Bulky requires cuff calibration

This might’ve been a little useful 10 years ago, but when we have things like Apple watches and Oura rings, it is silly and useless. Why wear a bulky black Velcro band with a hard tracker inside when there are much smaller or more stylish options especially when those other options give you so much more than a heart rate reading. Also have to calibrate with an actual blood pressure cuff on the arm.

Defective Cuff and No Real Support

was genuinely interested in the Hilo system. Continuous blood-pressure tracking with a wrist band plus occasional calibration sounded like a practical step up from spot-checking with a traditional cuff, and I went in expecting to use it long-term.
Unfortunately the included upper-arm cuff never worked reliably. Readings jumped all over the place or the unit simply wouldn’t complete a measurement. On multiple occasions the cuff kept inflating well past a normal cycle—sometimes for minutes—until my arm was numb and I had to stop it myself. Because the cuff is required for initial setup and ongoing calibration, a non-functional cuff made the rest of the system unusable from the start.
I contacted the company, explained the problem clearly, and offered to ship the defective cuff back in exchange for a replacement so they could inspect it. I received no meaningful response. For a product that depends on that cuff and requires an ongoing subscription, the inability (or unwillingness) to simply swap a clearly defective component was a deal-breaker. I cancelled and moved on.
I’ve since switched to a Garmin cuff and have had consistent, trouble-free readings. I still like the idea of what Hilo is trying to do, but a device that doesn’t work out of the box combined with unresponsive support isn’t something I can recommend.

Great, but….

…. this is a tremendous wearable to monitor how your blood pressure changes, and I’m very, very impressed. However, I have two other blood pressure monitors, both well thought of, and both of them cuffed based. They consistently give me lower blood pressure readings than does the Hilo. The highlow readings are about anything from 5 to 10 points higher than the other two calf readings. Both the other calves give comparable results. I wish there was a way we could alter the results so that they gave a better, more accurate reading of daily blood pressure changes. Nevertheless, I recommend this to anyone concerned about their blood pressure or has heart issues.

Set up flow is broken

I cannot set up my Hilo even with the help of support. The app is broken in several places. The location screen is broken. The email confirmation is broken. Terrible experience

Not Changing

Charged up the first time then it would not charge again so I got one charge worth of history.
