Apple reported on Thursday that over 3,500 iPad-native apps are already available, and that over 4 billion apps have been downloaded for the iPhone, iPod touch and iPad so far.
The company also said that over 185,000 apps are currently available for download in the iTunes-based App Store. Along with iPad apps, the multimedia tablet device can run most iPhone apps, too.
Apple introduced the iPad on April 3, but developers were able to work on their iPad-native apps ahead of the launch thanks to the early release of an iPad-compatible iPhone OS software developer kit. With the iPad in developers hands now, the number of native apps should continue to climb.
