Usability with SUS

SUS usability is a free app helps you perform system usability scale (SUS) tests on users. It not only gives the tests, stores the results it also computes the score.

The system usability scale (SUS) is a simple, ten-item attitude scale giving an overall view of subjective assessments of usability of an app. Developed by John Brooke at Digital Equipment Corporation in 1986 as a standard ISO tool to be used in usability engineering of systems such as websites,apps and software. SUS is a basic tool used by interaction designers around the world.

If you are a UX( user experience) expert, a user interface designer, an interaction developer, website or just an app developer you can use SUS tests as one of your basic tools to evaluate the effectiveness of your app,software or website. If you introduce new features and fix old bugs you can track if this has improved or decreased the usability using SUS.
