Google does far too little curation of the Android Market, and it shows. Unlike Apple’s App Store, the Android Market has few high quality apps. A study by Larva Labs (the developers of the excellent Slidescreen app) estimates that Google has paid out 50x less money to developers than Apple has. While the Android Market is available in 46 countries, developers can only offer paid apps in 13 countries (for instance, Canada has only had access to paid apps since March 2010). In addition, the price for foreign apps is not displayed in the user’s local currency and developers do not have the option of customizing pricing by country. To make matters worse, you can’t pay for foreign apps using your Amex card or carrier billing. There’s also no support for in-app payments and changelogs (to communicate app changes).
