I like the ability to use the app on my phone as well as my computer. The user interface is easy to use and the app is easy to navigate. I wish that the app had more features, however, I do not find this to be a problem. It is a very useful tool for drug testing. This app is very easy to use and the customer service is amazing. I have been able to use the app for over a year now and have never had any issues. There are not many problems that I have faced with this program. It is a great drug testing tool and has made my work much easier. I highly recommend this program and would definitely use it again. We use this app to drug test our employees as well as our students. This is a very easy app to use and the customer service is great. This is a great company to work with. It is user friendly, easy to set up, not expensive compared with other options out there. We like that you can see when someone tests positive so we are able to contact them quickly instead waiting till they test negative which gives us more time to work through different scenarios before getting back in touch. There isn't much I dislike about it but maybe if we could get notifications from our website as well. This has allowed me to stay organized without having multiple spreadsheets all over my desk!
