✨ Key Features

• Dual AI Providers — OpenAI & Google Gemini. Switch providers and models instantly via Firebase Remote Config — no app update needed.
• AI Recipe Generator — Enter pantry ingredients and get complete, realistic recipes with full nutrition data, chef tips, and ingredient substitutions.
• 7-Day AI Meal Planner — Auto-generate a full weekly meal plan balanced to your calorie goal, dietary preference, and cuisine variety rules.
• Smart Shopping List — Turn your weekly meal plan into a grocery list in one tap. Duplicate ingredients are merged across recipes with quantities added up, everything is grouped by supermarket aisle, and tick-off progress syncs and survives plan changes.

• ‍ Step-by-Step Cooking Mode — Full-screen immersive view, wakelock (screen stays on), auto countdown timers, voice navigation, and an ingredients side panel.
• Serving Adjuster — Scale any recipe from 1 to 12+ servings. All ingredient quantities recalculate automatically with fraction formatting.
• Ingredient Substitutions — AI-powered substitution suggestions that respect your dietary preferences and allergies.
