DRUID is a test for personal and workplace use that measures impairment of cognitive and motor functions. Users chose between either the 1-minute Rapid Druid Test or the 3-minute Benchmark Druid Test. Start your free 14-day trial today. DRUID applies neuroscience research to bring you a sophisticated tool that detects and measures cognitive and motor impairment from any cause, including from cannabis, illicit or prescription drugs, alcohol, fatigue, illness, chronic condition, concussion, severe emotional stress, or injury. Currently available for all smart phones and tablets, DRUID operates like a video game but with each use records hundreds of neurophysiological indicators. Are your employees fit for duty? A version of DRUID that includes management controls is also available for the workplace. Impaired employees, including those under the influence of alcohol or drugs, have slower reflexes and impaired balance. Impaired physical coordination, mental acuity and decision-making results in inefficient or incompetent work, reducing productivity and exposing employees and co-workers to far greater risk of injury or even death. Please note DRUID App is a utility application. DRUID app is not a medical app.
