Your Health Story. All in One Place.
Connect Apple Health and supported wearables in just a few taps. Choose which health data to share, including medical records available through Apple Health. Or add your lab results, medical documents, insurance information, medications, allergies, and health history yourself. You're always in control of what you share. CLU brings it all together to understand your health in context.
Answers That Are Actually About You.
Ask anything about your health. CLU draws on your personal health history and scientific evidence to give you answers that fit your situation. It asks follow-up questions when needed, helps you make sense of your results and options, and guides you through healthcare and health insurance.
Looking Out for You, Even When You're Not Asking.
CLU brings together your health history, existing conditions, and continuously updated health data from devices connected through Apple Health. It uses that context to deliver relevant notifications, personalized information grounded in scientific evidence, and practical suggestions to support your health every day.
Make the Most of Every Doctor's Visit.
Tell CLU what you're seeing your doctor about. It'll guide you through a personalized checklist, organize your health history into a summary you can share with your doctor, and ask follow-up questions to fill in missing details. CLU also helps you keep track of what happens between visits, bringing together changes in your symptoms, medications, and health data over time — so you and your doctor have a more complete picture. Walk in better prepared and spend more time on what matters.
Your data stays yours.
Your health information is personal. We treat it that way. Your data is encrypted, never sold, and never used to train any AI model. We use it to make CLU work for you — not for advertising.
You're in control.
Choose what you share, manage your connected devices and data, and delete your information when you want.
Built with privacy in mind.
Your health records and conversations are protected by encryption and strict access controls.
Why we built CLU
Too often, healthcare gives us generic answers to deeply personal questions.
But the same symptom can mean very different things for different people. A lab result can fall within the normal range while showing a significant change from your personal baseline. And how someone responds to a medication can depend on their individual biology, medical history, and genetic background.
This matters especially in women's health, where research has historically overlooked important differences in how women experience health and disease.
We believe you can't understand someone's health through isolated data points or population averages alone. What matters is how everything connects.
That's why we're building CLU as one connected experience, where every part works together. Your lab results, medical history, wearable data, conversations, and new symptoms all contribute to an evolving picture of your health.
With that context, CLU can do more than provide personalized, evidence-based answers. It can help you make sense of meaningful changes, offer practical guidance tailored to you, and prepare for more productive conversations with your doctor.
Because we believe better health guidance doesn't come from adding more disconnected features. It comes from bringing everything together.
We're a small team with big ambitions and one simple but important goal: to make health guidance truly personal.
