Apple really doesn’t let on how it selects the top ten application selections in its App Store, but a developer may have found out just how the method works.

Denys Zhadanov, a member of the development team at Reddie, states that his company has found out just how the company ranks top ten – or higher – apps based on popularity. According to Denys, it takes approximately between 3,500 and 3,800 downloads per day, with a ranking of 4.5 stars or higher, in order to qualify for the Top 10 U.S. Paid iPhone app list. This is based on the company’s experience with the Scanner Pro and Calendars 5 apps, both of which are very popular.

This follows an earlier report from an app research firm named Distimo, which stated that it takes approximately 4,000 downloads per day to make the top 10.

“That’s why it’s important to reach the highest rank possible during the first few days,” stated Zhadanov. “Because it’ll be harder (to climb) later.”

Even more downloads could result in a higher placement, with 7,000 downloads getting the app into a #4 spot for iPhone, or #2 for iPad.
