Apple’s iOS App Store is the world’s most popular on-device mobile app portal by leaps and bounds, but that doesn’t necessarily make it the best opportunity for developers according to Berlin, Germany-based market research firm research2guidance. Apple has a wide lead over competitors in terms of overall downloads and the number of applications in its App Store, but individual apps seemingly have a greater chance of success in rival offerings from Nokia, Microsoft and RIM. ”The ‘average app’ has a better chance to generate downloads on ‘non-hyped’ platforms,” the firm said in a press release on Wednesday. In the second quarter of 2011, the average application in Nokia’s Ovi Store generated 160% more daily downloads than the average iOS app in Apple’s App Store. Individual apps were downloaded from Microsoft’s Windows Marketplace 80% more often each day than from the App Store on average, and apps in RIM’s BlackBerry App World generated 43% more daily downloads than Apple’s offering. Software titles in Google’s Android Market were downloaded 5% less often each day compared to the iOS App Store, and Apple had HP’s webOS App Catalog beat by 95% last quarter.
