It's a nice book, of course, though definitely on the thick side. The reason for the app, though, is those times in the grocery store when you want to know "hey, what do I need to buy for this recipe?" Timers would also be very handy. I've used a few of the timers on the iPhone already but this is explicitly set up for cooking.
