Despite these limitations, the technology has been proven largely reliable and used successfully over the last decade.

Validating the data

In 2017, Altini and a group of researchers, including triathlon coach and multiple-record holder Dan Plews, validated the HRV4Training app against chest strap devices and electrocardiogram methods. The app and methods were independently validated in 2021 in a study that showed high precision for the Oura ring and less reliable results for another app, CameraHRV.

Although this research points toward the strong reliability of the technology, it’s worth noting that the first study involved just 29 subjects, and the second one involved five recruited to perform a total of 148 validation trials. The research also validated the camera on iPhones only, not Android devices. (The app will inform the user if a specific phone is not supported.)

App or program to track health data?
#17

I recommend people try this Guava app.

It seems pretty well designed with a simple onboarding process. Start using it and report on your experience, likes and dislikes.

If you know of others like it, please post.

Something like this optimized around longevity and biohacking would be ideal, but until we get it we have to make due…

Thanks for sharing. Can you import medical records all at once there? (e.g. PDF or Excel spreadsheets)

I’m not sure … I see you can upload the data, but I’ve just installed the app and I’m slowly getting going with it, so will report back when I know more.

Very good chance I missed something, but I see only limited capability to import values from excel.

First, you have to convert excel to .csv. And then only a date and a limited set of data types are supported. And your data values have to be vertically oriented.

I didn’t actually try to import anything, the options offered weren’t appropriate.

It took a few minutes, but I successfully imported 21 years of data from Kaiser.

I also imported my labs from patient.labcorp.com. I hadn’t thought about it until I was on the import screen, but all your lab reports you ordered via Marek are also available on the patient.labcorp website, just have to create an account.

Lastly, I imported Dexcom G7 data.

Just another data aggregator, is my initial impression. The ‘chronic conditions’ thing seems like a maketing statement. But only my vague first impression.

This is useful to me as it

  1. makes most of my Kaiser data easier to peruse, compared to the Kaiser website.
  2. chronologically integrates the Labcorp labs with Kaiser labs

I’ll still maintain a spreadsheet, as it is just easier to eyeball data across time and across labs on a single screen.

21 years of data uploaded in a few minutes - wow, that seems pretty amazing. Let us know how well it works for you. its a fairly new product I think, so there are bound to be bugs.

Another interesting App, from Google:

Jim Taylor, a research scientist with Google Health, knows a thing or two about taking temperatures. That’s because in addition to his role at Google, he’s also a pediatrician. “The first thing I ask a parent when they call and say ‘My child has a fever’ is ‘What’s their temperature?’” he says.

For six years, Jim has been part of the team at Google Health working to bring health tools to Pixel phones. One of the first of those tools is the new body temperature feature in the Thermometer app for Pixel 8 Pro. Part of the January Pixel feature drop, it allows you to quickly scan a person’s forehead with your phone and measure the body temperature. In clinical trials, our software algorithm was able to calculate body temperature in the range of 96.9°F - 104°F (36.1°C - 40°C) to within ±0.3°C when compared with an FDA-cleared temporal artery thermometer. In layman’s terms, this means the Pixel body temperature feature is about as accurate as other temporal artery thermometers.

Here’s something else I found interesting from the Withings company - a home body weight smart scale that measures Pulse wave velocity of blood. Seems kind of like a home CAC (coronary artery calcium) test.

And here’s more about what PWV is:

There’s a reason smartwatches haven’t replaced clinically validated gear when you visit the hospital — accuracy and reliability are paramount when the data informs medical procedures. Even so, researchers are looking for ways in which these devices can be meaningfully used in a clinical setting. One project in the UK has explored if a Garmin Venu 2 and dedicated companion app could be used to free up doctors and nurses, six minutes at a time.

The Six Minute Walk Test (6MWT) is used to diagnose and monitor a number of cardiovascular maladies. This includes conditions like Pulmonary Hypertension that, if left untreated, are eventually fatal. “[The test has been] a cornerstone of hospital practice and clinical trials for decades all around the world as […] a marker of how well the heart and lungs are working,” project leader Dr. Joseph Newman told Engadget. While a change in a blood test marker might be clinically relevant, he said “it’s probably more important to someone that they can walk to the shop and back.”

The test requires a patient walk on a flat, hard surface for six minutes straight, which stresses the heart enough to measure its capacity. A professional tests the patient’s heart rate and blood oxygen levels at the start and end. While it’s simple and reliable, “it’s not perfect,” according to Dr. Newman. “This is why we’ve looked to change it in two important ways,” he said, “can we make it shorter […] and digitize it for remote use?”

After all, six minutes is a lifetime in a clinical setting, and patients dislike having to schlep all the way to their hospital just to walk up and down a corridor. It’s why Newman and Lucy Robertson — both researchers at the Royal Papworth Hospital in Cambridge — began looking for ways to revolutionize the test. They wanted to see if the test could be shortened to a single minute, and also if it could be carried out by a patient at home using a Venu 2.

Goes along with something that I saw on the internet that said - When you’re out and about, just look around, you can tell how long somebody will live by how fast they are walking.
Ever since then, I’ve walked a lot faster.

Dexcom’s first-ever over-the-counter glucose monitor patch gets FDA clearance
#29

The sensor will be worn on the upper arm, and it lasts for up to 15 days before it needs to be replaced, according to Dexcom’s website.

(Prior ones from Dexcom have onlu been 10 days)

The platform will be tailored for the needs of these Type 2 patients, he said, which means it will not include many of the alerts and notifications meant for diabetes patients at risk of experiencing more serious emergencies.

“It’s designed to be a simpler experience,” Leach said in an interview. “There’s a lot of people who could benefit.”

Leach said as Dexcom is able to demonstrate the benefits of Stelo, the company believes insurance companies will eventually pay for it. He said Dexcom decided to get the product out to the market at an “approachable” cash pay price first to help get it into users’ hands quickly.

“I think it’s important for people to have that insight — it’s like a mirror into their body,” he said. “It’s very personal.“
