After a false start late Monday, Skype has officially landed on the iPad.

The popular web-based calling service announced Tuesday that an app optimized for Apple's tablet computers is now available.

Before, users could use the Skype iPhone app, which has been available since New Year's Eve 2010, on the iPad, but it wasn't optimized for the tablet's screen size and features.

"The large iPad screen is perfect for bringing Skype video calls to life, in either landscape or portrait view, and because it is on the iPad, Skype video calls can be made at the beach, in a car or even lying on a couch," Rick Osterloh, Skype's head of consumer product management, said in a blog post Tuesday.

The app allows audio calls on the original iPad and video calls on the iPad 2, which has two cameras. iPad 2 users can conduct two-way video calls with other iPads and users of the iPhone app, phones with Skype for Android or Skype for Windows, and other devices with front-facing cameras. (Skype for Android, with video calling, was rolled out last month).
