards and working with multiple stakeholders to truly understand business objectives and processes.

Alongside delivering standalone native apps, our mobile app developers also work with organisations to create apps that are deeply integrated into wider web applications and software platforms. Our API-first approach allows us to develop rich software ecosystems that seamlessly work together.

We like to get involved as soon as possible and are happy to work with you as the specification is being produced to lend a helping hand in defining requirements.

Solutions Across the Mobile Ecosystem

BESPOKE APPLICATION 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: its 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 mock-ups that allow us to fully test, observe and learn how users will respond to your mobile application. 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 ongoing basis to define, design and build new features to drive exponential user and revenue growth.

INNOVATE FASTER

By clearly understanding your product roadmap and commercial objectives, we always investigate, prioritise and deliver the features that are going to leave competitors racing to catch up. Our focus is on getting you exactly where you need to be in the fastest, simplest way, not maximising our build times or bloating budgets.

We identify clear opportunities for businesses to improve their bottom line through the development of new mobile-focused customer propositions. We turn mobile app product and service ideas into tangible applications that are optimised for profitability and on-going performance.

Our Industry Expertise

Fintech

Fintech apps have democratised access to financial services, but building them correctly isn’t an easy task. With deep expertise in security, third-party integrations and regulatory compliance, we build FinTech apps that delight users and drive forward digital services. 

Healthcare

Whether you’re a healtech start-up embarking on the journey to develop your first app or an established organisation looking to deliver a better mobile experience, we understand what it takes to deliver technology that genuinely changes lives.

Shared-Economy

Retail

From mobile eCommerce to accurately managing inventory, mobile apps can be leveraged by retailers to improve customer experience and organisational efficiency. We help retailers uncover and deliver the mobile-first strategies that will make an impact.

Our Platforms

Native App Development

The term native app development refers to building a mobile app exclusively for a single platform using platform-specific development languages such as Java, Kotlin or Swift. We can help you build optimised native apps for iOS and Android utilising the latest platform features and device functionalities.

Cross-Platform/Hybrid App Development

Cross-platform development, also known as hybrid development, enables us to build a single application that can run on various operating systems, instead of developing different versions for each platform. We built some of the UK’s first commercially available cross-platform apps and continue to deliver exceptional cross-platform experiences.
