Usability testing

Usability research tells you what to build, and for whom.

We run test sessions of your product with real target users, analyse every interaction and capture biometric signals to show how people truly respond, not just what they say.

What we offer

Find out who your users are, and what they need.

Wanting to understand who your users are? Usability research opens a knowledge base of information on what to build, and for whom.

  • User research

    A series of test sessions with real users. We analyse their interactions and extract the data that reveals more about your product and your audience.

  • Biometric capture

    Eye tracking, facial expression and physiological signals reveal the emotional responses people feel while using your product.

  • Software and hardware

    From apps and websites to physical devices, we test whatever your users will hold, tap or look at.

How a study runs

Four steps from question to answer.

  1. 1

    Plan

    We agree what you need to learn, which tasks to test and who your target users are.

  2. 2

    Recruit

    We find participants who match your audience, from our own panel or beyond.

  3. 3

    Observe

    Participants use your product while we record interactions and biometric signals.

  4. 4

    Report

    We turn the data into clear findings and prioritised recommendations.

What you get

Evidence you can act on.

No hundred-page reports nobody reads. Clear findings, backed by data, with the next steps spelled out.

  • Recordings and highlights of every session
  • Heatmaps and gaze paths from eye tracking
  • Emotional and physiological response timelines
  • Task success, time on task and error rates
  • Usability issues ranked by severity
  • Recommendations mapped to our four principles

Questions

Frequently asked.

Software and hardware alike: websites, mobile and desktop apps, VR experiences, prototypes, and physical devices or packaging. If a person will use it, we can test it.
