Now that there are apps for three different devices- iPhone and iPod Touch, iPad, and Mac- we can compare the prices of these apps against each other. This concludes that Mac apps are very pricey compared to iPhone and iPad apps; in fact, they are cost 7x as much as iPhone apps and 3x as much as iPad apps. Studies also show that 11% of Mac apps are free, compared to 33% of iPhone apps.
The Mac App Store is also not as popular as other app stores. 2 months since launch, it has 2,225 apps. 2 months after the launch of the iPad, there were 8,099 apps avaliable. Yet more studies have calculated the average price of apps for all three devices. These are $1.57 for iPhone, $4.19 for iPad, and $11.21 for Mac.
I have to say, however, that these prices will probably drop. Designers making the first apps to appear on the Mac App Store probably thought that they could bump up the price a little, as they didn't have as much competition. Now that the number of apps should soon hit 4,000, designers will have to reduce the price of their apps. However, Mac software is far more complicated than iPhone software, so expect average prices to stay above $8.
