Hilo Core

Your Hilo Core subscription gives you access to the complete Hilo Core System, including the Hilo Band, Hilo Cuff and the Hilo Core App. Together, these provide continuous blood pressure monitoring, insights and tools to help you understand your cardiovascular health.

With your subscription, you can:

• View your full blood pressure history: Access all your measurements and trends in the Hilo Core App.
• Track patterns and progress over time: See weekly and monthly averages, detailed timeline comparisons and insights into your blood pressure patterns.
• Monitor time in your target range: Understand how much time your blood pressure stays within a healthy range with Time in Target Range (TTR) insights.
• Generate doctor-ready reports: Create clear summaries of your blood pressure data to share during medical consultations.
• Add notes and track medication: Record health notes and keep track of medications or lifestyle changes that may affect your readings.
• Monitor sleep and activity: View sleep duration and daily step counts to understand how lifestyle factors relate to your blood pressure.
• Sync with other health apps: Automatically share data with Apple Health or Health Connect for broader health tracking.

Some features, such as phone-based measurements, are available only on compatible devices.

Hilo Core is designed as a complete blood pressure monitoring system, combining the Hilo Band, Hilo Cuff, and the Hilo Core App with secure data processing and ongoing software improvements.

To use the system, an active Hilo Core Subscription is required.

Unlike traditional blood pressure monitors that only provide individual readings, Hilo is designed to help you track your blood pressure continuously and understand long-term patterns in your cardiovascular health.

Your subscription supports the digital services that make this possible, including:

• Secure processing and storage of your health data
• Personalized insights and long-term trend analysis
• Advanced metrics such as Time in Target Range
• Doctor-ready health reports
• Integration with health platforms like Apple Health or Health Connect
• Continuous app improvements and new features

An active subscription is required to use your Hilo Band and access blood pressure data.
If you cancel:

• You will have 30 days of limited access (last 24 hours of data only).
• After 30 days, new blood pressure measurements and insights will no longer be available.
• Your Hilo Band remains yours to keep.
• Your historical data remains securely stored.
• You can keep the cuff and continue to use it for one-off readings.
• You can reactivate your membership at any time to resume continuous monitoring and regain full access.

Hilo Core is a subscription-based wellness system designed to help you understand how your daily habits relate to your blood pressure patterns over time.

The Hilo Core experience combines three connected components:



1. Hilo Band (wellness layer)



The Hilo Band is a wearable device that uses optical sensors on your wrist to collect physiological signals while you are still and at rest.
These signals help build insight into longer-term blood pressure patterns and trends over time rather than isolated point-in-time measurements.
The band is designed for everyday wear, including during sleep, and continuously collects data in the background to help you better understand how your routines, sleep, and daily habits relate to your patterns over time.



2. Hilo Cuff (reference measurement layer)



The Hilo Cuff is an FDA-cleared blood pressure monitor that provides exact reference blood pressure measurements using an upper-arm cuff.
The cuff is used:

• During the calibration process
• Every 30 days to maintain an accurate baseline for the Hilo Band
• Anytime you want an on-the-spot, exact blood pressure measurement

Cuff measurements can also be saved, reviewed, and shared with your doctor through the Hilo App.



3. Hilo Core App



The Hilo Core App brings your information together in one place and helps you:


• Observe longer-term trends and patterns
• See how your patterns relate to sleep, activity, and daily routines
• View summaries and averages over time
• Access exact cuff measurements separately from band trend information
• Generate reports to download or share

Understanding the difference



The Hilo Band and Hilo Cuff work together, but they serve different purposes:


• The Hilo Band helps you understand longer-term patterns and changes over time
• The Hilo Cuff provides exact reference blood pressure measurements
• The app displays both clearly, while keeping wellness trends and cuff measurements separate.

Hilo Core is designed for adults who want to better understand how their daily habits relate to their blood pressure patterns over time.
It is intended for general wellness use and for people interested in tracking trends and building awareness of their data.


⚠️ Who should not use Hilo Core?


Hilo Core may not be suitable for everyone.
You should not use the Hilo Band or Cuff if:

• You are pregnant or may be pregnant
• You have damaged, irritated, or injured skin where the device would be worn
• You have an implanted electronic device (such as a pacemaker or defibrillator)
• You have a condition that may affect how signals are detected at the wrist or arm

If you are unsure whether Hilo Core is appropriate for you, consult a healthcare professional.


ℹ️ Important information

• Hilo Core is designed for wellness and awareness, not medical use
• It does not provide diagnosis, treatment, or clinical monitoring
• The cuff provides reference measurements, while the band supports trend awareness over time

Hilo Core combines reference measurements with ongoing trend insights:

• A cuff-based monitor is used to take point-in-time reference measurements of your blood pressure.
• The Hilo Band collects optical data from your wrist and uses it to provide context and visibility into how your blood pressure patterns evolve over time.

To ensure reliable insights, the system:

• Takes readings when you are still and at rest
• Uses periodic cuff measurements to anchor and calibrate the system

Rather than focusing on individual readings, Hilo Core is designed to help you:

• Observe long-term trends
• Understand how patterns change over time
• Build awareness of how lifestyle factors may relate to those patterns

While exercising, the Hilo Band will continue to count your steps, helping you understand how exercise influences your daily blood pressure trends.

To ensure consistent blood pressure and heart rate measurements, the Hilo Band uses an accelerometer to gauge movement and will only attempt to take readings when you are still.
