The short answer is yes! Not only should they make them for Symbian, according to the latest numbers it is the best OS for them to develop for.
The graph above shows that if you make a Symbian app, your app will be download on average 160% more than if you would make one for iOS. Now this is not a jumping off point to make grand claims of Nokia’s app store being the best. These facts just show that it is the best for developers.
It it really a big fish in a small pond deal…App store for Apple has the biggest amount of apps by far, and with that many to choose from it’s hard for your app to stand out. Since OVI store is smaller but still gets 9 million downloads a day, it is the perfect mix of consumer and competition for the developer.
So developers take note, if you make Symbian apps your app will have the best chance of succeeding.
