Health records in a cube, an apple iPhone cube from the HL7 FiRH Argonaut project


This is the project that has my interest presently.

Your iPhone can become the health record cube of science fiction.

This is the vision of the apple health app. A place where google is not yet publicly competing.

Today I finally found the article about this secret apple project which might sometime involve Human using FiHR and EMR from multiple vendors.

Which is the best iWatch running app


I’ve been having difficulty picking which running app I want to use on the iWatch.

Here are two quotes showing why there is such a difference in apps from this article.

  1. “For apps like podcast players, creating a truly first class experience isn’t possible today due to limited developer resources — Apple’s apps have more privileges than third party apps”
  2. “watchOS app updates must be native starting this week which means we’ll likely see a lot of older Apple Watch apps disappear with future iPhone app updates starting now. Instagram for Apple Watch was built during the original cycle of WatchKit 1.0 apps where functionality relied completely on the paired iPhone.”

Here is my current order of preference and why. All the below apps show in the iPhone “Activity” app described here

  1. Workout app from Apple – not sophisticated but always works, limited statistics
  2. Nike+ came with my iWatch model – OK, but I can’t get the app totally silent so I can use it on the soccer pitch.
  3. Runtastic – fails when not in range of cell phone however I like the stats. I don’t think this guy is native iWatch app.
  4. Moves – passive movement tracker – not on iWatch.

First wrist watch in 10 years is an Apple Watch.


Apple Watch for three reasons:

  1. I needed a digital watch to use during my officiating. It turns out iWatch is popular among referees.
  2. It takes your heart beat! I’m using the app Cardiogram to get cool 24 hour graphs of my heart beat.
  3. I can follow txts and phone calls without taking my phone out of my pocket.

Bonus is using the wallet on the watch to get into quakes games from my wrist.

Bought at mothers day discount on Friday, May 12 at Best Buy.

Why facetime audio is so much better than making a mobile carrier phone call


I kept struggling to figure out why technically facetime audio is so much better that making a Mobile phone call.

At last I found the explanation.

AAC-ELD audio protocol an AAC-LD based technology.


FaceTime Audio: The Beginning or The End?

I can’t understand my Dad on mobile however on facetime audio he is very clear.

Trying out Google photos, the remnant of Google+


it’s a trade off. 

The stories are nice and shareable. 

The face recognition works at many levels. I’ve found a couple of miss placed faces however there are more finds than miss identifications. 

So with all those photos Google gleans from cookies when my photo types are browsed by me or others that I have given access. › 2015/05/31 › uh-o…
