Invisible App Downloaded More Than Visible App?!?



Okay this is weird!

I’m learning about app marketing and they say you have to optimize to rank higher in app store search results. Otherwise how will people find your app?

My first app, Weight, is nearly invisible in iTunes. It’s a crowded market. I didn’t know the best practices. I’ve appeared in only 91 search results. It’s almost invisible.  But I’ve had over 1700 downloads.

For my second app, Vital Signs Blood Pressure Log, I applied “App Store Optimization” best practices. It’s a success in that it has already shown up in 6X as many search results and it has only been available a couple of days. But it has fewer than 10 downloads.

It’s just weird!?!





TIL – You Have to Segment Your Market

Today I Learned you have to segment your market. I built my app to learn how to navigate the Google Play and Apple App Stores. But being forced to write the app store description is making me learn about marketing. It’s also making me change the app to make it useful to each user.

I have to ask, why should a potential user choose my app instead of the countless others?

The Person Who Wants to Watch Their Weight (Generic User)

The Person Who Wants to Watch Their Weight is my generic user.  Apparently I don’t know them well enough.


The Athlete

The Athlete competes in weight classes. He has to keep his weight within a range or he’s thrown into another weight class. That’s bad. He’s going to need an app that works well in a crowded locker room. Big buttons. Big User Interface. A way to see where he is on the scale and if he’s going stay within his weight class.


 The Expectant Mother

The expectant mother is excited. She’s doing yoga. She may weigh in at the yoga studio or at home. She’s going to want to know how much she is gaining and losing over time.


So much to learn! But it’s making the app better. Have you checked out the app?

How to install Kdenlive 16.08.3 on Centos Linux 7.3

One of the great things about Centos Linux (aka Red Hat Enterprise Linux, Oracle Linux) is the packages are stable and mature.

Unfortunately, that also means current versions of a package may depend on libraries that aren’t officially in Centos yet.

Case in point:  I had to reinstall Kdenlive. The current version (16.08.3) depends on libraries that aren’t available. You’ll think the package is broken. And the version of Kdenlive that shipped with Centos 7.3 won’t start. So if you have a video to edit, it’s time to panic.

So, for others in the same boat:

  1. Install the repo with the current version of kdenlive
  2. Install the current kdenlive
    sudo yum –enablerepo=cr install kdenlive

Result: kdenlive will start but some icons will be missing.
Fix it with sudo yum install breeze-icon-theme


Why is reading an ebook on Linux so complicated … and ugly?!?

Linux needs an ebook reader

When I’m doing research some of the sources are ebooks so I’m looking for a way to read books on my Linux laptops and desktops.

On Android and iOS phones and tablets, this problem is solved beautifully. The stock iBooks app and Google Play Books app are excellent. After trying A LOT of book readers, I recommend Moon+ Reader.

Simplicity Counts

Even though I’ve paid for Moon+ Reader Pro I catch myself firing up Google Play Books precisely because it has FEWER options. You can tell Google put a lot of work in to making it simple.

Recommendation: None

On Linux, I still haven’t found a satisfactory solution. In fact, if I need to read more than a page or two, I’ll send it to my phone. It’s crazy but it’s more pleasant to read on a small-screened phone than on a powerful Linux machine with a huge monitor.


  • MUST – The ebook reader MUST meet ALL of these requirements.
  1. MUST work in Linux
  2. MUST work offline
  3. MUST allow changing font-size.
    (To deal with high-DPI displays, poor book formatting, poor eye-sight, etc.)
  4. MUST work with epub
  • SHOULD – The ebook reader SHOULD meet these requirements but they are not deal-breakers.
  1. Should be able to open book directly
    (I should be reading the book after I double-click in the file browser. I shouldn’t need to ‘import’ it into its own custom library or convert it to its own custom format.)
  • COULD – The ebook reader COULD meet these requirements but they are not deal-breakers.
  1. COULD work with mobi
  2. COULD allow changing font
    (There’s a lot of Comic Sans out there)
  3. COULD work with chm


These are features I don’t care about and not part of the selection process.

  1. Library ‘management’. I have Google, Apple, and Amazon telling me about the book and the authors and a computer that can full-text index my books. Why would I want to spend time ‘managing’ my library?
  2. PDF. There are a lot of excellent PDF viewers out there. I don’t need my ebook reader to show me PDFs.
  3. Conversion. As an end-user, I just want to read my book. Why would I want another copy in another file format to manage?

Individual Reviews


  • This is the ebook reader that’s stayed on my computer the longest. It uses my font-size settings. It’s not a deal breaker but I still cannot simply open a book by double-clicking on it. I have to ‘import’ it into its library.
  • Deal-breakers
    • None
  • Available at: Readium

Simple EPUB Reader

  • This is so CLOSE! It’s a delight to use but it ignores your font-size setting.
  • Deal-breakers
    • Can’t change font size. Overrides your font-size setting for the ones that came with the ebook. So if you’re working with a hi-dpi display or you just need a bigger font, you can’t read the book.
  • Available at: Simple EPUB Reader

EBook Offline Reader


  • Deal-breakers
    • Can’t change font size. Overrides your font-size setting for the ones that came with the ebook. So if you’re working with a hi-dpi display or you just need a bigger font, you can’t read the book. 
  • Available at: Readiator EPUB Reader


  • This is the program everybody raves about. It is its own web server, book-management library system, book converter, ebook-sync manager, ebook editor, news and magazine aggregator. It has its own custom icons, menu-ing system. Everybody raves about it but it’s not for me. I just want to read a book.
  • Available at: your Linux distribution, i.e., yum install calibre


  • Close. But it wants to be your book-management library system. The custom icons aren’t for me.
  • Available at: your Linux distribution, i.e., yum install fbreader

Not Short-listed

These were tested but did not make the short-list:

  • Lektz – Could not open test epub
  • Cloud ePub reader – this ‘free’ reader says I have to disable adblock for free use
