Popular checks, explained
🌡️

Fever

Is it just a bug, or a warning sign? Nidanix weighs duration, temperature and accompanying symptoms.

🤕

Headache

Tension, migraine or something that needs review — with the red flags that mean don't wait.

🩹

Rashes & skin

Add a photo; the on-device quality check helps a doctor see clearly if a consult is needed.

🫁

Cough & breathing

From a common cold to signs that need urgent care — triaged safely, never alarmist.

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.
