Oh, yes. Many. But I suspect you're looking for something in a similar price range ....

LithUnwrap, a freeware UV-mapping utility by Brad Bolthouse

Ultimate Unwrap3D, the commercial version of LithUnwrap ($34.99)

Both utilities are PC-only. The commercial version has a downloadable demo, although all of its save functions are disabled. Try LithUnwrap first to get a better idea of its functionality. It's no longer supported or updated by the author, but he doesn't mind it still being available, as most of us who've used it upgrade to the newer commercial version eventually.
