Free symptom checker that suggests possible causes and a level of care
Buoy Health is a free symptom-checking tool that asks a structured series of questions about how you feel and returns possible explanations along with suggested next steps, such as self-care, a primary care visit or urgent care. It is built as software that helps you navigate the healthcare system, not as a diagnostic service. The company also licenses its technology to health plans and employers. Its interface is plain-language and aimed at people deciding where to go rather than at clinicians.

No. For severe or sudden symptoms such as chest pain, breathing difficulty or signs of stroke, call emergency services immediately instead of answering questions in an app. Symptom checkers are for non-urgent decisions.
The consumer symptom checker is free to use, and you can run a basic check without creating an account. Buoy's revenue comes from licensing its technology to employers, health plans and providers.
