Ada

What is Ada?

Ada is a symptom assessment app from Ada Health, a company based in Berlin, Germany. You answer a series of questions about your symptoms and Ada suggests possible causes along with advice on how urgently to seek care. It is a support tool, not a replacement for a doctor.

Ada is one of the better-known AI symptom checkers. It runs on iOS, Android and the web, and it guides you through a structured interview about what you are feeling, rather than asking you to type a free-form question into a chatbot.

After the assessment, Ada shows a list of possible conditions with an indication of likelihood and a suggested next step, such as managing at home, seeing a doctor or getting emergency care. It also offers short explainers about conditions, risk factors and treatment.

You can create profiles for other people, such as a child or an older relative, and keep a simple symptom log with notes. If you report signs of a serious problem, the app stops the assessment and tells you to contact emergency services.

Ada Health also works with healthcare organizations and life science companies. For individual users, the main product is the free consumer app.

Key features of Ada

• Guided symptom assessment: Asks follow-up questions one at a time, with explanations, diagrams and an "I don't know" option when you are unsure.
• Possible causes with urgency advice: Lists conditions that could explain your symptoms and suggests whether to self-care, see a doctor or seek urgent help.
• Condition explainers: Short overviews of conditions, risk factors, diagnosis and treatment to help you prepare for an appointment.
• Profiles for family members: Run assessments for someone else, such as a child, under a separate profile.
• Symptom tracking: Log symptoms over time with notes so you can share a clearer history with a clinician.
• Emergency safeguards: Stops the assessment and points you to emergency services when your answers suggest a serious condition.
