Strengths
- The reference tool for card sorting and tree testing; the analysis visualisations are excellent.
- Tree testing validates navigation before any build effort is spent.
- Well-established methodology support and training material.
- Unmoderated tests and moderated interviews in one tool, so interview work needs no second subscription.
- Card sorting, tree testing and the rest of the method set are included rather than priced as add-ons.
- Recruit from your own users, Useberry's integrated pool, or through Prolific and Respondent.
Limitations
- Narrow scope — it does not do usability testing of interfaces.
- Expensive per seat for occasional use.
- Interface is dated in places.
- Interviews are metered — five a month on Growth, fifty on Business.
- The step from Growth to the next tier is steep: €83 a month to €659.
- Integrations cover design, recruitment, calendar and meeting tools; there is no issue-tracker or chat handoff.
