How does it work?
Hilo is a subscription service that provides 24/7, cuffless blood pressure monitoring using a clinically validated, CE-marked Class IIa medical device.
1. Hilo Band
The Hilo Band uses optical sensors (PPG) to detect signals from your wrist. It calculates blood pressure using Pulse Wave Analysis (PWA) after calibration with the Hilo Cuff every 30 days. The band automatically measures your blood pressure around 25 times per day without any interaction.
2. Hilo App
The Hilo App syncs with your Hilo Band and displays how your blood pressure changes throughout the day and night, highlighting trends related to activity, meals, stress, sleep, and medication. You can share reports directly with your doctor or family.
How accurate is it?
The Hilo Band is a CE Marked Class IIa medical device that has undergone extensive clinical validation. Aktiia's technology is based on 20 years of research and over 100K users.
Two clinical trials have demonstrated accuracy comparable to a traditional upper-arm cuff, validated according to the ISO-81060-2 international standard.
What are the contraindications?
The Hilo Band is NOT INTENDED to be used on patients with sustained cardiac arrhythmias, conditions that reduce peripheral perfusion, pregnant women, damaged skin, or patients below 21 or above 85 years old.
