Just like the Omron Evolv ($75), the blood stress cuff has the electronics embedded within the cuff itself. That may make it somewhat awkward to make use of, particularly in the event you don’t have a very large arm. Aktiia additionally instructs you to make use of the cuff on the other arm from which you’re carrying the band. You can also’t use third-party BPMs to calibrate the cuff, to make sure Aktiia’s touted accuracy. (The Hilo was FDA-cleared in 2025, has been examined and reviewed in a number of clinical-grade studies over a number of years, and meets the ISO 81060-2 normal for validating the accuracy of blood stress screens.)
A daily BPM cuff measures your blood stress, or how onerous the blood presses towards your vessel partitions, by inflating the cuff to quickly cease blood circulate. Your physician, or these days a digital oscillometric detector, then listens for when the blood stops and begins flowing in your veins; the very best measurement is your systolic BP, and the bottom your diastolic.
As an alternative of making use of stress to your blood vessels, the Hilo band makes use of the identical photoplethysmography (PPG) optical sensors which can be already in most health trackers to research the heartbeat form of the arteries beneath your pores and skin. It then makes use of its proprietary algorithm to measure your blood stress a number of instances a day while you’re at relaxation.

In case you don’t already know you may have hypertension, it’s simply not a factor that many people would possibly assume to examine. I’ve glorious blood stress each time I’m going into a health care provider’s workplace, so why would I ask if I can take my blood stress mendacity down or in a single day?
The Aktiia Hilo is extraordinarily useful as a result of I can see my blood stress dropping whereas I sleep. It additionally takes the common of your BP measurements all through the day, fairly than spot-checking at intervals. Some folks, like my husband, have low blood stress it doesn’t matter what they do. Mine can spike if I learn the unsuitable e mail, if I’m barely dehydrated, or if my ankles are crossed once I’m measuring it.
I cross-tested this with the Withings BPM Vision and located that the outcomes tallied; nonetheless, it’s good to have the ability to measure with out taking half-hour out of your day to take a seat and put together.
Now that the Apple Watch has improved its battery life and you’ll put on it for twenty-four hours a day, it might additionally monitor your blood stress at evening. (The new Whoop band additionally purports to supply hypertension notifications, however it’s notable that the Whoop has not tried to clear the function with the FDA.) However the Apple Watch can solely search for patterns over a interval of 30 days. It doesn’t supply constant systolic and diastolic readings that your physician can examine.
