Brand History

Brand History

Hilo is the consumer brand of Aktiia, a Swiss-based health technology company founded in 2018. The brand is built on over 20 years of research and a mission to eliminate the "silent killer" of hypertension through proactive, data-driven monitoring. Hilo distinguishes itself by bridging the gap between high-end medical devices and consumer wearables. It holds a Class IIa CE-marked medical device certification, indicating it meets rigorous European safety and performance standards. The brand’s identity is centered on "Blood Pressure Intelligence," moving away from static measurements toward a holistic understanding of how lifestyle factors like sleep, stress, and activity impact heart health.

Brand Overview

Hilo is a health technology brand that provides a wearable system for continuous blood pressure monitoring. It offers a combination of a smart wristband and a mobile application that work together to track, analyze, and present blood pressure data in real time. The brand’s core offering includes automatic measurements throughout the day, personalized health insights, and tools to share reports with healthcare professionals. By replacing traditional cuff-based monitoring with a more convenient, always-on solution, Hilo aims to help users take control of their heart health and make informed lifestyle decisions.

The main product featured is the Hilo Band, a lightweight, wrist-worn medical device designed to continuously monitor blood pressure. Unlike traditional monitors, it uses optical sensors and pulse-wave analysis to measure blood pressure without requiring repeated manual input. The device works alongside the Hilo app, which displays trends, daily averages, and health insights.

It is a clinically validated, CE-marked medical device, capable of taking multiple readings daily (around 25+ times) and generating hundreds of measurements per month. Additional features include long battery life, water resistance, and the ability to share reports with doctors.

Customer Reviews

Practical & Convenient (Sourced by: Hilo)

The Aktiia 24/7 blood pressure monitor is the most practical and great addition to my gadgets. Its Aktiia app is very user-friendly and easier to set up. Once connected, it takes your average blood pressure reading by taking 3 readings. Then it takes 1 reading every hour throughout the day, giving you a better insight by giving you the average blood pressure as well as your heart rate. The blood pressure monitor bracelet is comfortable to wear and use throughout the day.

This bracelet is a great way to monitor blood pressure. It also has a very sleek and stylish design, which I love. I never realized how much my blood pressure varied at different times of day and night. The app for the monitor is an excellent companion for it – it is very easy to use, understand, and follow. The app also makes it effortless and convenient for me to share my information as and when required. The measurements taken from this device are accurate, and I have really benefited from monitoring my blood pressure on a regular basis. This bracelet is a real game-changer, and I highly recommend it to anyone needing to monitor blood pressure regularly.

Understanding Hilo’s Position in the Digital Health & Wearable MedTech Industry

Hilo represents a fundamental shift in the MedTech industry, moving away from the "one-and-done" hardware sales model toward a Software-as-a-Medical-Service (SaaMS) approach. In this model, the physical wristband is merely the gateway to a continuous health intelligence platform. By utilizing a subscription structure, Hilo ensures that users aren't just buying a sensor but are investing in an ongoing service that includes regular algorithmic updates, secure data hosting, and the automated generation of clinical reports. This alignment ensures the device remains medically relevant over time, as the software continuously refines its accuracy and provides deeper analytical insights into the user’s cardiovascular trends that a standalone device simply could not offer.

Furthermore, this SaaMS model positions Hilo perfectly within the rapidly expanding Remote Patient Monitoring (RPM) sector. By providing a constant stream of high-fidelity data, the brand moves healthcare out of the doctor's office and into the patient's daily life, aiming to reduce long-term costs associated with hospitalizations and undetected heart events. For the user, the subscription covers the "total cost of care," including the essential calibration cuff and a seamless replacement cycle for hardware. For the broader healthcare industry, Hilo’s model serves as a blueprint for how digital health brands can maintain a persistent, life-saving connection with patients through a sustainable, service-oriented business strategy.

Hilo Band: BP Monitor Bracelet

BP Monitor Bracelet

The Hilo bracelet operates using proprietary Optical Blood Pressure Monitoring (OBPM) technology, which eliminates the need for a traditional inflatable cuff. At its core, the device utilizes photoplethysmography (PPG), the same green-light sensor technology found in standard fitness trackers, to detect changes in blood volume within the vessels of the wrist. However, while most wearables only measure heart rate, Hilo’s advanced sensors perform pulse wave analysis (PWA). By analyzing the specific shape and speed of the pulse wave as it travels through the arteries, the device's algorithms can calculate systolic and diastolic blood pressure levels with clinical precision.

To ensure these optical readings remain accurate over time, the system follows a hybrid process that includes automatic background measurements and a monthly calibration. The bracelet uses an internal accelerometer to identify moments of physical stillness, such as during sleep or while sitting, to trigger readings automatically, capturing roughly 25 data points every 24 hours. To "ground" these optical signals in clinical reality, users perform a once-a-month calibration using a traditional upper-arm cuff provided by Hilo. This manual reference point allows the software to adjust for the user's unique arterial stiffness and physiology, ensuring that the passive, 24/7 monitoring remains as reliable as a medical-grade diagnostic tool.

Hilo App

Hilo App

The Hilo app functions as a sophisticated bridge between the raw data captured by the wristband and the actionable insights needed for cardiovascular management. By synchronizing via Bluetooth, the app automatically plots approximately 25 daily readings onto a continuous timeline, allowing users to visualize how their blood pressure fluctuates in response to daily triggers like stress, caffeine, or exercise. Beyond mere visualization, the app serves a critical clinical purpose by generating comprehensive "Digital Health Reports." These PDF summaries compile 30 days of continuous data into a format specifically designed for doctors, providing a more accurate "ambulatory" view of a patient’s health than a single, high-stress measurement taken during a traditional clinic visit.

To maintain clinical-grade precision, the app orchestrates a hybrid "calibration" process, prompting users once a month to verify their wristband's data against a traditional upper-arm cuff. This ensures the optical algorithms remain perfectly tuned to the user’s unique physiology. Furthermore, the app acts as a proactive health coach by integrating lifestyle metrics, such as sleep quality and step counts, to help users identify correlations between their habits and their heart health. Through automated notifications, medication reminders, and alerts for significant baseline deviations, the app transforms passive monitoring into an active, data-driven engagement strategy that keeps users informed and prepared for medical consultations.
