Last updated: May 6, 2026
SymptomSignal does not provide medical advice, diagnosis, or treatment. Anything you see in the app — including AI-generated guidance, possible conditions, or suggested next steps — is informational and never a substitute for evaluation by a qualified clinician.
If you are having an emergency
Call your local emergency number (for example 112, 911, 999, 119, or 000) right now. Do not wait. The app surfaces local numbers when red-flag symptoms are reported, but it cannot replace immediate human help.
Red-flag symptoms — seek urgent care
- Chest pain or pressure, especially radiating to arm or jaw
- Sudden weakness, slurred speech, or facial droop (possible stroke)
- Severe difficulty breathing
- Severe allergic reaction (swelling, hives, throat tightness)
- Heavy bleeding that won't stop
- Signs of severe dehydration in an infant or older adult
- Thoughts of harming yourself or someone else
Regulatory status
SymptomSignal is not a medical device and is not registered as such with any regulatory authority. It is a public-health signal-detection tool intended to (a) help everyday people decide what to do next and (b) help public-health teams spot unusual patterns earlier.
AI limitations
AI-generated guidance can be incomplete or wrong. Confidence scores reflect the model's calibration, not clinical certainty. Never make a treatment decision based on the app alone.
