About VectorShield
Alpha-Gal Syndrome reactions are delayed, invisible, and hard to trace. They start 3-6 hours after eating -- long after you've forgotten what was on your plate. VectorShield is a safety reference database for people with Alpha-Gal Syndrome: search medications, browse restaurants, and keep a personal log of meals and vitals in one place. MEDICATION SAFETY DATABASE Many common medications contain mammalian-derived inactive ingredients -- gelatin capsules, magnesium stearate, bovine-sourced collagen -- that do not appear on the label. VectorShield checks a curated database of medication ingredients to flag possible Alpha-Gal triggers so you can review them before you take them. Emergency medication lookups (EpiPen, epinephrine) are always free. RESTAURANT SAFETY DATABASE Browse 377+ restaurants and 8,400+ menu items with Alpha-Gal safety ratings. See cooking fat disclosures, cross-contamination notes, and community-sourced reviews from other AGS patients. Find safe dining options near you on an interactive map. MEAL LOGGING AND VITALS TRACKING Log meals by voice, text, photo, or barcode scan. VectorShield reads your heart rate and HRV from Apple Watch and displays trends alongside your meal log -- giving you a personal reference record to review at your own pace. All processing runs on-device via CoreML; your Apple Watch vitals are never sent to our servers and never sold. COMMUNITY Connect with other Alpha-Gal patients. Share restaurant reviews, post safe recipes, follow other members, and learn from people who understand what you're dealing with. BUILT FOR EVERY SENSITIVITY LEVEL Alpha-Gal Syndrome is not one-size-fits-all. Some patients only avoid red meat. Others react to dairy, gelatin, or even trace amounts in medications. VectorShield lets you set your sensitivity level (1-4) so food analysis, medication warnings, and personal context are calibrated to your specific situation. APPLE WATCH COMPANION The Watch app runs independently with voice-first meal logging, vitals tracking, restaurant search, and on-wrist notifications. Log a meal by speaking to your watch without pulling out your phone. PRIVACY FIRST Your Apple Watch health data is processed on-device using CoreML and is never sent to our servers or sold. VectorShield does not track you and does not require an account for core safety features. FREE FEATURES - Meal logging with voice, photo, and barcode input - 5 medication safety searches per day - Vitals tracking via Apple Watch - Community access - Emergency medication lookup (always free) PREMIUM ($2.99/month) - Unlimited medication and food database searches - Personal sensitivity calibration and extended history - 365 days of history and trend analysis - Offline database access - Data export for healthcare providers VectorShield is a safety reference tool, not a medical device. It is not intended to diagnose, treat, cure, or prevent any medical condition. All tracking and personal records are for informational and reference purposes only. Consult your healthcare provider for medical decisions. In an emergency, call 911.
What’s new
Version 1.2 · Updated 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.
