One membership, complete BP management.Can I buy the device without subscription?
No. Hilo subscription is required to use the Hilo Band. The technology depends on cloud-based algorithms and ongoing software updates that are integral to delivering medical-grade accuracy.
Your subscription includes the device, the app, continuous monitoring, and all features — making blood pressure management simple and affordable.
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.
The service includes two core components that work together to measure, track, and display your cardiovascular data:1. Hilo Band
The Hilo Band is a wearable device that uses optical sensors (photoplethysmography, or PPG) to detect signals from your wrist. It calculates your blood pressure using Pulse Wave Analysis (PWA) after a calibration with the Hilo Cuff, which is required once every 30 days.
The band automatically measures your blood pressure and heart rate around 25 times per day, without requiring any interaction.
It emits no lights or alerts, is comfortable, and is designed for continuous wear, including during sleep.2. Hilo App
The Hilo App syncs with your Hilo Band and gives you access to your health data. It displays how your blood pressure changes throughout the day and night, highlighting trends related to activity, meals, stress, sleep, and medication.
You can also share reports directly from the app with your doctor or family to your doctor about your results and never rely solely on this device for health decisions.
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.

Practical & Convenient
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 through out 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.
The bracelet paired with its blood pressure cuff has its own long lasting batteries easily chargeable & convenient to use, no long wires no big tunings, once charged can be used for a long time .
Aktiia app can be downloaded both for IOS or Android phones, which is easy to use & also keep records & generate records to show to your physician .
In current times I think its very important for everyone to keep a track of their health and aktiia app makes It easier to track, monitor and share the information with your healthcare provider easily.
The aktiia monitor has exceeded my expectations and I will definitely recommend it.

A comfortable gadget to wear throughout the day an
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.
