Abstract
This software is the very first publicly available smartphone application for a valid, scientifically proven lie detection paradigm: the response time Concealed Information Test, which aims to reveal whether or not a certain information detail is known to the tested person. Presently, this application is primarily intended for research purposes, providing a ready, easy-to-use, and completely free option to perform this test in flexible settings (e.g., in large groups or remotely). In the future however, the application could also be field-tested and verified for eventual real-life use by appropriate investigative and other authorities all over the world in various critical scenarios, especially where desktop computers are not available, limited, or impractical.
