Questions, answered
What symptoms can I check?
Almost anything you'd ask a doctor about first — fever, cough, headache, rashes, stomach pain, fatigue and far more. Describe it in your own words.
How long does a check take?
Usually under two minutes. You describe how you feel, optionally add a photo or voice note, and get a clear result in seconds.
What do the colours mean?
🟢 Green is self-care, 🟡 amber means see a doctor soon, 🔴 red means urgent. They appear only for medical risk, so the meaning is always unambiguous.
Will it tell me exactly what's wrong?
No — it shows likely possibilities and what to do next, then connects you to a verified doctor for the final word when needed.
