Very poor for meat
First of all, the app does recognize only steak (no other parts of cow) and only four to five possible pork cuts. For steak, the maximum thickness is 5cm even though most of the premium steak cuts are thicker. The worst thing is, however, that the temperatures for steak are completely wrong (recommending internal temperature between 50-55C for RAW steak - before resting). Follo these instructions and you will surely overcook you meat.
