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.
EyeScan Solo
Read full descriptionHide full description
EyeScan Solo is a 1st line defense against substance impairment, designed for employee screening in high-risk workplaces like mines and manufacturing floors. It uses artificial intelligence to screen employees rapidly and objectively, improving safety by reducing human error and bias. Employees complete a 6-second eye-tracking scan, following a dot on the screen while AI analyzes hundreds of variables to detect potential impairment. EyeScan Solo is a preliminary screening tool that flags potential issues for further testing. All screenings are supervised, and employees flagged by the scan undergo confirmatory tests with validated methods according to internal policies. Capable of screening thousands of employees daily, EyeScan Solo significantly improves safety protocols and reduces the risk of accidents. Important Disclaimer: EyeScan Solo is not a diagnostic tool and does not replace medical testing. It complements traditional methods which is clearly stated in our terms and conditions. The app supports safety processes by providing an initial screening step, followed by validated confirmatory tests for flagged individuals. EyeScan Solo promotes safety and wellbeing in high-risk workplaces by providing an efficient, non-biased, and user-friendly screening tool, placing safety at the heart of your brand.
