Ada Health is a free AI symptom checker app. You answer simple questions about how you feel, and Ada suggests possible causes and what to do next, such as self-care, seeing a doctor or getting urgent help. It is free for users on iOS, Android and the web.
What is Ada Health?
Ada is a health app that uses AI to assess symptoms. It works like a chat with a doctor-style interview: it asks follow-up questions based on your answers, then gives a report with possible conditions and advice on where to get care.
Ada was built by doctors and scientists and is certified as a medical device in Europe. It also offers a medical library and works with health systems and insurers. Ada does not replace a doctor, but it can help you decide what to do next.
