Bisnonna learned the iPhone Duo! - Cook Mode: prop your Duo half open on the counter and the current step moves up top in big type, with a timer dial and flour-proof controls on the bottom half. The screen stays awake while you cook. - Fold it upright and recipes read like a real cookbook: ingredients on the left page, steps on the right. - The whole cookbook now fills the big inner display, with every recipe on the first screen. - Chat with Bisnonna right beside your steps while you cook. - Looks and works beautifully on every iPhone and iPad too. Mangia, mangia.
