GrillTime
Read full descriptionHide full description
GrillTime is not a generic countdown timer. It is a cooking engine for the grill that builds a precise timer for every cut from the things that actually matter: the cut of meat, its thickness, your heat level, and the doneness you want. Pick a cut, set the thickness with a stepper, choose Low, Medium or High heat, and slide the color doneness bar from rare to well-done. GrillTime instantly calculates the total cook time and the exact minute to flip, and shows the internal temperature you are aiming for. While you cook, the timer splits the job into clear phases: sear side A, flip now, sear side B, then rest. Alerts fire with haptics and local notifications that reach you even when your phone is locked, so you never miss the flip. The full-screen timer keeps the screen awake with a giant, easy-to-read countdown. Cooking a whole spread at once? The Cook Board runs several cuts side by side on one grill. Set a Serve At time and GrillTime staggers each cut's start backwards so the steak, the burgers and the chicken all finish together, right on time. GrillTime also keeps a built-in reference of safe internal temperatures for beef, pork, chicken, fish and ground meat, plus a doneness guide, so you can cook with confidence.
