Is Dark Mode beneficial? Is it important?

2019/06/03

MacOS and iOS Dark Mode appear to have niche applications.

It is easier to read black text on white background which makes white text on back background (Dark Mode) kinda unattractive.

However Dark Mode will throw less light into a dark room. Or less light under the covers if you are trying to read in secret at night.

Because it throws less light in a dark room musicians like Ananda Yogiji/Jaya Lakshmi and Ananda should find good use for dark mode during his sets.

iPhone photo download to PC fails to find new photos reset

2019/01/21

Part of my photo archiving is to make something like monthly batches of iPhone photo downloads to my laptop as my primary photo backup before I eventually perhaps once a quarter move the primary archive to a USB drive.

Lately the PC photo import does not find any new photos.

This is the iPhone reset process I found works base on trying things from the following article:

https://windowsreport.com/cant-import-photos-iphone-windows-10/

I did not get to the point of having to use the regedit this last time.

Starting the photo import from the iPhone device in windows finder was sufficient this last time.

Over a year later, how do I use the Apple Watch?

2018/12/18

It interesting how my heart doctor will not recommend the Apple Watch as it is not a medical device however she will look at the medical data it collects for trends in her office.

As far as the ecg feature, my doctor challenged the quality of the single poll ecg. However her comment was the most valuable ecg would be doing an afib event.

Things used in order of frequency

Passive use:

  1. heart rate monitor when running and sleeping
  2. activity monitor of movement, exercise and standing

Active use:

  1. GPS during running (Nike app) and soccer matches to track distance and speed rates
  2. stopwatch when officiating a soccer match. On the same watch I use a count down and count up timers
  3. screening phone, txt and email messages to see if I should pick of the iphone to respond
  4. Apple pay. I’m trying using Apple Pay Cash only on the watch which is discover and often declined so I use American Express on the iphone for the none discover transactions.
  5. Apple wallet for event tickets including Earthquakes and concerts and paperless flight checkin.
  6. quick date reference and a on hand clock device

Sometime uses:

  1. finding the location of my iphone
  2. map directions so I don’t have to look at or use my iphone while driving for turn directions.

Liabilities of the apple watch:

  1. I have to charge it every day.

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

2018/05/23

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 Apple Watch running app

2018/04/02

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

Here are two quotes showing why there is such a difference in apps from this article. https://9to5mac.com/2018/04/02/instagram-apple-watch-dead/

  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 https://www.imore.com/apple-watch-activity-tracking-5-tips-you-need-know:

  1. Workout app from Apple – not sophisticated but always works, limited statistics
  2. Strava works great on the Apple watch with or without the iPhone. It does the mashup with maps well to show coverage and show some simple statistics. However it takes over the watch face during soccer matches and doesn’t seem to work with the heart beat detector built into the app watch face.
  3. 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. Works fine without the iPhone and when I’m doing a regular jog.
  4. Runtastic – fails when not in range of cell phone however I like the stats. I don’t think this guy is native iWatch app.
  5. Moves – passive movement tracker – not on Apple watch only on the iPhone.
