Is there any watch on the market that has enough battery to do real continuous HR monitoring? Last I checked, they all only measure continuously in the "sport" mode for an hour or two, and in the "regular" mode they measure HR once every 10 minutes or so.

I have the Samsung Gear 2 Neo, and tried building an app to record HR all day sampling once per second. A full battery lasts about 12 hours in this condition. However, the heart rate monitor subsystem crashes fairly often, and gets very inaccurate with pretty much any arm motion. So not super useful. Basis, Amiigo (not yet for sale), and even Epson have wrist-based trackers which claim some form of continuous heart r…

I have the Gear Fit and while it doesn't crash, the sport mode is very inconsistent while running. Tightening the band might help but it's uncomfortably tight.

Capturing HR once a minute is of really limited use. More than benchmarking against resting HR, the interesting thing is to look at heart rate variability, and to do that you need to scan several times per second. For that using purpose-built devices is just better. I am thinking: https://jawbone.com/store/buy/up3 or http://www.getqardio.com/qardiocore-wearable-ecg-ekg-monitor...

I thought the Up3 only measured resting HR.

We do indeed sync the data to Google Fit—so it both reads your activities (walking, running, biking) from Google Fit and any connected apps you have, and writes the raw heart rate measurements back to Google Fit.

Cool. I just realized who you are. Taking time off from healthcare.gov?

Oh! I wrapped up my involvement last fall. It was a 2-month rotation that became 3 months, then 5 months, then 8 months, ...

After taking a couple months off, I started collaborating with some UCSF researchers--we know that in the next few years, millions of people are going to be wearing heart rate monitors. But what does that mean for healthcare? Can we actually detect things like heart attacks or lethal arrhythmias before it's too late? Could we potentially build the "check engine light" for your heart?

So that's what this app is a first step toward.

You are right. A few months ago Jawbone UP3 definitely had HRV listed in the heart health features. That's specifically why I was looking to buy it. I guess that's close to impossible with an optical sensor.

An app like this could save a life one day, for sure. My uncle recently died from a heart attack. It's impossible to know for sure but perhaps if he'd been wearing a smart watch, it could have told him to seek help before it hit.

I'm not a doctor, but based on what little research I've done in the past, a basic heart rate monitor such is this is unlikely to provide any pre-warning of a serious cardiac event.

I'm curious about the privacy aspects of it. Can anyone elaborate on where and how the data is stored?

In a related question, does anyone know of any monitoring product (e.g. FitBit or whatever) that does NOT send your data to a centralized server outside of your control?
