BBQ Handbook is an all-in-one grill and BBQ helper app that gives you the guidelines for cooking times, internal temperatures for various cuts of meat, direct or indirect cooking and much more.
Please note that these "guidelines" are just that, and your results may vary depending upon a number of factors, including: weight, shape/thickness, and internal temperature of the meat; amount of meat cooked; weather conditions; type and amount of fuel used; cooker temperature; and how many times you open the cooker or grill during the cooking process.
