Ratings and ReviewsSee All
I don’t usually leave reviews, but this app has been incredibly helpful for me. For some reason this past year I went through a few rough illnesses, one in particular that no one was able to accurately diagnose. I was in the worst pain I have ever been in and everyone kept telling me that it was nothing, or that they weren’t sure what was causing it. With nowhere left to turn I decided to downloaded this app put my symptoms in to try and find out something about what might be going on. The app makes it clear that this is not a true medical diagnosis and that you should always seek help from a doctor in person when you can, but even still it came up with a few possible diagnoses that I was curious about. Nearly a week later, when my condition finally got bad enough a doctor was able to figure out what was causing the pain and it turned out to be the same diagnosis this app suggested as the most likely cause of my symptoms. Since this incident I have used the app a few more times and it has been very helpful and incredibly informative.
It’s a lifesaver!
For someone like me, who’s always worrying about having the most major sickness when I only have small symptoms, ada is a lifesaver. Anytime you feel sick and anything hurts, you can use ada to type your symptoms down and answer a few questions about how you’re feeling. This includes things like, “how are your symptoms changing over time?” and if you have any other symptoms. It lists a number of different things you could have, some of them are less likely then others. You can read about the sickness and it even gives you remedies to treat it. This app has helped me a number of times, and it’s also very easy and simple to use. You can get a symptom assessment done in only a few minutes because the questions are simple and straight to the point. Still, you should always see a doctor if you’re worried, and I’m happy to say ada does also remind you that. I have nothing bad to say about this app at all. It even checks up on past symptom assessments to see if you’re doing okay!
This app is a very useful, innovative, and accurate app. This is very useful for anybody in their daily lives. There are many symptoms to choose from, being simplistic or incredibly diverse in nature. Something that I enjoy about this app is that it does follow-up questions when you enter the app again. Always seeking to improve itself, it asks for your input as well as a doctors diagnosis if one has been determined. Another great feature is a comparison to others with similar symptoms. I typed in all my symptoms for the common cold, and it told me that eight out of 10 people with my similar symptoms had the common cold. Yes, while The rhinovirus is a very simplistic one, I have entered more complex symptoms for different cases, and have found great results. When the results were undetermined, it asks for input, in order to better improve itself. Overall, a very spectacular App that shows great signs of one day becoming something that every household Will have, in the world.
