As part of our ongoing research into iPad and media, and also to provide some insights for the audience of the iPad Strategy Workshop we ran at Newspaper Publishers Association, we created a visualization of the top 30 paid and free iPad apps in Australia, as of 24 August 2010.
The chart shows in the left hand column free apps, and on the right hand side paid apps, each ranked from #1 to #30 in order of popularity on iTunes. The following bar shows the price (for paid), the user rating on iTunes, and the size of the download in MB. The horizontal axis for paid apps indicates price.
The color code shows the type of app, bringing to attention a number of interesting features, for example that aggregators are very popular in paid apps, and that broadcast and newspapers dominate in free apps.
