DietaryLog
Snap meals. AI calories.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
DietaryLog is a photo-first food diary. Snap a photo to log each meal, let AI estimate calories and macros, and get advice from a built-in AI nutritionist that factors in your recent health trend.
Features • Photo logging: camera or library, with an automatic timestamp watermark • AI calorie estimate: one tap to estimate calories and protein / carbs / fat • AI nutritionist: combines your last 7 days from Apple Health (weight, body fat, active energy, steps, workouts, sleep) for trend-aware advice; the AI runs on-device • Body composition: weight / body-fat trend charts • Streaks & levels to help build the habit • Light / dark themes, backup & restore • Privacy-first: your diary stays on your device and only leaves when you choose to share; Health data is read-only, never written
Multi-language Traditional Chinese and English — follows your system language or switch manually.
