Did you by chance get the app to work on an iPhone?

Thx!

Aktiia is good but not great. Several papers (by independent researchers and by the Aktiia team) showed that the nighttime values were incorrect. However the daily and 24h averages are okay if you average over a week.

Two family members use it and are happy with it.

It’s helpful when you introduce a new antihypertensive. It might also be good to check once in a while. But if you only want to check once in a while (let’s say once a year) then buying an FDA approved 24h ABPM is the gold standard, as suggested by @DrFraser.

Conclusion: if you can access it (Europe or Canada), if you have the money and if you have elevated BP then go for it. If not: better to wait or better devices.

No, I have an Android device. It may trickier on Apple.

It sounds as though this is a good device for averages. However, for individuals who have hypertension, as the nighttime pattern is very important to assessing risk from the hypertension, I’d still want a standard 24 hr ambulatory. I just purchased one with all 3 cuff sizes and software, with tax/delivered $190. Went with the Contec ABPM50. I think all my patients with hypertension should have one an periodically monitor to make sure their is good control and also stategize in taking meds - for example, if no overnight dip, take all meds at bedtime and retest.

I have put the iPhone question out to someone who can advise, and if it’s possible, I’ll order an Aktiia for my husband and I to share (I have good bp, so aside from a random spot check, I’m probably fine to mostly do without).

I imagine the Contec for humans is good, and you might already have experience with them, but I’ll just share bought their pet version and the readings were very dissimilar to the $$$ monitor I borrowed from my vet. The price point was much lower than the one you purchased which might explain the quality difference. And of course, I possibly received a dud.

Hi Beth

Yes I have started to use it over the last week. For me I would say

Pros: Fits really well, small size and battery still OK after a week.
The app logs BP every 2 hours by taking a number of readings and then averaging. Mine takes between 1-3 and occasionally misses, reading the notes this is most likely due to me moving too much or exercise etc. You then get a daily, weekly and monthly average. So lots of averages !

Cons: The app is slightly flaky on android, some text gets overwritten and I have had to force stop a couple of times when it created pop ups that could not be closed
It’s supplied with a cuff to calibrate the device on a monthly basis. I initially did this when I was a bit cold and I think it had a negative impact on the results as they seemed a bit high. I did another calibration and the results are getting closer to my results on my Omron cuff.
Not sure about accuracy mine seems to be reading high but would want to see over a month. I would tend to agree with the other posters

The initial thread was about Rapamycin increasing BP. When looking at my manual Omron Cuff readings it does look like my BP has increased after taking 6mg with olive oil every week
Average before: 124/79 pulse 60 (min 98/58 54) (max 146/90 62) n=66
Average after: 130/82 pulse 61(min 111/68 56) (max 156/111 79) n=62
This is why I bought the Attia. I have now stopped the rapamycin to see if I can get a baseline I can trust.
Hope this helps

My friend got back to me. He said the tricky part is getting the financial information from a friend in the UK or Canada.

Once you do that, there is a good chance we can get the app on the iphone, but because it might not work, he suggested we do this step before making the purchase.

I know these people well enough to ask them to mail something for me, but I am not sure about asking for the credit card info. I’ll give this thought.

You basically sign out of your device and restart an apple account as if you live somewhere else. That is when you need to input your credit card info and address (incase you buy things apple offers). Maybe there is a way to bypass this step

I’ve also messaged the company to ask if they expect it to arrive in the US in the first or second half of 2025.

This video lays it out clearly.

Sure, I recommend Aktiia, but with one objection, I don’t think it makes any more sense for healthy individuals with normal BP beyond what PA suggests as a twice yearly measuring protocol, when you measure your BP for a week or two 4 times daily. For me Aktiia was pretty accurate, but my BP is really stable at around the 110/65 and slight variations of ±5 point don’t make sense of me wearing a continuous BP device. I wish it would be integrated in apple watch, that would make more sense than wearing specific BP device. Mine was not waterproof and strap looks really cheap silicone and I stopped wearing it after 6 months.
If you have problems with your BP, have BP medication and want to see how it is working, what makes your BP jump or sink, this is a great device. But for me personally it doesn’t make sense. I will continue to use it twice yearly for a month to see if my BO is still in check.

Evaluation of Aktiia cuffless blood pressure monitor across 24-h, daytime, and night-time measurements versus ambulatory monitoring: a prospective, single-centre observational study 2025

No significant differences emerged between the Aktiia and ABPM monitors for 24-h and daytime SBP (24-h: μ±σ[95%CI] 2.6 ± 12.3 [-0.2, 5.4] mmHg, r = 0.57, P = 0.06; daytime: 1.2 ± 12.4 [−1.6, 4.0] mmHg, r = 0.60, P = 0.38). Night-time SBP showed more evident differences (12.5 ± 14.4 [9.3, 15.8] mmHg, r = 0.39, P < 0.001). DBP were within clinical range across 24-h and daytime (24-h: −2.9 ± 7.9 [−4.7, −1.1] mmHg, r = 0.63, P = 0.002; daytime: −3.1 ± 8.2 [−5.0, −1.3] mmHg, r = 0.64, P = 0.001), and showed significant differences for night-time (4.1 ± 8.5 [2.2, 6.0] mmHg, r = 0.57, P < 0.001). The concordance rate with ABPM’s nocturnal dip was 79% for 1-day average from Aktiia.

This is done by the Aktiia team. It confirms other reports that also found a poor accuracy at night but good accuracy during the day:

This cuffless Biobeat monitor sticks to your chest. Must be ordered by an MD here in the U.S. It was very easy to use and sleep with (I did a 24-hour cycle last year).

I just saw this (not yet released for sale) and it looks like an interesting and convenient way to check your BP, HR and spo2 while using the toilet. :smiley:

One of the other women on here said she was part of this trial (or a similar item)… perhaps it was @LaraPo ?

That would be great for my father, so I can track his health remotely.
