Apple’s App Store pioneered the managed mobile application marketplace, even though Apple is one of the last major players to enter the smartphone race. App Store has so far surpassed expectation with its billion downloads recently and is one of the major differentiating feature of iPhone compared with other smartphone platform.
The overwhelming success of App Store spurs other vendors to develop their own store in order to compete. In case you are confused by the different naming for app stores, here is the list of Apple App Store’s competitors:
### App World
BlackBerry launched App World in Apr. [Visit the store.](http://www.blackberry.com/appworld/)
### Android Market
[Android Market](http://www.android.com/market/) for Google Android based phones was launched in Oct 2008, with the availability of paid apps from Feb this year for US market.
### App Catalog
This could be the name for Palm’s app store for its webOS devices, nothing is confirmed until Palm Pre’s official debut, which should be anytime now. But there is no indication if Palm’s app store will be available together with the launch of the first webOS phone.
### Ovi Store
Nokia’s Ovi branding is more than just a store, [the Ovi website](http://www.ovi.com/) encompasses other phone services such as contacts and calendar sync to the internet cloud, similar to what is being offered in MobileMe and Microsoft’s MyPhone.
Nokia on Monday [began rolling out its Ovi Store](http://www.reuters.com/article/internetNews/idUSTRE54O2MI20090525) to production servers, and is live today worldwide for Nokia phone owners. TechCrunch took a spin and called the launch [a complete disaster](http://www.techcrunch.com/2009/05/26/nokia-ovi-store-launch-is-a-complete-disaster/).
### Windows Marketplace for Mobile
Microsoft has yet to launch its Windows Marketplace for Mobile app store for Windows Mobile platform, but you can’t help but notice the store has the longest name among all the app stores, just like most of other Microsoft products. We suspect the branding is from the same marketing team behind Windows Vista.
Too many app stores for our money indeed. Will there be app store from Sony Ericsson or even Motorola?
Updated June 03, 2009 – Sony Ericsson [announced their PlayNow Arena app store](http://www.sonyericsson.com/cws/corporate/press/pressreleases/pressreleasedetails/key.PressResource.Sony_Ericsson_Java_release_final-20090603)
