SnapNutrition AI
Free AI calorie tracker for iPhone, iPad, and Apple Watch. Bring your own Anthropic or OpenAI API key for food recognition — no subscription, no ads.
SnapNutrition AI is a free AI-powered calorie tracker and food diary for iOS that uses your own Anthropic or OpenAI API key for food recognition, costing just pennies per scan with no subscription fees. Track calories and macros by snapping a photo, scanning a barcode, typing, or using voice input — with support for Apple Watch, Home Screen widgets, and iCloud sync across devices. The app has no backend servers, stores all data locally on your device, and sends food images directly to your chosen AI provider for analysis. Unlike subscription apps charging $5–15/month, SnapNutrition AI gives you unlimited AI food scanning through your own API key at a fraction of the cost.
