"Now that Apple no longer supports heightened visibility after updates, we did not really see an increase in sales when we updated Guess the News," said audience member Isabella Saller, head of marketing for Finger Arts, an independent iPhone game developer in Silicon Valley. "So far, frequent updates have not translated into more sales for us."

Because of this, developers are realizing that it's not enough to keep the game fresh for users; it's also necessary to communicate directly with customers, to let them know the game still exists and it's still exciting.

Pusenjak stresses the importance of using the description box to the fullest when posting a new update. Instead of just detailing what's in the update, he explained, a developer should also take some time to address gamers directly, by thanking them for their support and urging them to send emails with their comments and suggestions. At the same time, an update is also a great chance to plug other games.

After frequent updates, the Internet is a developer's greatest tool. A Web site with an up-to-date blog and feedback forums can do a lot to turn a game into a community. Social networks are also key, because they allow gamers to form a relationship with developers.
