MacroSight

Health & Fitness

Free

Track every macro, vitamin, and mineral across iPhone, iPad, Mac, and Apple Watch. KEY FEATURES • Three ways to log: AI photo estimate, on-device label scanner, or a 1M+ food catalog (USDA + Open Food Facts). • Barcode scanning for packaged foods. • 30+ tracked nutrients: macros, vitamins, minerals, omegas, controversial ingredients. • Apple Intelligence: when enabled, AI estimation runs entirely on-device — no API key, no network round-trip. • Bring your own API key: paste an Anthropic Claude key for cloud AI photo estimation. • Apple Health integration: reads body composition, writes nutrition. • iCloud sync: every entry, goal, and template across all your devices. • Home/Lock-screen widgets and Apple Watch app. Integrates with Apple Health: writes your nutrition (energy, protein, carbs, fat, fiber, sugar, sodium, vitamins, minerals) and reads body composition (weight, BMI, body fat, lean mass) so your daily targets stay personalised. HealthKit is opt-in; you choose which categories to share. PRIVACY MacroSight stores your data in your private iCloud database — we have no servers that see it. Photos sent to Claude or other AI providers are never used for training. The food catalog is fetched anonymously through a Vercel proxy. Food data: USDA FoodData Central (public domain) + Open Food Facts (ODbL).

Version 1.4 — log faster, with smarter targets • Describe your meal — type or dictate what you ate (or snap one photo of your plate) and we split it into separate items you can adjust and log together. • Targets that learn — adaptive goals estimate your real calorie burn from your logging and weight trend, then keep your targets dialed in. • Scan a menu — photograph a restaurant menu for quick dish estimates, ready to log. • Weekly report & consistency — a plain-English AI recap of your week, a logging heatmap, and weekly habit goals. • Plan your day — see what fits your remaining macros and pre-plan tomorrow. • Fasting tracker — set an eating window and watch a live fasting timer. • Coach-ready PDF — export a 30-day report to share with a trainer or clinician. Also: fixed a bug where some barcoded items (like canned drinks) showed calories per 100 ml instead of per serving. Thanks for using MacroSight!
