A Survey on Mobile Development

by Abel Avram on May 05, 2011 |

Web Directions conducted a survey among mobile developers enquiring about their browser and platform of choice, what OS they are currently developing for, what OS they plan to target in the future. The conclusion: iOS and Safari are in the lead, Android is catching up quickly, and Windows Phone 7 is still behind.

Web Directions, an Australian web technologies-related conference organizer, has conducted a survey on web technologies during the month of February, and has published the results on mobile development, the rest of the results being promised to come soon after. The audience of the survey consisted mainly of “our online audience of people who are interested in or have attended our conferences for web professionals, read our blogs and twitter feeds related to web technologies, and take our courses in web development technologies”, so the results of the study may not necessarily accurately reflect the reality, but they are good enough considering the size of the sampled audience, 1,500 developers, and their global spread, according to the authors.

Browsers

Asked what browsers they use besides the regular one used for work on a desktop or workstation, the developers responded:

Android 11.79
Opera Mini 2.27
Opera Mobile 1.83
Palm 0.3
Windows Phone 7 0.15

iPad 71.6
Android Phones 60
Android Tablets 47
Windows Phone 7 23.9
Blackberry 16.5

Regarding the type of technologies used to develop native apps, the developers responded:

Technology %
A mixture of native and web technologies 44.8
Exclusively native technologies (Objective-​​C, Java) 39
Exclusively web technologies (with phoneGap, or similar) 27.4
Appcelerator or similar cross platform development tool 19.7

PhoneGap and Appcelerator top the list of web technologies used for native mobile applications:

Web Technology %
phoneGap 47.6
Appcelerator 26.5
Other 15.6
Adobe AIR 7.8

The survey compares data collected in 2011 with that resulting from similar studies done between 2008-2010, showing that iOS has the lead in mobile development and developers’ preference, but Android catches up rapidly. Windows Phone 7 has a disappointing perception amongst developers, but its position is likely to get better in the future.
