🥗 Foodiary

Your meals, your target, your day — planned simply.

Foodiary is a local-first iOS calorie tracker and daily meal planner. Set a personal calorie target, plan meals from breakfast to dinner, and track whether you're under, near, or over your estimated daily target. No accounts, no cloud, no complexity.

✨ Features

• Personal calorie profile — age, sex, height, weight, activity level, goal
• Mifflin-St Jeor BMR calculation with activity multipliers and goal adjustments
• Daily meal planning — 4 fixed slots: Breakfast, Lunch, Snack, Dinner
• Food search — query FatSecret and USDA databases for nutritional info
• Manual food entry — add name, calories, and optional notes
• Live calorie tracking — planned vs remaining with progress visualization

• Weekly plan view — browse past and future meal plans
• Insights — calorie trends and observations
• Dark mode — full dynamic theming with Light / Dark / System toggle
• Bilingual — Indonesian (default) and English with live language switching
• Neutral language — never shames. "120 kcal over your estimated target", not "you failed"
• Local-first — all data stored on device via SwiftData. No account, no internet required
• Edit & recalculate — full onboarding-style profile edit flow, target updates automatically
