Meet the mobile app developer middle class (Hint: You may be part of it)

We all know who the upper class in the mobile games space includes. There are the Zyngas, the Kings, the Rovios and a handful of others.

Top 3 wishes for Android M

I've heard "marshmallow," "marmalade" and everything in between, but this is the only thing I know for sure: Even if it might resonate with app developers, it is highly unlikely the "M" in Google's upcoming Android M operating system will stand for "monetization."

Google I/O 2015 Special: Material Design, one year later

When developers walked into Google I/O last year they were probably expecting updates to Android and some additional tools, but the introduction of its Material Design guidelines was something of a surprise.

A/B testing on Google Play: Some thoughts on the big rumor swirling around I/O 2015

Sometimes, like many other men trying to dress to impress, I will stand before my wife--or even one of my children--with two different ties. "Which one do you like better: this one or this one?" I'll ask, giving them a choice between colors, patterns, or often both. Depending on the nature of the meeting I'm going to, I may follow up with questions like, "Which one says 'knowledgeable' or 'creative' to you?"

The question facing app developers following Microsoft's latest 'universal app' invitation

When you're the third choice--and a distant third choice at that--the only option you have is to be the best third choice imaginable. That, in essence, is what Microsoft proved with the latest plank in its "universal app" strategy.

What Google App Indexing will mean for the future of Android app discovery

When you enter the search term "Android apps" in Google, what you mostly get back are lists. "Best free Android apps," for example, along with some headlines from Google News and a direct link to Google Play.

The rookie mistake developers can't afford to make with Apple Watch apps

Of course, I expected the recent launch of the Apple Watch to be a big day for developers. I knew many of them would try to make good use of the product's availability as an opportunity to introduce new apps and games. Rather than a major step forward into the future of technology, however, the whole thing took me back more than a decade into technology's past.

App video tutorials: The why, the how and the who

In an ideal world, developers would be able to sit down with each new consumer who downloads their app or mobile game and explain how it works and the best way to get started quickly. Since we do not live in an ideal world, we have video tutorials instead.
