Hilo by Aktiia Reviews 5,645

Accuracy is very questionable. The key seems to be the calibration. However, the variance in readings especially overnight caused huge anxiety. In the end I have stopped using Hilo and had a professional 24hr BP undertaken at cost. This removed the anxiety and made me realise the traditional BP is best. I think with more research and product testing it could be good. However, from my perspective it is far from reliable and not there yet.

Here’s a polished version you can use for feedback about Klaudia:

**Klaudia provided excellent support throughout my query. She was proactive, resolved the issue quickly, and communicated in a kind and professional manner. She was easily accessible and demonstrated strong knowledge in addressing my concerns.**

I ordered the product in October 25. It worked for one month then started to fail. I notified the company and was offered remedial actions. The device initially worked then failed again. At the same time I developed a severe rash under the wrist band.
I contacted Hilo, showing full details and photos. On the 2nd of February 26 they the emailed me a confirmation of a refund on return of the product.
I returned the product as asked, with proof of postage on the 4th of February. The return label was to a UK based address. I was told in the refund email, that my refund would happen within 30 days of receipt of the product.
I have contacted the company by email on several occasions but just get a standard response with no reply facility.
I would like my £188.99 refund as promised.

Calibration worked like a charm and the measurements showed right after completion. The various measurements during daily activities including the sleep cycle are now known to me instead of guessing. Medication changes might give new insights soon too.

I like the Hilo band but unfortunately it has stopped working, I am unable to charge it. This has now been the case for a month. I am getting continued requests for further information and photographs. I have sent a video demonstrating that the band is not working and numerous photographs but they continue to require further information so they can “assist me further”. I am not sure what Aktiia customer support think they can do. I am going to see if I can get a refund from Amazon and move on to another brand hopefully with a better outcome. Product good, customer support poor!

Update
Ok, since my latest communication Aktiia ( Hilo) have come back and given me a free replacement, so all good in the end but why oh why was this only done under threat of a negative review. So good outcome but disappointing journey.

The device unfortunately doesn't offer accuracy in readings compared to conventional blood pressure devices. Customer service and return policies options seem to be hidden

First, having a wearable device for blood pressure is very important as such. Second, the app is well Made and helpful. Two issues beyond the General question of reliability of measurement: the strap seems of a material that promotes fungal infections, not only once. Second, It would be Most appreciated to have the Option to measure on demand with the strap. perfect Customer Service.

Easy ordering, fast delivery and easy set up and calibration. Does what it says in the promotion words.

1. Delivery was fast.
2. The quality is top grade.
3. Setting up is straightforward and the app is user friendly.
4. All the readings taken correspond with my manual sphygnamometer.
5. Backup from Aktiia support is first class.
I have found this instrument surpasses any expectations I had and the information I get from it justifies the expense and, more importantly, very useful.

I have had Hilo for over 6 months.
Ok product but terrible customer service. Impossible to get hold of anyone in real time. Slow response (24-48hrs +) to chat bot. Frustratingly limited range if FAQs which is all you have in real time.
For a ‘clinically validated’ blood pressure monitor the lack of support is damning. It is certainly not worthy of being considered a medical grade device.
Feels like they have pared back any customer support staff to the bone.
The product itself is unreliable:
1) It doesn’t seem to be able to pick up signals a lot of the time with the consequence that the ‘24hr’ monitoring advantage isn’t quite what it seems.
2) I have also had to re-pair the band to the app several times as it simply stopped collecting data.
3) The process of recalibration with the arm cuff (required every 30 days or so) is unwieldy, and despite following instructions to the letter it never works first time.

Feels like a beta product that has been rushed onto the market too soon at the behest of investors.

[note: Aktiio seems very quick to respond to negative reviews and phoned me very shortly after I posted my review , but I was not able to answer at the time and they left no number to call back on and did not (contrary to message below) send a follow-up email.
This isn’t proper customer service - it should be possible to get hold of customer support staff without all this hassle]

My query was registered via the AI chat bot on Sunday. I received an informative email on Tuesday enabling me to request a replacement. Very seamless service

SCAM ALERT! Join the Facebook group "Hilo/Aktiia Horror Stories". Bought Jan 14, received a damaged scuffed up cuff that was giving exactly 20-24mm higher systolic than reality. I was told to return it and they would send me a promo code to order a new cuff. 6 weeks later,I have received nothing. They have ignored all messages and follow-ups and they have no phone number or live chat. At this point I will have to dispute the charge on my credit card. I spent $320 and have no working product and the merchant is unresponsive. DO NOT BUY!!!!!

This merchant has a long track record of ghosting customers.

Prompt delivery.
I had some difficulty setting the device up, initially I could not get a reading from the wrist band despite many attempts. I shaved my wrists but changing from my non-dominant to dominant wrist resolve the issue.
I think that initiallyI had the wrist band too tight made more difficult by the small size of the band delivered with the device.
It now works really well giving readings throughout the day and night.

I started using Hilo because I wanted more peace of mind and a clearer picture of what my blood pressure is doing across a normal day and night. The difference compared with occasional cuff checks is huge. Hilo quietly captures readings throughout the day, and when you open the app you can actually see patterns, trends, and how things change over time. It feels practical and empowering rather than medical and intimidating.

Hilo is a genuinely reassuring way to understand your blood pressure. What I appreciate most is how thoughtfully the features are put together. The band is light and comfortable, the battery lasts ages, and it is water resistant, so you do not have to baby it. Once it is set up, it just becomes part of your routine and the information builds in the background. In the app, the insights are clear and genuinely useful, especially the ability to view your day and night averages, see time in target range, and generate reports you can share with a GP or consultant.

I also like that it brings blood pressure together with sleep and movement, because it helps you spot connections and understand what might be influencing your readings.

I also want to mention Klaudia, who was outstanding. Klaudia was patient, thorough, and genuinely focused on helping, not rushing, genuinely keen to ensure a happy customer. Support like that really matters with a health product, and Hilo are very lucky to have someone like Klaudia representing them. Overall, I would absolutely recommend Hilo if you want a reliable, everyday view of your blood pressure and a much better sense of what is going on.

I bought the Hilo Band because I wanted a medically credible way to understand my blood pressure in real life, not just a one-off cuff reading. It has delivered exactly that: automatic, round-the-clock tracking (about 25 readings a day, over 800 measurements a month) with clear trends and insights that actually help you understand what is going on. 

What I like most is the way Hilo turns the data into practical metrics and patterns, including day vs night averages and “time in target range” (TTR), plus reporting that makes it easier to have a meaningful conversation with your GP or consultant. The app also links trends to lifestyle factors like meals, stress, sleep and medication, and makes it straightforward to share reports.

Features and design highlights that I liked (as a day to day user):
- Clinically validated, CE-marked Class IIa medical device, built around a wearable band plus an initial calibration cuff.
- Optical sensing (PPG) with pulse wave analysis, then hands-off monitoring day and night.
- Sleep and movement tracking now integrated alongside continuous blood pressure insights. ()
- Battery life is excellent (up to 15 days), and it is water resistant, lightweight (16g), and simple to live with. 
- Strong technical credentials (meets ISO 81060-2; stated mean error within ±5 mmHg for systolic and diastolic).
- Very comfortable to wear and you forget it is on your wrist after a day or so

Finally, a special mention for Klaudia in customer support -  Klaudia was extremely helpful, diligent, and genuinely customer focused in helping me on a few things/questions. The organisation is very fortunate to have staff like Klaudia interfacing with and helping customers. For sure, Klaudia made a real and significant difference to my experience and confidence in the product. Cudos to Klaudia and the support team!!

I purchased hilo via their web site and am yet to receive a confirmation email on payment confirmation and expected shipping time.

I note that there is no Support Email or Contact Details. Ordinary experience given the premium cost of the product on offer?

I was one of the first users having been given the Band to me by a friend. The first one lasted rougly 3 years and only failed because I took it into the shower as it was not yet waterproof. Acquired a new one and I am more than happy with it. New features have been added at no extra costs. Can only recommended it.

Can’t fault the service from Hilo. Band is on and working well. Still calibrating my BP over the first 4 days. Delivery in the UK was an issue. Royal Mail said they attempted to deliver three times but I waited at home for 3 days and there was no attempt to deliver. I had to go and pick it up myself from the sorting office 😠😠☹️☹️

I'm frustrated by the 4 day calibration. Less in doing it but mire there was no clear communication to expect this. Also no clarity around if I need to do this at the same time of day, different times of the day or if it doesn't matter when I do it. Subsequently I feel I'm guessing which is the opposite of the point in getting this thing. I hope I'm happier once day 4 is over.

I got hilo since June 2025 and I’m amazed by the readings. It gives you important trend changes and you can share it with your doctor. HOWEVER…. since October it got difficult to charge the band and I think it’s a construction or design fail. I have to press it or put the Hilo band/charger under a 3 kg weight so it can make contact (I’ve cleaned it several times since that could be the problem). Besides : if the charge would last almost one month at the start, it now is just 10 days. I’ve tried to give feedback through their annoying chat bot and sending a picture of the band. NEVER received reply. CUSTOMER SERVICE 0%. U should be ashamed because your product has such a potential. Let’s see if I find a reason to change the rating of this review
