Getting featured in App World is one of the best things that can happen to your app. It gives you great exposure and users can find your application without clicking through to categories.
BabyGO! was first seen on BlackBerry Cool and it’s an application like no other. The app locks down the device so you can give it to your child and let them play with it. It has an element of education to it, as the app says the letters that your kid presses, allowing them to absorb the alphabet at a young age.
What would be interesting to measure, is the number of downloads that occur by word-of-mouth. While being featured on App World can result in a surge of downloads from users hitting App World, there is also surely an effect from friends recommending the application once they have tried it. BabyGO! seems like the type of application that would be especially helped by the word-of-mouth factor as parents are constantly sharing advice and parenting tips.
