What can you make with the food you already have? Custrd turns a photo of your fridge, pantry, or counter into recipe ideas built around your ingredients. Review what the camera found, see what each recipe uses and what is missing, then follow clear cooking steps when you are ready. SCAN YOUR INGREDIENTS Take a photo, use multiple photos, scan a supported barcode, or try a sample fridge. You stay in control: review and edit the detected ingredients before searching for meals. FIND REAL RECIPES Explore complete recipes with ingredients, instructions, cooking time, and nutrition details. Results show how much of a recipe is already in your Kitchen and what you still need. PERSONALIZE YOUR RESULTS Choose cuisines and dietary preferences, set optional nutrition goals, and use exclusions to shape your results. Always verify recipe ingredients and product labels for your own dietary needs and allergies. KEEP YOUR KITCHEN CURRENT Save ingredients to your Kitchen, track food to use soon, and move missing recipe ingredients to your shopping List. Shared Lists help a household keep the same list up to date. COOK AND KEEP THE RECIPES YOU LOVE Follow step-by-step instructions, save meals, organize your collection, log what you cooked, and share finished dishes. Custrd is free to download. Optional Custrd Pro features are available through in-app purchase. Subscription availability and pricing are shown before purchase. Custrd provides general cooking and nutrition information, not medical advice. Ingredient detection and automated dietary matching can make mistakes. Always check every ingredient yourself before cooking or eating. Privacy Policy: https://custrd.com/privacy Terms of Service: https://custrd.com/terms
