Frequently asked questions
How does it work?
Hilo is a clinically validated, CE-marked Class IIa medical device for monitoring blood pressure in adults for everyday personal use. It includes two core components that work together:
Hilo Band
The Hilo Band is a wearable that uses optical sensors (photoplethysmography, or PPG) to detect signals from your wrist. It calculates your blood pressure using Pulse Wave Analysis (PWA), following a calibration with Hilo Cuff.
It tracks your blood pressure and heart rate automatically—about 25 times per day—without requiring any action from you. There are no lights or alerts, and it’s designed to be worn continuously, even while sleeping.
Hilo App
The Hilo App syncs with your Hilo Band and gives you access to your data. It shows how your blood pressure changes throughout the day and night, with trends linked to your activity, meals, stress, sleep, and medication. You can also share reports directly from the app with your doctor or family.
How accurate is it?
The Hilo Band is not a simple consumer wearable device. The Hilo Band is a CE Marked Class IIa medical device that has undergone extensive and thorough clinical validation.
Aktiia’s technology powers Hilo and is based on 20 years of research and over 100K users.
While developing the technology used in the Hilo Band, two clinical trials have been conducted that have demonstrated that its accuracy is comparable to that of a regular cuff that you would place on your upper arm. In particular, our medical device has been validated in patients representing the general population, according to the ISO-81060-2 international standard.
What are the contraindications?
Please refer to the user manuals to check the contraindications and specifications:

This bracelet is great way to monitor blood pressure – it also has a very sleek and stylish design which I love. I never realised 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.

Aktiia 2.0
Hilo Band is the best monitoring system that a patient of cardiovascular accident like me (aortic dissection) can dream to have today. Still it could evolve and improve to help further the users as one return to a more active life after some months of recovery. Here is how I imagine Aktiia 2.0: the software and app would evolve to a 3 modes activity and measurement: Normal (as of today, with a measurement made every 2 hours), Sport (with a measurement made every 10 minutes), Immediate (with a one-off measurement to check blood pressure in case of stress). This would be a fantastic evolution for the patients. And an innovator needs to be ahead of its competition.

Great Product
I found the monitor simple to set up as a result of the clear instructions that come with it. The monitor itself is quite small and i found that I forgot it was there after a short while.
I have been able to obtain very regular blood pressure reading throughout the day and night and my GP was able to confidently adjust my mediation based on the readings and the report.
I would suggest that the monitor is offered with different sized wrist bands. The original that come with mine was a little short. However, one email to the support line resulted in a larger one being sent free of charge.
Overall I’m really pleased with my purchase which has delivered on expectations.
Britta
Gamechanger device
I needed to monitor more closely my blood pressure since I knew y blood pressure was /is borderline if not high but even looking at a standard cuff makes me uneasy, so was willing to give Aktiia a go and I was super apprehensive about it but I just couldn’t stand checking my blood pressure with a standard cuff anymore, so wanted to give it a go. I have been using it now for roughly 2 month and I couldn’t be happier with my purchase, this bracelet is a utter gamechanger, I know now whats going on and what I need to fix, so with that I has no problems recommending it to a friend who already reports similar to me

Superb!
So I’ve been using this now for a short while and everyday I’m learning more about it as I play about with it. The bracelet is comfortable and lightweight, and smartphone app delivers blood pressure information quickly and efficiently. The app is of course easy to install and available on apple and android store for download.
The bracelet/watch as I call it is very comfortable and makes it easy to keep check on my blood pressure at any given time. And also allows me to monitor it over a period of time which is useful. During a time where we’re struggling to see a GP face to face in the UK I’ve found this invaluable saving worry and having to try get am appointment with my GP.

I am using this device for almost a week. Very happy with the results. It shows your blood pressure every 2hours in an apps that is sync with the wrist band. It also have a separate arm blood pressure device, that I used to get the accurate blood pressure. The wrist band after wearing it, it connects to your phone, where it records every blood pressure and measures it. Both the devices are connected and operated through apps.

Simple, accurate and comfortable to wear.
Having had a 24-hour blood pressure monitor from a hospital, which woke me every 15 minutes through the night to take readings, Hilo Band is a dream. The wrist band is so light and soft, I forget it’s there and sleep is no problem.
It is clear and easy to set up and works well. I could compare it to the results of my conventional blood pressure monitor and Aktiia gave identical results.
It does tend to miss a couple of readings in every 24 hours, but it still has more than enough information and both blood pressure and pulse. My doctor is going to be very impressed when I present a printout of my results.

The Best on the Market
This is by far the best Blood Pressure monitoring system on the market nothing comes close. I have used various gadgets and monitors in the past but most just didn’t give me very accurate results so I needed something more and I’m really glad I’ve found this Aktiia monitor it’s just fantastic just out it in your wrist and it will continuously monitor your bloody pressure. I would highly recommend this.

Very useful
Have been using the product for a while now to keep an eye on blood pressure. There are 3 elements to this.
1- the wearable wrist strap, like a watch / Fitbit, unobtrusive and comfortable.
2- the inflatable cuff, only use occasionally, however could use more frequently if you wanted
3- the app which allows you to see all data.
The wrist strap providing info to the app every hour including while you sleep.
Have found the product to be useful, you can download a pdf of the readings to provide to doctors if needed or just to see for yourself.
Interesting to see how much it varies throughout the day and especially during the night, the. Igbo being a good measure as can flag issues otherwise not picked up
