Hey! I'm the OP. Let me know if you have any questions. Just for fun, this was my heart rate while launching this: https://twitter.com/AppCardiogram/status/591377862441046016

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 rate monitoring. The Epson in particular seems interesting, as they developed the sensor in-house with a focus on power management; they say it can record continuously for 40 hours.

Does Google Fit handle heart-rate data? It'd be great if I can access my data there. Nice work! I've been looking for something like this.

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.

I've been using Cinch up til now; it would be great if Cardiogram sent the data to Google Fit to graph like Cinch does!

It does send the data back to GFit! Warning though—the GFit graph isn't necessarily built for this resolution of data. That's part of why we built our own chart to show you the details.

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

We have servers that store the raw data and run the algorithms on it, and then it's also synced to Google Fit (on Android) and HealthKit (iOS).

Cool.

I just realized who you are.

Taking time off from healthcare.gov?

That's great to hear! I barely touch Google Fit myself; I was more wondering about it because I use Google Fit to send HR data to gyrosco.pe.
