What is Ada Health?
Ada is a symptom-assessment app: it asks questions about your symptoms and gives a report with possible conditions, an estimated likelihood for each, and a suggested level of care. It runs as an iOS and Android app and on the web, and the vendor also offers the same engine to health organizations as Ada Assess.
Who it's for
The consumer app is aimed at lay adults who are concerned about their health; the instructions for use name users 16 and older (guardians may assess younger people) and include elderly people and pregnant women. The vendor also sells to health organizations and partners, and it says Ada is not for emergencies and not a substitute for a healthcare professional.
Pros & cons
Strengths
- Ada's Terms say Ada Assess and the website are provided free of charge with an unlimited number of assessments and reports, and list no paid features.
- The Google Play listing shows no in-app purchases and says the app is free; it lists seven languages: English, German, French, Portuguese, Spanish, Swahili and Romanian.
- The vendor says it is not a diagnosis tool: the instructions for use say it does not provide a final medical diagnosis, and the Play listing says it connects to a CE-marked medical device that cannot provide a medical diagnosis.
- A December 2022 Ada press release says Ada Assess was certified as a Class IIa medical device under EU Regulation 2017/745 (MDR), with TÜV SÜD as notified body. Ada's site also shows ISO 13485 and ISO 27001 badges.
- The instructions for use say a built-in stop ("roadblock") ends the assessment for certain emergencies, such as suicidal ideation or chest pain suggestive of a heart attack.
- The Play listing says users can export past reports to share with their doctor, and its data safety section says data is encrypted in transit and users can request deletion.
Limitations
- Ada says it does not provide a final medical diagnosis, is not a substitute for advice from a healthcare professional, and should not be used in a medical emergency. Its list of conditions is not exhaustive, and the result depends on the answers given.
- The instructions for use say users must be 16 or older (younger users via a legal guardian), while the Terms say 13 or older, with guardian consent under 18. Confirm which applies to you.
- The US privacy policy says people outside the United States should not use the services, and the GmbH (EU) policy governs the app; the pages differ on which entity and rules apply. Confirm which policy applies where you live.
- Ada's privacy policies say data is used to run and improve the services, for research and development, and to build new capabilities, and the US policy allows targeted ads subject to consent and opt-outs. It says information will not be used to train a third-party model, but it does not clearly say whether Ada's own models are trained on user data.
- Ada's pages do not show an FDA clearance. The site's regulatory statements name EU MDR Class IIa for Ada Assess, but the consumer app pages I read did not state a class, and no US clearance is stated. The 15 million users and accuracy claims on ada.com are vendor statements (Reported).
Plans and pricing
- Ada app (consumers): $0. Free on iOS and Android per the Terms and Play listing; unlimited assessments and reports; an account is needed to run an assessment.
