Tapjoy has announced that Tapjoy.com has seen over 4 million registered users. The social advertising and publishing firm also announced that they are rolling out new features, including a better UI, more apps and an improved discovery tool.

“Our goal for Tapjoy.com is to provide a better way for consumers to find, share and engage with great mobile apps,” said Mihir Shah, Tapjoy CEO. “Research shows that consumers struggle with traditional app discovery methods and that they instead prefer to receive personalized recommendations for apps they’re likely to enjoy. The rapid growth of our user base is a testament to the strength of our discovery method. We’ve already helped millions of people find tons of apps that they love, and we look forward to helping millions more.”
