It's easy to tote your smartphone in the kitchen, and utilize the app, which contains all of the recipes you find in the Everyday Food  magazine. Plus, the app is updated monthly with new concoctions found in the physical mag, so you never get bored and the app won't go stale! Get it? Stale? Yeah, I thought that was pretty funny.
