Meal Calculator is a meal planner and nutrition calculator for building practical meals around calorie, protein, carb, fat, fiber, sodium, and micronutrient targets.

Create a local profile, choose diet and allergen filters, build meals from the food catalog, and watch nutrient ranges update as you adjust grams. Save meals, plan a day, build a reusable week, add meal prep reminders, and turn saved plans into shopping lists. Log daily calories manually or from meal snapshots, attach local meal photos, track hydration and weight, review history with charts and tables, and export tracker CSV or JSON for personal records. Add custom products with per-100 g nutrition, scan product barcodes in the food catalog, and match unknown barcodes through Open Food Facts before caching the product locally for faster lookup next time. Pro adds body measurements, meal frequency insights, Health Connect nutrition export, Health Connect weight import and step reads, and Open Food Facts product-front image URL lookup. Voice input can add meal builder ingredients through Android speech recognition when the user starts it. Library coaching tips run on device and point out simple next steps from saved meals and plans.

Play mode uses the same nutrition engine for quick food puzzles: build a meal that satisfies the target ranges, earn stars, and keep a streak.
