    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.

    this app is amazing and really accurate.it blows my mind how accurate it is it has kept.me from looking stupid showing up at the doctor's office when it was something I was able to treat at home.and vice versa I have went to the doctor because it was recommended by ada and was happy I listened. a couple times I have had to redo the assessment a couple times I did not click the right option when it gives you all the options to choose from about your possible problems but great app overall
  • Programmed very well.. but could use some minor improvements Dec 14, 2020

    By Bookworm0917
    I’m diagnosed with bipolar disorder and ada has been able to help me distinguish between when I’m having an anxiety attack or when my muscle aches and pains were more than just side effects of my meds. However, I believe that ada could be improved if we were able to add pre existing conditions to our profiles, in addition to our prescriptions actually factoring into the reports. Am I feeling fatigued because of my meds? Or is it something else? Pre existing conditions and medications can make it that much harder to question if it’s more than a side effect. And especially in the times of Covid seeking medical help is just getting more expensive in the US. But ada has helped me see when I should and shouldn’t go to the doctor (they helped me recognize the symptoms of pneumonia in time for me to get diagnosed before my lungs would be damaged any further than they were). I love this program, I just wish we could add the illnesses we already have and the effects our meds have on us. Of course the devs can’t list every medication, but letting us list the symptoms those meds cause should be factored into ada’s reports. There’s more conditions other than smoking, diabetes, etc that ada currently lists, and I feel the preexisting conditions are very limited. And I hope my thoughts on this are seen by the devs and can be brought into consideration.

    Good app, neads to be able to take preexisting conditions and medications in to account, as well as possibly adding things that run in your family. Ide also like to be able to pick more than one option on pain location without having to click generalized.
  • It’s a lifesaver! Jun 3, 2019

    By froghead*rates
    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!

    So far SO accurate, I’ve researched my symptoms online back in the days of WebMD and the such. I’ve even recently downloaded and chat message connect app with a “real” doctor that also left me very disappointed with the diagnosis and care. However so far believe it or not Ada has been spot on! I find it so helpful to just have some clarity of my own suspicions of what’s going on with me and opening my eyes to things I didn’t consider but make COMPLETE sense. Simple, informative, affective. I’m waiting for my insurance to become active and such through my employment again and it’s helping me SO much to know what to follow up with and speak to my doctor about. Awesome App! Not sure how you’re doing it Ada and team but I REALLY feel you know what you’re doing. So SHOCKED but so PLEASED! Thank you so much again you allay my fears of the worse and educate me on what I wouldn’t have even considered. If you haven’t yet download it and use it, it works!

    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.

  • AMAZING APP Aug 14, 2020

    By AbcdCheif000009947
    I’m 17 and i was diagnosed with lupus almost a year ago, i got bored today and tried filling in my symptoms just kinda as a game, using it like the ackinator app. Within maybe around 8-10 minutes after putting in my symptoms the app said i likely had fibromyalgia but that my most possible unlikely cause was lupus, SLE. I just think it’s amazing that this app managed to diagnose something that took over a decade for my doctors within 10 minutes and it acknowledges that it’s not a completely accurate diagnosis and you should go see a doctor to be sure. I’m not saying to replace doctors with this app, just that before going it could be greatly beneficial to use this app and then ask your doctors about the possibilities of having what it may think the causes are :) overall 10/10 app i’d highly recommend it and the people who made it are amazing at what they do!

  • Fantastic for getting a head start. Aug 25, 2018

    By Robinlovesanime
    This has been very helpful to me. As a woman (and I hate leading a sentence like that), often times internal body pain for girls is written off. I went to the ER 3 times in one day and the doctor kept telling me it was period cramps until the last time I came I was completely immobile and peeing blood every hour. It ended up being a horrible UTI that got out of hand because they brushed it up to mensural pain. This app gives me a start on what kinds of things might really be going on inside my body so I can do research a bit better before getting to the hospital. So the last time I went in with early signs of another bladder infection I was able to suggest they look into seeing if my symptoms were worse than just what they suggested (which surprise surprise, after they found I wasn’t pregnant they chalked it up to period pain)

And I hope my thoughts on this are seen by the devs and can be brought into consideration.

  • Great App (One suggestion) May 1, 2019

    By IEblazed
    I would suggest Ada would have photos in her symptom assessment. I am unaware if it has any capability of doing so if there is I would love to be notified on how to enable the option. But to continue, it would be lovely if her questions about pain had an image to help specify where it is directly pointing at. An example of a sort is if a person was in an important situation (pressuming they hadn't gone to get medical help) and had to evaluate someone of their symptoms to see if it was anything serious. They run into a question that ask if they have pain above the abdomen. If the person is unaware of what an abdomen is then it would lessen the time and make it slightly difficult for them to finish the evaluation. The option for images could also have certain sizes for the red pain marks. It could be more focused if Ada was asking for sharp pain, it could be more spread if Ada was asking for pain all around, or it could be a moderate size to show if Ada was asking for normal pain. Ada's post-evaluation sequence should show specific images and areas for the tumors she suggest that the symptom lead to or the bones that have been affected. Otherwise, the app is great always saved me the worry. (I still seek medical help if I'm sure it's serious or if my symptoms get worse) I recommended the app throughout my family and friends! Continue the great work.

    I love this app and I always think I have some sort of disease so I downloaded this app. It really helps me easily type in my symptoms except for some complex ones and it is like talking to a tiny, portable doctor (not really allowed to say for sure you have a disease which is good) in the palm of my hand! I cannot type in my main symptoms which bothers me but I get passed it and so will you! I prescribe this app to ages 13-99 because of its perspective on sicknesses and the way it says everything so calmly as if it knows you’re already tense when you wake up. Thank you, Ada, I love this app to the design all the way to how you coded it to set a clam atmosphere to the patient.
  • Something that could be added Dec 26, 2020

    By hdbdnnsjs
    I don’t typically leave reviews. And personally from someone who is very sick a lot I love this app but I was diagnosed with Hashimoto’s disease and I kind a wish I could add that to my profile so it wouldn’t continuously give me that so I was just hoping that would be offered here soon because I was putting in my symptoms I’ve been feeling in the past week and it came out to be Hashimoto’s disease which like I previously said I have already been diagnosed I hope they come out with a place you can put what you’ve already been diagnosed with soon....
  • Very Helpful, Calming, A bit odd May 31, 2019

    By FoxGuuurl
    If I could, I would do a 4.5 review. I was nauseous for about a week. And lately, I’ve had anxiety every time I feel a little bit bad. Sometimes, I don’t know what it is, so I check ada for help. It very clearly shows that this is not completely accurate, which is very helpful. It showed me that it’s probably Anxiety, which is calming. My only complaint is that sometimes the answers are weird. And can make me upset more after not knowing what it is. But that’s just a personal thing. Other than that, great app!

    Fair. Need to add more choices for the answers. All things can't be answered with a simple "yes" or "no" format. But other than that, or even in spite of that it is still a pretty good app.
  • Review Jul 13, 2018

    By abk4020
    I feel that Ada used very clear algorithms to determine what the next question should be but there has to be an option for “at times” as a response to a symptom question instead of a “yes, no or idk” response. Also asking the user for another symptom leaves a lot of the onus on the user to highlight or think of another symptom when there should be the option to choose more than one symptom at a time when presented on the screen. Just my 2 cents as a therapist. Oh and ask if a person has type 1 or type 2 diabetes as they are 2 completely different diseases with different origins, “1 “ being an autoimmune disease.
