Phone Apps and devices that regulate your stress levels?

One Éiriú Eolas practitioner told me yesterday about a phone app he has been using, which helped him and his friends notice the benefits or our program, as opposed to others. I thought it was really cool. The only problem is, I suspect that the side effects of constantly using a cell phone for this purpose are actually worse (due to evil waves) than its benefits. But apparently there are other pieces of software you can also use directly on your computer. They help you measure your heart rate and your breathing in real time, as you practice the breathing exercises.

Here is the app he mentioned (EVIL Apple!)

And here's another add-on which you can use on your computer (you may want to watch the short promo video):

Has anyone tried something like this? Perhaps for people who are hardly in touch with their bodies, it is a good way to receive some feedback and adjust their stress levels, until they are able to listen to their own natural feedback better? On the other hand, maybe it's not so good after all, and one should try to learn to get direct feedback from the body without any external help.

But I was thinking that if this is an idea worth pursuing, perhaps one of our techie members could make something similar but better, and for the computer, that we could recommend together with EE. In the program, we could include things related to psychology and diet, small quotes from the authors we like, reminders, etc.

Just an idea, FWIW.

There are a couple of Android apps that I've used before that measure heart rate and stress levels. I'm not sure what, if anything, the ones that claim to measure stress are doing differently than the ones that simply measure the heart rate (BPM); I think they may also take into account how regular the beats are as opposed to just their frequency per minute (and the one I'll link to below also measures for a longer period of time than the strictly BPM app). I looked over the page for the iOS app and from a superficial review, it looks like it may work roughly the same as the Android stress measuring apps.

The apps work by holding your finger on the camera on the phone, then the app turns on the camera and the light and measures the heart rate that way (I don't know the technical details, but it must be measuring some kind of visual difference in the finger that happens with the pulse). From my experience, they appear to be pretty accurate. The apps could also be used with the phone in "airplane" mode, to avoid the EMF pollution.

Obviously these wouldn't have EE branding or anything like that, but they might be a useful resource:

"Instant Heart Rate"

"Stress Check"

Both of these apps are free and are from the same developer company and there appear to be a number of alternatives that I haven't tried.
