Reviews
The only wearable that actually solves a real problem
This is one of those rare, genuinely life-changing devices that solves a real problem in a market flooded with mediocre and largely pointless wearables. Most wearables feel like solutions looking for a problem. Hilo is the opposite. Hypertension is a silent killer. It is far more common than most people realise and it progresses quietly over months and years. Taking a single blood pressure reading once a month is meaningless. It is like looking out of the window on a cold January morning and concluding that summer will be dry and sunny.
No one has the time or patience to measure their blood pressure manually dozens of times a day, every day of the year. Hilo does exactly that. It captures thousands of data points and reveals how blood pressure is really behaving beneath the surface, including patterns that would otherwise go completely unnoticed.
In my case, it showed consistent blood pressure peaks between 2:00 and 6:00 am. That insight alone was invaluable. I was able to take a clear, data-backed report to my GP, who was so impressed that he decided to buy one himself.
If you are over 50 and care about your heart and kidneys, this device is a no-brainer. Hilo has clearly invested heavily in research and clinical validation. The science is solid, credible, and robust enough for publication in top-tier scientific journals. They have gone through every regulatory and technical process required, including FDA approval, which gives real confidence in the data.
At around £200, this is without question the best money I have ever spent on my health. The software has a few minor teething issues, but that is a trade-off I am happy with. Hilo focused on making the measurements accurate and trustworthy, not on making the data look pretty. The foundations are rock solid. The polish will come.
Hilo/Aktiia BP/HR monitor is truly amazing.
Firstly; The Hilo device is extremely comfortable to wear and is amazing at providing a reassuring constant 24/7 monitoring on my BP&HR. It is extremely interesting monitoring my stats during rest versus activity. All statistical results can be printed or sent via email to my Doctor if required. Providing me with comfort to know that my stats are well within range.
Add to this a customer services that are truly amazing, by providing speedy responses and swift actions to the customers during times of need. Personally, I am one very satisfied customer.
A good experience all round.
Have been wearing mine for a week now and for the first time I feel I am getting real useful information. The readings are accurate and the system was pretty easy to set up - just follow the instructions. Ordering and delivery were both straight forward and stress free.
Looking forward to gaining further insight as I go along. I would recommend to anyone needing serious information about their blood pressure.
I was looking specifically for a watch…
I was looking specifically for a watch which would keep a constant check on my blood pressure and pulse, with clinically backed technology. I could find lots of watches that measure pulse but not trustable BP. I've had my HiLo for less than a week but the readings and displays are so informative and means I can visit my GP for a High Blood Pressure review with the data that is easy to understand.
Reliable Results and Outstanding Support
I’m really impressed with this blood pressure monitor and the company’s overall service. The device is reliable, straightforward to operate, and provides consistent readings that help me stay on top of my health. Customer support was quick and helpful when I had a question. Excellent products that truly make a difference - would highly recommend
