What is usability testing?

Usability testing means watching real people try to complete real tasks with your product, then fixing what slows them down. It shows where users get confused, stuck or frustrated, and why, so decisions are based on evidence rather than opinion.

How is usability testing different from UI/UX testing?

UI/UX testing is done by experienced testers who check the interface against the design and usability principles. Usability testing involves real users from your audience. Both are useful; usability testing tells you how actual users behave.

How many participants do we need?

For moderated sessions, five to eight participants per user group usually reveal most of the serious problems. Unmoderated tests and benchmarks often use more participants to get reliable numbers. The study planner on this page gives a first suggestion.

Moderated or unmoderated testing?

Moderated sessions are best when you need to understand why users struggle and want to ask follow-up questions. Unmoderated tests are faster and reach more people, and work well for simple, clear tasks. Many studies combine both.

How do you recruit participants?

We recruit people who match your user profile, using screener questions. Where you can share your own customers or user lists we recruit from them; otherwise we use recruitment panels. We handle scheduling, reminders and incentives.

Can you test designs before they are built?

Yes. We test clickable Figma prototypes with real users, which is the cheapest moment to find and fix usability problems.

Do you test mobile apps?

Yes. We test on participants’ own phones where possible, looking at gestures, tap targets, keyboards, onboarding and permissions on both iOS and Android.

Do you include people with disabilities?

Yes. We run accessibility-focused sessions with participants who use screen readers, keyboard navigation, magnification and other assistive technology, alongside an expert accessibility review.

What is the System Usability Scale (SUS)?

SUS is a short, standard 10-question survey that gives a usability score from 0 to 100. It is useful for comparing versions and tracking usability over time.

A study plan, session recordings, severity-ranked findings with video clips and quotes, usability metrics where measured, a prioritised fix list and a debrief with your team.

Can your team watch the sessions?

Yes. Your team is welcome to observe moderated sessions live, and all sessions are recorded for anyone who can’t attend.

How long does a usability study take?

A small unmoderated test can return results in a few days. A moderated study with recruitment usually takes one to three weeks from kick-off to debrief, depending on how specific your users are.

Do you test IoT and desktop products?

Yes. We observe how people use physical devices and their connected apps, and how they work through desktop software workflows.

What does a usability report include?

A usability report includes findings ranked by severity and frequency, clips and quotes from real participants, and a prioritised fix list your designers can work from right away. The findings come from moderated and unmoderated sessions with people who match your users, run against the tasks that matter most to your funnel.

[ Why usability testing ]

Adopt user-focused usability testing for optimal results

UX and usability testing are crucial for mobile, website, and desktop applications. In today’s interface-driven era, software usability testing is as important as development. As a usability testing company, our experts tailor strategies to your application, considering user types, demographics, and key scenarios. We select users, create surveys, and guide them through the process.

[ What we test ]

Usability testing that produces decisions

You get clips, quotes, and a prioritised fix list your designers can work from on Monday. Ten services, each with what we do, when you need it and the problem it prevents.

Moderated usability sessions

Remote or in person

A facilitator sits with each participant, remotely or in the same room, and asks them to complete real tasks while thinking aloud. We see what they do, hear why, and can ask follow-up questions in the moment.

What we test

Tasks and success criteria agreed with you first
Think-aloud sessions with a trained moderator
Remote over Zoom or Teams, or in-person sessions
Every session recorded, with your team welcome to observe

When you need it

When you need to understand why users struggle, not just where.

The problem it preventsGuessing at the cause of drop-offs instead of seeing it

Unmoderated task-based testing

Fast and scalable

Participants complete tasks on their own time with Maze, Useberry or UserTesting, so you get results from more people, faster.

What we test

Clear tasks and questions set up in the testing tool
Task success, time on task and misclicks measured
Screen and voice recordings where the tool allows
Results from more participants in a few days

When you need it

For quick checks, larger samples and simple, well-defined tasks.

The problem it preventsWaiting weeks to learn something a few days of testing would show

Participant recruitment

Your real users

We recruit participants who match your users: from your own customers or user lists where you can share them, or through recruitment panels when you can’t.

What we test

Screener questions based on your user profile
Mix of new, regular and power users as needed
Scheduling, reminders and incentives handled
Consent and data handled with care

When you need it

For every study; the right participants matter more than the number.

The problem it preventsTesting with people who would never use your product

First-click & navigation tests

Can they find it?

Short tests that show where users click first, how they group your content and whether they can find what they came for.

What we test

First-click tests on key pages
Tree testing of your menu and structure
Card sorting to see how users group content
Clear findings on labels and structure

When you need it

Before redesigning navigation or adding a new section.

The problem it preventsUsers who can’t find a feature, so they assume it doesn’t exist

Prototype testing

Before you build

Your Figma prototype tested with real users before a line of code is written, when changes are cheapest.

What we test

Clickable Figma prototypes tested with real tasks
Unmoderated tests in Maze or Useberry, or moderated sessions
Concepts compared side by side
Findings your designers can act on straight away

When you need it

During design, before development starts.

The problem it preventsBuilding and shipping a design users don’t understand

Mobile app usability testing

Touch, thumbs and small screens

People use phones on the move, one-handed and distracted. We test your app the way it is really used.

What we test

Sessions on participants’ own phones where possible
Gestures, tap targets and on-screen keyboards
Onboarding, permissions and notifications
iOS and Android behaviour compared

When you need it

Before launch and after redesigns of key app flows.

The problem it preventsAn app that works in the office but frustrates people on the go

Competitor & benchmark studies

How you compare

The same tasks run on your product and your competitors’, or on your product before and after a redesign, so you can measure progress.

What we test

Same tasks across products or versions
Task success, time and satisfaction compared
Strengths and weaknesses side by side
Benchmark you can repeat later

When you need it

Before a redesign, and to prove that a redesign worked.

The problem it preventsRedesigning without knowing if it is actually better

Surveys, SUS & task success metrics

Numbers to track

Standard measures that turn opinions into numbers you can track over time.

What we test

System Usability Scale (SUS) questionnaires
Task success rate, time on task and errors
Post-task ease ratings
Short surveys and questionnaires

When you need it

Alongside any study, and to track usability release by release.

The problem it preventsArguing about whether the experience is “better” with no numbers

Severity-ranked findings with clips

Ready for action

Every study ends with a short, clear report: what went wrong, how often, how badly, and what to do about it.

What we test

Issues ranked by severity and frequency
Video clips and quotes as evidence
Prioritised fix list for designers and developers
Debrief with your team, Monday-ready

When you need it

At the end of every study.

The problem it preventsA long report nobody reads, and nothing changes

[ Watch, then fix: evidence over opinion ]

Choose the method that fits the question

We use the method that fits the question, from quick unmoderated task runs to full moderated sessions with accessibility review. Every finding looks like the one on the right.

Method	Question it answers	Who and how many	Strengths and limits
Moderated sessions	Why do users struggle?	5–8 participants per round	Deep insight, follow-up questions
Unmoderated tests	Where do users struggle, and how often?	Larger samples, quickly	Speed and numbers, less “why”
Heuristic evaluation	What breaks known usability principles?	Expert reviewers, no users	Fast and cheap, but no real users
A/B testing	Which version performs better?	Live traffic	Real behaviour, needs enough users

Sample findingHigh severity

Issue: Users miss the “Apply promo code” link at checkout
Seen in: 5 of 6 participants
Severity: High · blocks a planned discount
Quote: “I thought there was nowhere to put my code, so I gave up.”
Evidence: 3 video clips, 2 heatmap screenshots
Fix: Show the code field open by default, under the order total

Example only. Real findings come from your own sessions.
