Usability Testing London

Real user insights within 7 days

Trusted by Amazon, Microsoft, BBC — and major UK retailers — for mobile & digital journeys.

Why Apps and AI Features Fail Without Testing

  • Users don't trust it → AI features feel like a black box
  • Users don't understand it → confusing journeys cause drop-off
  • Users don't adopt it → if the first experience is poor, they never come back

That's why User Testing with real people before or after launch is critical.

For Product Teams & Decision-Makers

You're under pressure to deliver results — whether that's a smooth launch, higher conversion, or proving an AI feature works in the real world.

Our usability tests are designed for busy teams and leaders like you:

  • Fixed price, no surprises
  • Clear deliverables within 7 days of recruitment
  • Trusted by Amazon, Microsoft, and the BBC

Give your team the confidence to launch and optimise with evidence, not assumptions.

Will Your Users Trust and Adopt Your AI?

Mobile first Usability Testing Session

AI creates new challenges that go beyond standard usability:

  • Trust & Transparency → do users believe the AI's recommendations?
  • Clarity & Explainability → do they understand how it works?
  • Adoption & Retention → will they come back after first use?
  • Reliability & Confidence → do users feel confident relying on the AI?

Our AI Product Validation Testing focuses on exactly these issues — helping London teams launch AI features that people actually use.

Frequently Asked Questions

Are the sessions remote?

Yes. All usability tests are run as remote moderated sessions. This allows us to recruit real users faster, at lower cost, while still giving you the same level of insight.

Who are the participants?

We recruit real people from your target audience. For most consumer apps and websites, this is included in the testing price. If your project requires specialist or hard-to-reach users (e.g. doctors, financial advisors, enterprise IT admins), we can recruit them too — there may be additional costs, but we'll always confirm upfront.

How long are the sessions?

Core: 30–40 minutes per user (rapid, focused).
AI: 40–60 minutes per user (adds time for trust & explainability).
We’ll recommend the right length based on your goals.

How much does it cost?

Our fixed-price tests start from £4,950 for a Core Usability Test and from £6,950 for an AI Product Validation Test. Both include recruitment, incentives, moderated sessions, recordings and a prioritised report delivered within 7 days.

How quickly can we start a project?

We can usually begin within 1-2 weeks, depending on participant recruitment. Our team will confirm a timeline as soon as you book your test.

Why only 5 participants?

Five users are enough to uncover the majority of usability issues. This is a proven industry standard, giving you the fastest insights without wasted spend. If you need more users or additional journeys tested, we can expand the testing.

Do you only test apps?

We're mobile specialists, but we also test websites, SaaS, ecommerce, and AI features. The testing format works across all digital products.
