Expect some problems getting started

The paper user guide, which comes in the package, is completely useless. There is no computer app linked to the band. There is no indication on the band which way it goes on the charger. So, it is a matter of luck whether you put it on the right way.

Dear Dom,

We are sorry to hear about your experience and truly understand how frustrating this must feel. We appreciate you taking the time to share this feedback.

We’re sorry that the paper user guide did not meet your expectations and that the setup experience felt unclear. Your comments regarding the lack of a computer app and the difficulty identifying the correct orientation of the band on the charger are completely understood. This is not the level of clarity we aim to provide, and feedback like yours is essential for us to improve both our documentation and overall user experience.

Our support team is always available to guide you through usage and setup step by step, and we genuinely encourage you to reach out so we can assist you directly and make things clearer.

Thank you again for sharing your thoughts — they have been noted and will help us improve.

Kind regards,
Your Hilo Team

Utter Rubbish and Zero Support

The device does not work, I tried to make contact with them to return it, but the instructions for returning it just keep looping back to the same start process. The device is so rubbish, I would advise anyone to keep their money and NOT raise their blood pressure trying to use this and get in contact with them, AVOID, AVOID and finally, Avoid!

Everything has worked really well so far

Took a few days to arrive, but arrived sustainably packaged, Royal Mail. I have an old Samsung phone- app and products installed seamlessly. Band needed charging, wish this was the same micro usb, but it's a quibble. Band fits my extremely small wrist with 3 holes remaining. Cuff fit my very large upper arm. Readings were roughly the same as nhs gp surgery reading. And since then, it's worked well. I wish the band was lavender, and a breathable sustainable material. But the device works well, my doctor likes it, it is never painful, i can see what impacts my blood pressure (caffeine!). I think some readings in the night are suspect because I'm lying on the band- but I deduce this from the other trend line data avaible in app.
I'm really not techie, gen x. This tech is super simple to use. Clean dashboard app. All data available. I really like knowing without a cuff compression. My Braun home cuff measurement was way off, this is quite accurate.
When I bought you're signed up to their club for a year for free.

I bought an Aktiia system in August 2024. It worked fine for a year and then stopped taking measurements, although it still talked to the phone programme. I have tried several times to contact Aktiia, now HiLo to arrange a replacement but hit a dead end on the website as the ChatBot (?) does not work and any contact with aktiia.com hits a dead name......
I have now managed to contact support-at-aktiia.com and it looks promising

The band stopped measuring blood pressure

I’ve been using the HILO band for almost 2 years. During that time it worked great: blood pressure measurements were stable, and the app and syncing had no issues.
However, recently the band stopped measuring blood pressure. Every time I try, it shows “band signal unstable” and no result appears.
Overall, it used to be an excellent product, but after two years this issue is very disappointing — it’s basically useless now. It’s especially frustrating because the device used to work perfectly.

Dear Seb,

We are sorry to hear about this issue and understand how disappointing it must be, especially after nearly two years of smooth and reliable use. It’s completely understandable to feel frustrated when a device that previously worked perfectly suddenly stops delivering results.

What you are describing is not the experience we aim to provide, and it is certainly not expected behaviour. Our support team would be glad to look into the “band signal unstable” message and help identify what is causing the measurements to stop.

We kindly invite you to contact us at support@aktiia.com
with a few details about your device, so we can open a support ticket and assist you as quickly as possible.

Kind regards,
your Hilo Team

Hilo is vastly superior to Hume Band

Hilo has a great product, far better than the Hume Band which does not meet product performance expectations at all

Dear Abyd,

We are sorry to hear about your experience and the frustration this has caused. We truly regret that the product did not meet your expectations and that you were dissatisfied with our service and delivery timeline.

We would like to clarify that we previously requested some additional information from you in order to open a support ticket and properly assist with your case. Unfortunately, we did not receive a reply, which prevented us from moving forward.

If your issue remains unresolved, we kindly invite you to contact us directly at support@aktiia.com
so our support team can review your situation and provide assistance as soon as possible.

unique monitor, good customer support

I have updated my score and changed my review. In my previous I said the tech was great but there was an issue pairing with a new phone. Although its is hard to get directly to real human past their AI bot customer care, I managed, and they solved my problem, which was a large part of my own making.....

Dear Will,

We’re really sorry for this experience, and you’re absolutely right — the article should be clearer and more complete. We’ll be reviewing and updating it so the instructions properly cover cases where a phone is lost or damaged.

Our support team has contacted you straight away and helped you get your band paired again. The issue was caused by the band still being linked to a different account than the one you were trying to pair it with, which prevented the connection.

Thank you for flagging this. Your feedback helps us improve both our documentation and the overall experience.

Warm regards,
Your Hilo Team

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.

Excellent customer care

I bought my aktiia cuff and wrist band 3 years ago. I used it happily for about a year. I then put it in the back of a drawer and deleted the app from my phone. I’ve tried to reactivate my use of it after a period of illness. My iPhone is still paired with both devices.

I can’t get onto the HiLo app. I get to pair devices on the screen and it comes back and tells me I’m already paired.

I got fantastic help from Klaudia HiLo .

Not so good in the customer care department.

I’d give it 0 stars if I could

I’d give it 0 stars if I could . My band only worked reliably for three weeks. Then it stopped giving any readings at all . It must be faulty . There is no address , email or phone number to contact them . It’s Lucy a chat bot. Which gives you a selection of answers . None of which applied to my situation. And nowhere to explain what my problem is or to let me speak to anyone . Luckily my husband paid by credit card,. So we will approach them . I have spent hours trying to find contact info . The email with the purchase is a no reply one . You only realise how good or bad customer service is when things go wrong . This has been a total nightmare. I had such high hopes for this band . But it’s been nothing short of a nightmare . Would not recommend this company .

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.
Also appreciated the free 12 month signup on the app.
I would recommend to anyone needing serious information about their blood pressure.

Well my unit worked well for the time I had it, but I lost the arm band out fishing and can't seem to source a replacement .
It looks like it would be less expensive to purchase a complete new set than just buy the arm band.
