App Pricing

J. R. Raphael notes that the current low price of most mobile apps restricts how much support and development can be offered in the future. Raphael suggests that users pay more for apps. My own feeling is that the cost of apps should be kept low, but that support should be on a subscription or "per version" model. I agree with Paphael that indefinite support for a marginal price is not a sustainable model.

Websites Trump Retail Apps

Vijay Ramanan observes that mobile app transactions are far more common in India than in the United States. Ramanan believes that for the foreseeable future websites will be relied upon for commerce , as a Forrester study shows that websites are foundational to the Internet experience, and that apps are perceived as being more biased.

The cited Forrester study shows that 39% of users have only one or two retail apps on their phone, and 21% refuse to download any retail apps (Figure 3). Of those who download mobile apps, 55% use them monthly, rarely or never (Figure 4). So websites are where the majority of consumers go for information.

Mobile Web Technologies or Mobile Apps?

Tomi Ahonen wrote an insightful article on the "Full Analysis of iPhone Economics - It's Bad News. And Then It Gets Worse." The thrust of the article is that hiring someone to develop an iPhone app typically costs $30,000, but the vast majority of mobile users do not have iPhones. He recommends the companies spend a tenth the money and develop mobile websites or SMS campaigns for distributing mobile advertising or information -- strategies that will reach all smartphones and the majority of feature phones with one effort.
