What is Aktiia?
Hilo (formerly Aktiia) is a medical-grade wearable blood pressure monitor that tracks your blood pressure automatically 24/7 without any manual measurements or annoying cuffs. The Hilo Band uses optical PPG sensors and clinically validated proprietary algorithms to take approximately 25-50 measurements throughout the day and night, identifying your blood pressure patterns and trends including during sleep. This eliminates the blind spots of traditional cuff-based monitoring and provides a complete picture of your cardiovascular health.
Key features include the Hilo App which displays real-time insights and personalized recommendations showing how stress, meals, medications, activity, and sleep impact your blood pressure. The device is 100% waterproof (IP68 certified), has a 15-day battery life, and syncs measurements via Bluetooth. Users can share personalized insights directly with doctors or loved ones from the app to create action plans. The system has been validated through 6 major clinical trials and holds FDA 510(k) clearance for over-the-counter use as the first cuffless blood pressure monitor.
Hilo is designed for people with hypertension or those at risk, their doctors and caregivers, and anyone wanting proactive blood pressure management. It's ideal for users tired of manual cuff measurements, those who need to monitor blood pressure during sleep, and people who want to understand lifestyle factors affecting their blood pressure. The device is trusted by doctors, certified as a Class IIa medical device in Europe, and has collected over 12 billion data points from 130,000+ users across Europe.

Frequently asked questions about Aktiia
What is Hilo (Aktiia) and how does it work?
Hilo is a medical-grade wearable blood pressure monitor that tracks your blood pressure automatically 24/7. The Hilo Band uses PPG (photoplethysmography) optical sensors on your wrist to acquire data, which is transferred via the Hilo App to a secure cloud server. Aktiia's proprietary algorithms process the optical data to estimate blood pressure. The device detects if you're moving and only measures when you're still. It takes approximately 25-50 measurements around the clock, including during sleep, providing comprehensive patterns and trends rather than isolated snapshots.
Is Hilo clinically validated and medically approved?
Yes. Hilo has been validated through 6 major clinical trials, the healthcare industry's gold standard. It received FDA 510(k) clearance as the first over-the-counter cuffless blood pressure monitor. In Europe, it has CE Mark approval as a Class IIa medical device, signifying it meets high safety, health, and environmental protection requirements. The technology is backed by 20+ years of research, 35 collective patents, and data from over 130,000 users across Europe.
What's included when I purchase Hilo?
When purchasing through the website, you receive: the Hilo Band device, everything needed to get started (accessories), standard shipping within 10-14 days, applicable taxes (all covered in listed price), 1-year membership with full access to all benefits (365 days), and the Hilo App which is free to download on iOS and Android. The 30-day trial membership mentioned in older information has been updated to 1-year included with purchase.
How much does Hilo Membership cost after the trial?
New Hilo customers receive a complimentary 14-day trial of Hilo Membership. After the trial period, standard membership pricing applies: £4.99 per month for monthly plans, with annual plans also available. Membership must be activated directly through the Hilo App (cannot be added during device checkout). Membership is linked to your Hilo App account, not the physical band, so purchasing additional bands with an existing account does not include free membership.
Is the Hilo Band waterproof and how long does the battery last?
Yes, the Hilo Band is 100% waterproof with IP68 certification, meaning you can wash, swim, and shower with it on - it's safe and keeps working. The battery lasts up to 15 days on a single charge, so you only need to charge it about twice per month. This long battery life and waterproof design enable true 24/7 continuous monitoring without interruptions.
Who is Hilo suitable for?
Hilo is approved for ongoing monitoring of adult patients at home with hypertension or those at risk. It's designed for people who want proactive blood pressure management, their doctors and caregivers who need to understand blood pressure patterns, and anyone tired of manual cuff measurements. The device is for monitoring purposes (not diagnostic) and is suitable for users who want to understand how lifestyle factors affect their blood pressure and make informed health decisions.
What accuracy does Hilo have compared to cuff measurements?
Hilo has BP cuff-equivalent accuracy as evidenced by 6 clinical trials. The device was trained on 12+ billion data points from 130,000+ users to develop accurate pulse wave analysis algorithms. In clinical studies, Hilo yielded equivalent daytime blood pressure measurements compared to 24-hour ambulatory blood pressure monitors. The integrated oscillometric cuff handles calibration silently in the background for consistent accuracy without user intervention.
