Any weekend warrior can waddle to the supermarket, grab a steak, and slap it on a grill. But if you want your moniker among the elites in this BBQ-crazy nation, you need to really know your meat. Pat LaFrieda’s Big App for Meat ($6.99) has all the information you need about more than 200 cuts of beef, lamb, pork, veal, chicken, turkey and duck. You get tons of glorious pictures of meat, plus more than 50 minutes of video showing you professional butcher techniques. Will passersby be alarmed when they see you checking out the 360-degree rotating meat cuts on your mobile device? Yeah, probably. But they’ll never know the true beauty of a skirt steak viewed at a 57-degree angle, will they?
