Yes! FoodGrader caches your recent scans and favorite products for offline access. You can view previously scanned items and their scores without an internet connection. New scans require internet to fetch product data.

When you create a profile, you describe your dietary needs in plain English (e.g., "I'm diabetic and trying to lose weight"). Our AI understands your requirements and creates a scoring algorithm specifically for you. Every product is then evaluated against YOUR needs, not generic standards.

Vision scanning is the official fallback. If a barcode is damaged or missing, just snap the nutrition label. FoodGrader parses every ingredient, applies your allergen + FODMAP rules, and stores the scan so you can revisit it later.

Yes. Toggle the FODMAP profile switch and FoodGrader will highlight fermentable carbs across scans, history, and favorites. You can combine it with any other goals (weight loss, diabetes-friendly, etc.) and even mention IBS triggers in plain English during onboarding.
