Google in October 2008 launched Android Market, an app store for its Android cell phone operating system platform that enables users to download applications along with the first Android-powered phone, the T-Mobile G1. Users can rate the apps they've downloaded and leave comments on the site. Google says the ratings, along with anonymous usage statistics, will help determine how apps are ranked and presented within Android Market.
In February, Google announced that the store had begun accepting priced applications from U.S. and U.K. developers, in addition to free programs. Developers from those countries can upload their applications along with pricing for the applications. Google says it will enable developers in Germany, Austria, Netherlands, France, and Spain to offer priced applications before the end of March. Applications available on Android Market include multimedia, location-based tools, barcode scanners, travel guides and games.
Microsoft Corp. at the Mobile World Congress in Barcelona in February launched new Windows phones as well as Windows Marketplace for Mobile, an application store that will provide direct-to-phone mobile apps and can be accessed from both the phone and the Web.
Microsoft says the new marketplace will be included with all Windows phones based on Windows Mobile 6.5, which will help users easily find, install and deploy applications. Developers have already built more than 20,000 applications for Windows phones, according to the company.
Nokia also launched a mobile app store, the Ovi Store, at Mobile World Congress. Beginning in March, content providers and developers can begin uploading content to the store, which will open in May. Nokia says applications will include games, videos, widgets, podcasts, location-based applications and personalization content for Nokia Series 40 and S60 devices.
