Not super accurate but helps. Biggest problem is locks up and the only thing you can do is close the app up and re-open it. Frustrating, happens too often. 22/3/24 Problems continue with this App. Test the same sample three times. Reading. Varies from 15% to 24% cannot trust accuracy at all. Using a new chip to do the tests. ### 2/5 — Locks up *2023-09-12* I have been using the MyDx One for three years. Not super accurate but helps. Biggest problem is locks up and the only thing you can do is close the app up and re-open it. Frustrating, happens too often. ### 2/5 — App is glitchy but great device *2023-08-01* Like a lot of others on the reviews here I too have had a lot of glitches mainly with the app. Pictures don’t save. Reading other strains results. Can’t email the results or it’ll crash. I can only give 2 stars because of the app issues.. looks like it’s a long overdue problem that needs fixing. This could be a great platform including the expansion cards to test food, water, and air samples. The testing device is great, haven’t had any major issues. Convenient and portable. ### 1/5 — Doesn’t work *2022-12-08, version 4.6.3* The platform has crashed and burned. The device is useless. ### 1/5 — Abandoned? *2022-06-02, version 4.6.3* Feels like this project has been abandoned. App doesn’t seem to work or allow you to register. Spelling errors on the website is an indicator not to spend money this way ### 1/5 — Buggy *2022-04-26* I use this app a lot for my work. There are multiple bugs that are frustrating. One being after you test a flower, it’ll give you the exact same result from a different flower that was previously tested. Sometimes it’ll happen once or it won’t stop giving me that wrong result until I come back after about an hour or so. Another is after testing 4 or more flowers and going back to get the results to email to myself, it’ll repeat the same 6 or 7 flowers scrolling down from the my data tab. This means that I can’t get the other flowers I previously tested since technically I cannot scroll down to extract/ email them. Fix these issues BIG TIME. ### 1/5 — In accurate machine *2021-05-17* Do not buy this machine they are so inaccurate and they won’t give you a refund. Please do some research on it before buying. I just wasted $1600AUD ### 5/5 — The Biggest Scum *2021-04-21* These people stole my money and never shipped me the unit, and didn’t answer the email ### 5/5 — Amazing product *2021-02-19* The product is high quality. Works very quickly. Great for information from multiple facets. Would recommend to anyone looking for more information into what they are putting into there body. Would be useful for police to measure cannabis in reckless drivers. ## Frequently asked questions about MyDx One ### What does the MyDx One app do?
