Samsung ‘Galaxy Active’ Smartwatch Blood Pressure Capability NOT Ready For Prime Time Nor My Wrist.

by Anura Guruge



Click to ENLARGE. It will be a NEWER version of this APP.

I started doing some serious research into this Samsung Galaxy Active smartwatch ‘Blood Pressure‘ capability and soon discovered that it is far from satisfactory.

Basically it will be the same as that currently available with the Samsung S9(+) smartphones and this capability, on the phone, has not been a great hit.

There are 3 BIG negatives:

  1. You can’t (unlike say with heart rate) get a reading on the watch. A reading is ONLY available on the APP. So, it is a ‘connected’-feature. You need the phone, at hand, to see a reading.
    …..
  2. It CANNOT measure absolute values! It can only measure CHANGES from one reading to another. That is relatively useful BUT nowhere as good and relevant as getting an actual reading that says ‘117/70’. This is my biggest gripe.
    Then they TRY to fake it. They want you to enter a baseline value taken with a proper cuff or what you last got when you saw your doctor. Then it uses that to correlate its first reading. That is GARBAGE. Blood pressure readings change from minute-to-minute. I know. I am somewhat of an expert on this matter.
    So, taking the baseline as corresponding to the first reading it is taking is INVALID. The baseline & first reading could be +/- 20% out. Possibly even more.
    So, the absolute readings the APP gives are meaningless. They could actually be DANGEROUS. They could be way too high or way too low.
    ….
  3. The APP is not from Samsung. It is from a 3rd party and the current version has not been great.
    ….

So, I am thinking of holding back on buying a Samsung Galaxy Active.

The BP feature is only going to be available as of March 15, 2019. I am going to see what the reviews are. OK?

I suggest you do the same.

‘SplendCare’ Portable ECG/EKG Monitor, At $79, Better Than $99 KardiaMobile.

by Anura Guruge



Click to access Amazon listing.


Two ECG traces — one from SplenCare other from KardiaMobile.

Notice, they look very much alike. That is GOOD.


Click to ENLARGE and read here. My 5-star review at Amazon. Use link above to get to Amazon listing.


OK, I am lucky enough to be able to have BOTH, the $99 AliveCor KardiaMobile & the $79 SplendCare unit.

As you can see from the two plots above the readings I got from the two, despite the $20 price difference, is very much the same.

Given that equivalence, I have to say that I prefer the less expensive SplendCare unit more, and it would be the one that I recommend.

What is my main reason. Bluntly put, much less hassle. SplendCare, with its cute, built-in screen, is a standalone unit. Take it out of the box, charge it and BANG you get a reading. You don’t have to download an APP, register, wait for a doctor to do the first reading etc. That is way cool. Plus, unlike the KardiaMobile it is not obnoxious. With the ‘Kardia’ it is always ’10 questions’ before you can get started. Not so with the SplendCare. Pleasure to use.

Yes, I did install the Windows APP. Easy enough. And downloading the ECG readings via USB was a piece of cake. So, that is the key theme …. easy, easy, easy. I liked it.

If you need a ECG unit get the SplendCare for $79. Money well spent.

I have been meaning to show YOU this comparison for a few days. Never had the time. Made a point of taking these two pictures, from the same place to show YOU the difference.

Pretty impressive right? Pretty amazing.

This was taken outside, at 6:19pm, on Halloween — with no street light, and bare minimum ambient light from a house.

It was PITCH BLACK! I kid you NOT.

Nothing but BLACK.

So, all the green, orange, yellow and blue were ‘caught’ by the APP.

This is amazing.

Installing The Google Pixel 3 Camera APP With “Night Sight” On A Pixel 2.

To get ‘Night Sight’ You Need The Pixel 3 Camera APP (CameraP3).


You will get the ‘NIGHT’ button on the P3 APP.

The ‘Lifehacker‘ instructions for getting the Google Pixel 3 camera APP (above) WORKS.

I used them. They worked.

Some small modifications you can make, if you so wish. You can get to Chrome’s ‘Advanced Settings’ from phone’s SETTINGS → APPs → Chrome → Advanced. I just found that easier.

It is a BIG download. So, it will take some time. Installation was pretty straightforward and easy. There were no ‘gothchas’.

Enjoy.

Thanks ‘lifehack’. (I hope this APP is safe!)

Google Pixel 2 “Night Sight” (Borrowed From Pixel 3) Is Just Insane — Taking Pictures In The DARK!

You need to get Ver. 6.1 of the ‘Camera’ App from Google Play.


I read that this ‘Night Sight‘ feature, from Google Pixel 3, had been made available for the Google Pixel 2, this morning, with a brand new update to the Camera App.

I went and downloaded the App. Yes, it was at 6.1 — which was supposed to be the requisite version.

I waited until it was dark to try it out.

IT IS SCARY.

The last 2 pictures, above, were taken in DARKNESS. I could NOT see the lighthouse or Buzz. I kid you not. The first picture had some reflected light from my PC monitors. No other lights in the room. This is AMAZING.

I am going to try this out further.

ECG/EKG Heart Monitoring On ANY Apple Watch With AliveCor’s ‘KardiaBand’.

by Anura Guruge


Click image to ENLARGE.

 



Link to AliveCor’s product page.


This is pretty clever BUT, at present, too limited in that it ONLY works with Apple Watches & exploitatively priced!

It is definitely worth $99 and I say that as somebody who just a month ago bought a $99 ‘KardiMobile‘ that works with BOTH Android & Apple and does NOT require the $99 Premium Membership.

IF they make one that is Garmin compatible and does NOT require the Premium Membership I will get one — as long as the strap is not too ugly.

Great idea. Poor execution.

I have noticed this with AliveCor. They seem DESPERATE for cash. Continually trying to get you to buy membership.

I am not sure what the PATENT situation is with this technology. I would LOVE to see others enter the arena and make an effort to work with Garmin.
