How much does the K Health symptom checker cost?

The K Health symptom checker is free in our app. If you need to see a doctor, it will cost $19 flat fee, or you can sign up for unlimited virtual care for $9/month.

How do I use K Health’s symptom checker?

It’s easy! The first step is to download the K Health app. Then, create a profile with your personal information, and click “Check Symptoms.” The app will ask a series of questions to determine what your symptoms mean. Then, you can text with a doctor to get prescription treatment if needed.

What’s the difference between a symptom checker and Googling your symptoms?

In short, a lot. K Health’s symptom checker is fueled by medical insights from real people like you, giving it the ability to provide personalized health information and diagnoses. Googling your symptoms is the opposite of personal: you can only receive generic health information, not personalized health answers.

What is the best symptom checker?

There are many different symptom checkers available online, but not that many are reliable. At K Health, we provide users with an AI-fueled symptom checker that evaluates symptoms with 98%+ accuracy, based on medical insights from some of the biggest health systems in the world – Maccabi of Israel and Mayo Clinic of the United States.

No more waiting rooms

We’ve redesigned the visit and turned it into an ongoing conversation that feels like texting with a friend. You don’t need to schedule an appointment and pay a fee to get trusted answers about your health.

Personalized answers

Other symptom checkers rely on static rules or protocols to give you their best guess at a diagnosis. K was built by doctors and trained on millions of real medical records to give you more accurate results.

Your records are always private

Records of your symptoms and care stay on your phone. Plus, K Health complies with both HIPAA + GDPR, the world’s leading standards for information security and privacy. We use anonymized data to make the app smarter, but we will never share your personal health information.
