UX Design Services.

As a leading UX design agency in London, UX design is at the heart of every app or web project we work on. However, we can also provide user research, design research, UX design, UX testing and conversion rate optimisation independently of our development services.

UX Audit.

If your application or website is underperforming, we can conduct a UX audit looking at personas, user journeys, conversation rates and sentiment. 

User Research.

We have conducted user research for some of the biggest organisations in the world, interviewing, surveying and analysing data. 

UX Design.

We design in a user-centric fashion, using the data we’ve collected during our research. We iterate rapidly using feedback from real users.

UX Testing.

We test our designs with real users and iterate based on feedback. We can conduct both quantitative and qualitative testing and provide evidence for making changes. 
 

Partnering with your developers.

We produce web and mobile apps in our UX design studio, which means we have a deep technical understanding. If you have in-house developers, or an existing development partner, and need a user interface designed for the application they are creating, then we are your agency.

Beyond wireframes.

We can go beyond UX wireframes, mockups, and static designs and produce standards-compliant HTML toolkits, complete with documentation for you developers to utilise. This guarantees the final quality and reduces developers misinterpreting implementations. We can also produce full style guides, brand guides and branding, to help you take your application from a codebase into a fully-fledged product.

Our UX design projects.

User research and UX testing.

Over the past 24, our London UX design agency has developed various methods for user research and UX testing:

Connect with us

Stakeholder research

We like to include both internal stakeholders (your team) and external stakeholders (your users). Stakeholder research allows you to gain insight into requirements, pain points, brand as well as providing a sense of buy-in from participants. We can do this through interviews, focus groups and surveys. We also conduct a range of desk-based research. 

Tree testing

A staple in our UX design studio, tree testing is a great way to test information architecture (IA) both in terms of hierarchy but also the naming of things. Bad IA will mean users struggle to find the answers they need. We use an online tool, which allows us to gather feedback from a wide group of participants easily. 

First-click testing

First-click testing allows us to rapidly test the usability of wireframes and page layouts. We use an online tool which allows us to set tasks for participants to complete (such as clicking on a contact button). We can then analyse the results and make recommendations. 

Moderated usability testing

Frequent usability testing with small groups is the best way to identify and resolve usability issues. We have various ways of setting up these tests and working with small groups to test, iterate, and test again.
