The policy "would make sense for expensive, involved productivity apps; if the user is unsatisfied with the product, paid good money for it but won't be using it, then a refund is warranted," Watkinson wrote. "However, for many fun apps and simple games, the user isn't expected to get more than a day or so of use out of it."

Larva Labs pointed out the deficiencies of the Market as possible explanations for why it is earning so little money selling apps in the store. It has two high-ranked games in the Android Market but is averaging US$62.39 in sales per day. The company compares that to some of the well-known success stories in the iPhone App Store, where developers of popular applications have earned hundreds of thousands of dollars.
