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. ## Key features - Cognitive and motor function assessment - 1-minute Rapid Test - 3-minute Benchmark Test - Detects impairment from various causes - Neuroscience-based technology - Workplace management controls available ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | DRUID Premium | $14.99 | one-time | | DRUID Premium | $1.99 | one-time | ## Recent user reviews (10 of 34) All indexed reviews: https://appshunter.io/ios/app/druidapp/id1107595146/reviews.md ### 5/5 — Good indicator *2026-01-28, version 3.5.1* Once you get a baseline and get the hang of it, the app does an amazing job of showing if you are offbase. I tried it after a few drinks and my scores got worse. Great safety check if ur doing anything dangerus ### 3/5 — The idea seems nice *2024-12-17, version 3.3.6* The idea to have a mobile app to test impairment seems nice but I'm not paying a monthly fee for something that says I'm impaired if i don't take any cannabis and if I've taken cannabis it says I'm normal I can't trust this information when I my self the user knows I'm impaired when the app says I'm not even says I'm better than 25% of the people my age either people need to get out and be active or this app isn't accurate enough track if I'm impaired or not. ### 5/5 — Notably consistent… *2024-11-13, version 3.3.3* I have been testing out the Druid App for a few months… it confirms when I know I’m tired. Or overworked. If I have a small headache… or maybe more beer than is good for me…;-) This app also let’s me know when I’m in my good zone to perform as an athlete. I think testing performance potential using this app could really help indicate if a rest day is necessary, or if it’s time to GO!!!! ### 2/5 — First time testing *2024-10-16, version 3.3.0* Stone cold sober for over 48h. Tested to get a baseline. My baseline is at like 53. Something is not right. ### 5/5 — Great App *2024-03-19* I find this a very useful app and quick and easy to use. It is very useful to test for impairment due to not just alcohol or drugs, but tiredness. Especially useful if planning or during a long drive. I have had great support when I needed it and fully recommend this app to everyone. I also like the science behind its operation! ### 4/5 — Trying it out *2024-02-14, version 3.1.8* This looks really interesting. I'm not sure I would rely on this for if I drive or not. I'm on medical Marijuana but I always wait 3-4 hours after I vape before I drive. Thankfully I only have to drive 1-2 times a week for very short distances. I'll take the tests at various times to see my score. ### 5/5 — Amazingly accurate *2023-01-04, version 2.7.4* I have been using the app for over a year now.It worked like a charm whenWe first used it for our machine shop. They've made some additional improvements and the short version has made a big difference with our morning routine. ### 1/5 — 1 star may be changed to higher but… *2022-11-06, version 2.7.4* I have yet to start the test but the last test indicates to stand on one leg. As a paraplegic I’m unable to to that part. I’m not sure what test selector is since I’m not allowed to access it until I perform at 3 test. Is there a different question after the 3 questions have been answered for persons with physical abilities or lack of? Thanks ### 1/5 — App is broken *2022-06-21, version 2.7.1* Purchased App and even after upgrading to the paid version it wont load or work ### 4/5 — Update of my review *2021-11-30, version 2.4.9* Druid staff did get back to me and they were extremely helpful. There was some confusion that has been since resolved. I will return to using this app because it is exactly what I need. ## Frequently asked questions about DRUIDapp ### What does DRUIDapp do?
