REPLAiTE - Smarter cooking. Less waste. Powered by AI.

App Overview

The app is called REPLAiTE and is available on mobile devices running iOS. It is designed for everyday individuals and families who want to reduce food waste, save money, and cook more efficiently by using the ingredients they already have at home.

Core Purpose

REPLAiTE is a sustainability-focused mobile app that leverages AI to scan your fridge and pantry, identify ingredients, and suggest quick, efficient, and personalized recipes. It empowers users to waste less, cook smartly, and live more sustainably—all while catering to dietary needs such as vegetarian, vegan, lactose-free, and more. It also tracks the impact of food saved and money preserved.

Key Features

The AI Ingredient Scanner uses your phone’s camera to scan the inside of your fridge or pantry, automatically detecting ingredients with ease. Smart Recipe Suggestions are instantly generated based on the identified ingredients, your dietary preferences, and the amount of time you have available. The app supports a wide range of Dietary Preferences, offering filters for vegetarian, gluten-free, vegan, and allergen-aware cooking. To promote sustainability, Waste Reduction Tracking monitors your food-saving impact, measuring both the kilograms of waste prevented and the dollars saved. Weekly Goals & Achievements encourage consistent engagement by motivating users to stay aligned with their sustainability objectives. With a Quick-Access Design, all major features—including Scan, Recipes, Track, and Personalize—are just two taps away.

App Pages

1. Home Page The Home Page features an Expiring Soon list that highlights ingredients in your fridge or pantry that are nearing expiration, helping you prioritize their use. A Daily Food Waste Tip is displayed to encourage smarter food habits and raise awareness. At the center of the interface are Quick Action Buttons—“Scan Fridge” and “Find Recipes”—allowing users to take immediate action with just a tap. Based on your scanned ingredients or current trends, the app also showcases Recommended Recipe Previews, giving users inspiration tailored to what they already have at home.

2. Scan Page The app requests camera access to enable real-time scanning of your fridge or pantry. Using advanced AI, it performs live ingredient detection, recognizing and identifying items as you scan. Once the scan is complete, an Identified Ingredient List is displayed on-screen for review. A prominent “Generate Recipes” button allows users to instantly move from ingredient detection to viewing personalized, matched recipe suggestions.

The app uses a 2-Stage AI System: LogMeal AI powers the ingredient detection by analyzing images from the user’s camera, while Gemini AI takes the identified ingredients and generates personalized recipes tailored to dietary preferences, cook time, and sustainability goals.

3. Recipe Page The Recipe Page displays a list of recipe results generated from either the AI ingredient scan or manual user-selected filters. A Filter Bar at the top allows users to refine results based on Cook Time (e.g., under 15 minutes, under 30 minutes), Diet Type (such as vegetarian or lactose-free), and Tags like Quick, Easy, Low Waste, or Leftovers. Selecting a recipe opens the Recipe Detail View, which includes step-by-step instructions, ingredient substitution tips, and a Save button that lets users add the recipe to their personal Saved Recipes collection for future access.

4. Tracker Page The Tracker Page provides users with a comprehensive view of their sustainability progress. It displays the total amount of food saved, measured in kilograms, and the money saved, calculated in dollars. A weekly goal progress bar helps users stay on track by visualizing their advancement toward food waste reduction targets. To celebrate milestones, users earn achievements—badges like “Zero-Waste Hero” or “Clean Plate Club.” The page also includes monthly sustainability statistics, offering a broader perspective on long-term impact and behavioral trends.

5. User Profile Page The User Profile page features the user’s avatar and name at the top for a personalized experience. Users can update their dietary preferences, ensuring that all recipe suggestions align with their needs and restrictions. A Saved Recipes Library allows quick access to previously saved meals. From this page, users can also manage notification settings and adjust general app settings to customize their experience. A Logout button is included at the bottom for easy sign-out.
