This is the latest addition to the job trends posts, with the last entry back in April. As in all of the job trends posts, I am not going to debate the benefits of mobile operating system applications over generic HTML applications or one OS over another, as that is not the point. The terms included in this list were iPhone, Android, WP7 or “Windows Phone“, BlackBerry, Symbian and WebOS. There is a little noise in the data, but not enough to significantly affect the trends.

First, let’s look at the basic job trends from Indeed:

 

iPhone and Android development continue to dominate the job trends, with BlackBerry hitting a plateau. Interestingly, iPhone demand seems to have dropped off a bit in the past few months. This will be an interesting trend line to watch in the next year. Symbian finally shows a steady decline, though recent announcements could make Symbian gain a little steam if it continues to be developed. Windows Phone (or WP7) and WebOS both show some solid growth as they gain more adoption. Due to HP ending hardware development for WebOS, it will be interesting to see how this affects development demand.

Now, let’s take a look at the short-term trends from SimplyHired:

 

The short-term trends are a fairly close reflection of the Indeed trends, including the slight lead that Android demand currently has. Blackberry had a dip at the beginning of the year, and only slight gains since. Symbian demand is steady, not growing or lessening, while WebOS demand looks to surpass Symbian. One minor difference is that Windows Phone does not really register demand here, contrary to the long term trends.

Lastly, let’s take a look at the relative scaling from Indeed, which shows trends based on job growth:

iPhone demand is still exploding, which diminishes the extremely rapid growth of Android. To put this into perspective, the Android growth is at 50,000%. Obviously, that is a huge number, but it is still dwarfed by the iPhone growth. Windows Phone and WebOS also show some level of growth with Windows Phone around 25,000% and WebOS somewhere below that. Symbian and Blackberry growth do not register on this graph due to the scale of the iPhone growth.

Obviously, iPhone development is still showing strong demand, but Android is gaining steam. I still recommend that you pick up an iPhone development or Android development book. Windows Phone demand is still lagging, so you probably want to wait until the next update in February before learning about it. WebOS may be growing, but you should wait to see what HP does to increase adoption.
