Michael Ruhlman's 'Ratio' iPhone App Now Available

20091216-ruhlmaniphone-newer.jpgThe iPhone app based on author Michael Ruhlman's book Ratio is now available in the Apple App Store. I've downloaded it and messed around with it. It's a pretty handsome and very well thought-out lil' app. I think I'm going to put it to the test tonight in preparing cookies for our office cookie swap tomorrow.
