Cardiogram

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

I use a fitness tracker called MIO Fuse - it's a great сontinious Heart Rate Monitor, but Mio has very painful and useless both Android and iOS app. I wish to have access to raw…

Thank you so much, I had hoped that there would be something like this inbuilt with motofit/google fit but was quite disappointed when I discovered how inadequate and manual it…

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…

Photoplethsymographic heart rate requires a lot of algorithmic compensation for noise and motion artifact. There are some pretty sophisticated strategies available for beat…

Even the standalone optical HRMs (e.g., Scosche RHYTHM+) aren't good enough to do HRV[1] even though their accuracy compares favorably with the chest strap models[2] [1]…

OP - I love the concept, but the execution isn't there. I installed it on my Gear Live, and it pops up a "Heart Rate" notification, that until acknowledged leaves the heart rate…

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…

I'd love to hear some thoughts on how this affects battery, especially on some battery-challenged devices such as the moto360 ?

Cool! How soon until you can tap into a calorie app/database (MyFitness?) and start to guesstimate the user's caloric burn rate each minute?

I use a fitness tracker called MIO Fuse - it's a great сontinious Heart Rate Monitor, but Mio has very painful and useless both Android and iOS app. I wish to have access to raw…

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?

How does this work on Apple Watch? AFAIK, WatchKit doesn't give access to the heart rate sensor.

Hey Brandon, I'm doing usability research at Virginia Tech on EEG's and EKG's. I'm trying to figure out how to do continuous heart rate for Apple Watch for an app/study. How are…

I have a Fitbit Charge HR that checks every second during exercise and every 5 seconds otherwise. The battery lasts about 4 days for me. https://www.fitbit.com/chargehr

Suunto's watches have done that for a while now (5-6 years?), though they use a capacitive chest strap, rather than the optical method used by smart watches. Edit: And as far as…

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!
