Is your blood pressure too high?

Helfie’s Advanced Blood Pressure AI is designed to make regular blood pressure monitoring fast and accessible. It uses validated camera-based technology to estimate blood pressure and key vital signs, while your Health Intelligence (HI) helps you track results and trends over time.

Your Health Intelligence (HI) connects your checks, conversations, and uploaded health information to build a clearer picture over time.

Rather than looking at a single reading in isolation, it can help you track changes in your blood pressure and other vital signs, identify trends, and understand how factors such as sleep, exercise, stress, and lifestyle may be affecting your results.

Helfie’s Health Intelligence (HI) brings together information from your health checks, conversations, uploads, and history, then connects it with a vast body of medical knowledge to build an increasingly informed picture of your health.

Rather than relying on a single AI model or looking at each result in isolation, HI uses multiple layers of intelligence and machine learning to interpret health signals, connect related information across different areas of your health, and understand those results in the context of you.

It also maintains an active memory of your health journey, so previous results, patterns, and interactions can inform what comes next.

The result is intelligence that is personal, contextual, and designed to help you better understand and manage your health over time.

A health check gives your Health Intelligence new information about you. You can then talk to your HI about those results, ask what they mean, explore possible reasons for changes, and understand them in the context of previous checks and health history.

The conversation also becomes part of that context. So when you check again later, your HI can consider both your new results and what it’s learned from earlier checks and conversations.

This is how it builds a more detailed, connected picture of your health over time.

Helfie makes it easy to share check results and health trends with your doctor or healthcare provider, giving them a broader view than a single reading taken in a clinic.

This additional context can help with things like monitoring hypertension, reviewing medications, or understanding how lifestyle changes may be affecting your health.

Sharing your trends gives your healthcare provider more information to support better-informed decisions.

To improve the accuracy and relevance of your blood pressure results, Helfie uses a small number of personal details to tailor the calculation to you.

For blood pressure, this currently includes age, birth sex, height, and weight.
