The app had really useful MCQs and was accurate in the diagnosis process. Best purchase I’ve made for myself! ### 5/5 — Very useful! *2019-11-07, version 3.2* I was looking around for a medical tool that would help me with my studies, and I can’t be any happier that I came across Dem Dx. The tutorial when you first open the app is extremely helpful, and the app is overall very easy to navigate. I definitely learned a lot as well from the different pathways and quizzes. Highly recommend!!! ### 1/5 — Crashes *2019-06-02, version 2.6.2* Crashes right in the middle of MCQs and all progress is lost 😑 ### 1/5 — What the heck!? *2018-10-04, version 2.5.2* When i first found this app i was immediately in love by it, since i am a jr Dr, still need some kind of help getting to my diagnosis, and it was really cool at the begging, but then come the uptates, after i had to buy a subscription to use the pathways and i was annoyed by that, cause it used to be free and now that I actually bought the subscription the app started to crash immediately after buying it!, idk what happen if it’s ocasional or a SCAM, i really hope its not, and will do an update to solve this problem, cause it was not happening 😤 ### 1/5 — DEM DX *2017-05-15, version 1.2.8* Unable to open it. Crashed immediately Hope to solve this problem in your next update, which I hope it will not be after long time. Thanks ## Frequently asked questions about Dem Dx ### What is Dem Dx used for?
