Head to head

Symptom Checker Accuracy & Detail edge: AdaR1R19R22R40
WebMD WebMD's symptom checker is often criticized for being too general, providing far-fetched results, or failing to recognize specific inputs R1. Users report it frequently suggests they are 'dying' for minor symptoms or gives irrelevant diagnoses like 'grass allergy' for multiple concerning symptoms in a child R1R40. Some users also find it fails to define simple terms or provide information on specific test results R19R22.
Ada Ada's symptom checker is praised for being generally accurate and helpful in identifying what might be going on, often aligning with eventual diagnoses R77. Users appreciate that it asks good questions and provides statistics on likelihood rather than just a diagnosis, which helps manage worry R71R99. However, some users find it too limited for chronic illnesses or specific rare conditions, and recent updates have made it less user-friendly .
Ease of Use & Reliability tieR3R6R7R8
WebMD WebMD users frequently report significant technical issues, including the app not opening, slow loading times, and crashing R6R8. Many also experience problems with account management, such as inability to save personal information, update profiles, or change passwords R3R7R12. The user interface is described as clunky, sloppy, and hard to navigate, with a lack of Face ID .
Ada Ada generally receives positive feedback for its user experience, with many finding it a great tool . However, recent updates have introduced issues, making it difficult to use, harder to navigate, or causing login problems R72. Some users also dislike the text-based symptom input and the repetitive pregnancy questions .
Features & Content tieR2R5R11R17
WebMD WebMD offers medication reminders, pill identification, and general medical articles R2R5R11R17. However, medication reminders can be buggy, automatically marking doses as taken or having unwanted notifications R18R21. Users also report issues with adding/deleting meds and a desire for features like a vaccination logbook or calendar view for medication tracking . Some useful features, like the allergy tracker, have been removed .
Ada Ada's primary feature is its symptom checker and diagnostic tool R83. Users appreciate its ability to track symptoms and provide a reference for past occurrences . However, it lacks features for inputting pre-existing conditions, which can lead to less accurate or relevant questions . Some users also note the absence of an iPad version and the irresponsible inclusion of a BMI calculator .
International Relevance edge: AdaR54R57R60R72
WebMD WebMD's medication database is primarily for the US, making medication reminders unsuitable for users in the UK and Europe R54R57R60.
Ada Ada has some users in the UK and GB, but reviews do not specifically highlight international database issues for medications, though some general usability issues are reported by GB users R72. There are requests for Arabic language support .
Pick WebMD if

you need a general reference for medical conditions and drug information, and are willing to tolerate frequent technical issues and a less precise symptom checker R2R5R11.

Pick Ada if

you want a symptom checker that generally provides more accurate and contextual diagnostic insights, helps track symptoms, and aids in deciding when to see a doctor, even if you encounter occasional login or navigation issues R71R77R83.

Evidence note: Both apps are free to download, so there is no free-vs-paid asymmetry to consider. WebMD has a significantly larger number of reviews, which may contribute to a higher volume of negative feedback regarding technical issues. Ada's recent negative reviews often highlight issues introduced by updates, suggesting a potential decline in user experience for some.

  1. [R1] WebMD 2/5 · US Why am I always DYING?: So I have used this app for many years and when it tells me I’m dying or tells me my kids are dying I delete it!! But I am having some very troubling symptoms so I thought I’d try it again! I’m not dying, but it’s not recognizing the answers to the questions it asked! I’m having abdominal pain and I marked the box that says prior appendix surgery, and then when I went to go
  2. [R19] WebMD 1/5 · US Failure to define: I went to WebMD for a simple definition of “Dyslipidemia”. The result was a blank screen. I had to Google it. I had always used WebMD for med info because I trusted it, but I guess that won’t always work now.
  3. [R22] WebMD 1/5 · US Glucose Testing Results: My glucose test results was 104 slightly out of range on the high side. I signed up for WebMD to learn more about the glucose test and how to interpret the results and got no information about the test or how to understand the results. I am deleting this app because my very first time in using the app it delivers zero information.
  4. [R40] WebMD 1/5 · US Very Narrow Symptom Checker: If you have ONE symptom, this app may help you. If you need to include several symptoms for an illness, it gives you results for only one symptom. For example, a very young child with several concerning symptoms, rash/fever/pain, it gives you you “grass allergy,” or “injury”, or “eczema”. And the answers are common sense that you already would have ruled out.
  5. [R3] WebMD 3/5 · US “Save your sex for faster symptom checker”: The app will not save my sex! Bug. Please fix. Thanks
  6. [R6] WebMD 3/5 · US Won’t always open: I love this app and have used it for many years to track medication and check symptoms, but it is getting really frustrating. That half of the time I try to open it it won’t open. Please fix this!!
  7. [R7] WebMD 1/5 · US Not worth my time!: I received a security alert that my data may have been breached and was advised to change my password. Sounds reasonable except WebMD’s systems don’t actually work. This issue has been ongoing since at least mid-2025. Any attempt to update account information results in an endless spinning cog that never completes. I tested this on: • WebMD’s website (Safari and Firefox) • T
  8. [R8] WebMD 5/5 · US Slow loading: I love this app. I use it every day for my reminders and notifications. The articles are also helpful ind interesting BUT when opening the app it loads slowly. Hope it can be fixed 🤞🏼
  9. [R2] WebMD 4/5 · US Very helpful go to references: I find this very helpful for quick research on my medical conditions. Seeing a dr for every little thing is unproductive.
  10. [R5] WebMD 5/5 · US WebMD: An excellent medical site that explains in lay terms medical diagnoses and treatments. The explanations are geared to patients and give information that is aimed at a layperson.
  11. [R11] WebMD 4/5 · US Healthy dad wanting solid medical info: WebMD is a trusted site with credible, clear, and helpful information for me and my family. I appreciate the lack of hyperbole, direct information, and that it doesn’t always have an answer. It reminds me that it’s a resource but not the end-all/be-all for everyday medical issue questions.
  12. [R17] WebMD 4/5 · US My aid: I have been using WebMD for several years now. I have daily medications that I take once or twice a day. And it always reminds me and has descriptions of medications, in detail, if I have questions.
  13. [R54] WebMD 3/5 · GB Okay, but...: ... not so good for the UK market. When I saw that this app had medication reminders and also for the Apple watch, I thought great I'll have that. Four of my med's however aren't listed as the drugs database is for the US. So the one thing that sold me one this app made it unsuitable for me.
  14. [R57] WebMD 3/5 · GB UK and Europe: Please could you include UK and European medication names in database as unable to enter medicines on reminder
  15. [R60] WebMD 3/5 · GB Love the new look but....: Still no support for the UK?really??
  16. [R72] Ada 3/5 · GB New Update: Prior to the update I found this app quite helpful. The new update has made it difficult to use, harder to navigate and information harder to find :(
  17. [R71] Ada 5/5 · US Game changer for worrier: I love this app for its ability to help me know how much to worry about symptoms and those around me. The statistics are really meaningful as it says how likely things are instead of a online search saying something without context. I know it’s not perfect but it has helped significantly in my understanding of my symptoms and health.
  18. [R77] Ada 5/5 · US Helpful!: Always VERY accurate for what I’ve put in, even a deviated septum which I ended up having
  19. [R83] Ada 5/5 · US Keeps you informed: I love this app because it helps me decide when I should go to the doctor. I understand it’s no substitute for medical attention, but it definitely helps hypochondriacs like myself make better decisions.
  20. [R99] Ada 5/5 · US Ada has always helped!: As in most cases, it has led to getting better, either by waiting it out, calmly, or by getting to a Doctor sooner than later. Ada opinions matter! Questions are almost always thought provoking, leading to an accurate decision (my “should I stay or should I go!)!
  21. [R95] Ada 4/5 · US Helpful: I really enjoy using this app… I find it very helpful for getting information on basic medical issues, but you have to remember it cannot do a medical diagnosis.It has definitely help me uncover things to discuss at doctor appointments. The app is limited. Ann does not allow you to notate what diseases you are suffering from or ailments you are suffering from because of other diseases…
  22. [R119] Ada 5/5 · US Excelente: Es de gran ayuda, ya que da una idea de que puede ser, pero siempre aclara que se debe consulta a un especialista.
  23. [R12] WebMD 3/5 · US Won’t update personal info in profile: When I try to add or edit my personal profile it will not stop loading and doesn’t update.
  24. [R18] WebMD 3/5 · US Medication Reminders: The medication reminders will automatically move on to the future if you are an hour behind in taking the medication. You have to be really careful or you will end up “Taken” a medication that it is not time for. There is no way to undo the error. The app then becomes absolutely pointless for the medications for the remaining of the day. I’m only giving this app three stars b
  25. [R21] WebMD 3/5 · US I like the app.: I like the app but I don’t love it. The medication reminder needs to have a different notification tone from other apps to make it stand out. It also sends me a ton of notifications that I don’t want even tho I have them turned off. I only want med reminder notifications. Please fix. Otherwise, the app is great. I like pill identifier, symptom checker, as well as that I can save
  26. [R23] WebMD 4/5 · US Organized: It helps me stay on time with my medication with reminders.
