Sadly, the best there is.

I havent played bridge in 40 years while in college and I wasnt that good then. But about 50% of the times Ive compared my performance on rubber games to the automatic play, I do better. The bidding also seems a bit weird at times as well. And Im not a fan of the busy interface.

That said, it appears to be the only serviceable app for bridge in the iTunes Store. Also, the developer is quite responsive and that counts for something.
