It seems right that a cutting-edge design and architectural movement of the past has its own smartphone presence, as is the case with the Bauhaus Archive iPhone app.
According to Dexigner, this is an official app for both iPhone and iPod touch that opens up the Bauhaus archive via the exhibition The Bauhaus Collection: Originals of Classic Modernism. Over 100 images, along with commentary in English or German, some context as to what the Bauhaus movement achieved and some visitor information, should you fancy seeing the real thing in Berlin.
Best of all, it's a free download. Always a good thing.
