Test with the people your product is for, not the people who are easy to find.
In a review of 68 usability studies of self-care health apps, most left out everyone over 65, and many didn't record ethnicity or income at all. We give you matched members who live with the condition, profiled on age, income, first language and more.
For product and user research
You send us the screener, or we write it with you. We invite matched members and they come into your tools: a prototype link, an unmoderated test, a survey, a moderated interview on your call software. When you run the session, the recording and the notes are yours. £120 per completed session, including the member's pay and a replacement for a no-show, so you pay for completed sessions, not invitations. Because members answer within hours to days, first sessions are usually within a week of your screener being agreed. Members can also use your app for a week or two and keep a video diary; you get the findings, never the recordings.
For evidence and regulatory
The report describes who took part, broken down by age, sex, ethnicity and deprivation, what they raised, what you changed and what you didn't, written for the user involvement and health inequalities questions in your NICE evidence standards submission and DTAC. It comes as a dated, version-numbered document you can cite. It's written for two places: the NICE evidence standards framework's design standards on acceptability to the people the technology is intended for and on health and care inequalities, and the usability and accessibility section of DTAC, which asks whether you engage users in developing the product, how, and whether you test usability with them.
Accessibility
The panel doesn't yet hold disability or assistive technology use as standing fields. We screen for them on request and tell you the count before you pay, and we're adding both to the profile survey.
