The MyDx (My Diagnostic) Application offers a personal journal of your experience with everything you eat, drink and inhale, including Cannabis (aka Marijuana).

MyDx offers consumers the ability to detect chemicals we consume every day and track how those chemicals make us feel and what they helps us relieve, so we can find the food, water, air and cannabis strain that works for us.

This application also controls the revolutionary MyDx Analyzer (based on NASA funded technology), which will help you trust and verify the chemical composition of what you eat, drink, and inhale.

The MyDx app can be used in conjunction with the MxDx chemical analyzer, or can be used stand-alone.

MyDx offers 4 Applications in one App:
CannaDx - Find a cannabis strain that works for you based on its chemical profile
OrganaDx - Test for pesticides in food and help determine whether it is Organic
AquaDx - Tests for harmful chemicals in water, including heavy metals
AeroDx - Test your air quality for volatile chemicals, as well as temperature and humidity

Start using our cutting-edge CannaDx application to discover how the Total Canna Profiles of different cannabis strains influence patient ailments and feelings.

Innovative product idea looking forward to future development

Similar to how I track psychophysiological responses to the food I consume it’s nice to have data on the things I inhale and drink as well! Great idea and user friendly.

I don’t like the customer service.

I have had my Dx tester for some time. I have had numerous problems with it. I have had a malfunction with the first on I bought and I got the growers package with all the extra stuff. And when I got my replacement Dx tester it was used!! I called the company up and they said it’s his personal machine that he sent me? Why the hell would I want a used machine when I’m buying a new one? Then to top it off the guy don’t want to send me a new one like witch I should have gotten when the first machine stoped working. Now to this date there still not calling me back. MyDx tester don’t even connect any more now I have an extremely expensive plastic paper wait that the company don’t want to come good on. I’ll never recommend this place to anyone. This company is a joke!!!!! From Christopher Sockbeson an unsatisfied customer.

Great idea, cool product, horrible app

I love MyDx machine and I own it. However the app accompanying the device is one of the worst mobile app I have ever seen.

App is useless on iPhone SE. Crashes whenever I want to perform test, crashes when I want to email report.

iPad version can only perform test, but often does not detect device and I have to reboot device and restart MyDx app.

App lowers the THC level when searching for similar strains.
App list your data in a nonlogic way.

As a user I have no choice than to pray that at least I can perform test.

And company support? Don't even try. They reply on avg. in three weeks and more. And they want me to contact someone else inside company,like they can't talk to each other.

I hope app get better and as a former mobile app UX designer I am more than happy to help.
