What's New in VectorShield
1.2
September 29, 2026
This update makes food and menu analysis read the same way on your iPhone and your Apple Watch, and adds dishes whose name is itself the evidence of a trigger. Consistent ratings across iPhone and Apple Watch - The app and the Watch app now share one list of red-meat and dairy triggers instead of three copies that had drifted apart. A meal that rated one way on your phone rated a different way on your wrist; that no longer happens. - Terms the Watch was missing, including sirloin, ribeye, ghee, buttermilk, kefir, ricotta and provolone, are now recognized on the Watch. Dishes recognized by name - Sauces and dishes defined by dairy are now matched: alfredo, queso, tzatziki, hollandaise, bechamel, gratin and au gratin. "Creamed" is matched too. - Dishes defined by mammalian meat are now matched: carbonara (guanciale or pancetta) and stroganoff (beef). Pancetta and guanciale are recognized on their own. How matching works - iPhone matches whole words, so a dish name is read as a dish name. "Cream" no longer fails to match "creamed". - Terms that name an ingredient without proving one are still left out on purpose. "Ranch" and "aioli" are not treated as dairy, because the name is not the evidence.
