Rings Of Power

J.D. Power released their 2013 U.S. Tablet Satisfaction Study (Volume 2) and the winner was……. Samsung?  The study is pretty crazy for a couple of reasons. First the categories and their weights are outlined as follows:

Categories
Performance Ease of Use Design Features Cost
26 % 22 % 19 % 17 % 16%

Then in each category J.D. Power gives each brand Power Circles, where 5 is equal to Among the Best, 4 Better than most, 3 About average, and 2 The Rest.  I am pretty sure this is so you have no way of determining how the overall winner is picked.

The amazing thing, Apple scored 5’s on all categories but cost where it scored a 2.  Samsung didn’t score a single 5 on any category but still managed to beat Apple.  Below is a representation of the scores:

Scores
Brand Performance Ease of Use Design Features Cost
Apple 5 5 5 5 2
Samsung 3 3 4 4 4

So to make matters worse, I did a quick check of prices at bestbuy.com to see how drastic the price differences are between comparable tablets and this is what I found:

Samsung Galaxy Note 8 16 GB $399.99

Samsung Galaxy Tab 3 8 inch 16 GB $279.99

Samsung Galaxy Tab 10.1 inch 16 GB $399.99

Samsung Galaxy Note 10.1 2014 edition 16 GB $549.99

Samsung Galaxy Note 10.1 16 GB $499.99

iPad Mini 16 GB $299.99

iPad 2 16 GB $399.99

iPad Retina $449.99 (499.99 at time of study)

iPad Air $499.99

So I decided to come up with J.S Curtis Rings Of Power for Cars and I gave the winner to Yugo the scores were:

Categories
Brand Performance Safety Design Features Cost
BMW 5 5 5 5 2
Yugo 2 2 2 2 5

Today, I decided to release a new version of RF Tools to the App store.  In this version, I am reducing the price to free.  To make up for the price drop, I am adding a tip jar using in app purchasing as indicated in the screenshot.

I will try this for a week or two and see if this generates the same, less, or more revenue.  Since this app caters to a very specific crowd, I don’t expect to see a huge spike in volume.  

 

iPad Mini Take Two

specs_colorLast year I purchased an iPad Mini, it quickly became my main iPad and I couldn’t go back to the full size one.  I sold my iPad 3, but I really wished the mini had a retina screen and a faster processor, it just isn’t quick enough for todays new breed of apps and it’s pretty slow on iOS 7.  So when Apple introduced the iPad Mini with a retina screen and a 64-bit A7 processor my expectations are exceeded.

Apps

Here you will find my collection of iPhone and Android applications I have for sale.  I started getting interested in programming again as soon as I had the first iPhone, it reminded me of the days of the Amiga, the computer I have the fondest memory of, it seemed almost alive.  Anyway, programming for the iPhone is fun, challenging, and it empowers you.

As I get better, my apps evolve with my skill set.  I am totally in awe when I see some of the apps available, there are some truly gifted individuals out there…………..

VSWR Converter

vswr120

VSWR Convert utility allows you to convert between VSWR and Return Loss. You can also calculate parameters based on input and output power

UI updated for simplicity and full support of iOS 7. Change color scheme to match your phone or mood.
