MacroCart: Scan & Plan

MacroCart turns the grocery aisle into a five-second decision. Scan any barcode and get one clear verdict — Great Fit, Good, Okay, Be Careful, or Skip — scored to your personal goal, before it ever reaches your cart.

No food diary. No calorie math. No logging every meal after you've eaten it. Just a straight answer while you're still holding the product.

• Scan a barcode (or snap the Nutrition Facts label) and get an instant 0–100 score and verdict. 
• Every product is scored against YOUR goal — lose weight, build muscle, high protein, low carb, watch sugar or sodium, and more. 
• Tap "Why this score" to see exactly what added or removed points.
  
DIET & ALLERGEN GUARD
• Set your allergens and diet style once (vegan, vegetarian, pescatarian, keto, gluten-free, halal, and more).
• Anything that clashes is flagged first — so a product that breaks your diet can never read as a good pick. 
  
BUILT FOR REAL SHOPPING
• Cart: see how a whole basket fits your day.
• Pantry: track what you've bought and your macros on hand.
• History & compare: revisit past scans and pick the better option.
  
PRIVATE BY DESIGN
• No account. No sign-up.
• Your scans, pantry, and goals stay on your phone — nothing is sold or shared.
  
SMART ON-DEVICE AI (optional)
On iPhone 15 Pro, the iPhone 16 family, or later (iOS 26+), MacroCart uses Apple Intelligence on-device for richer explanations, smart swaps, meal ideas, and Snap-a-label — and nothing is sent to a server. On other iPhones the core verdict, scoring, and diet/allergen guard work exactly the same.
