Calfo is an iPhone app that helps households keep track of food, plan meals, and spend less on groceries. Designed for people who regularly shop and cook, it makes pantry management easier without requiring users to enter every item manually. Add groceries by photographing shelves, scanning barcodes or receipts, or speaking what you bought. Calfo organizes the inventory, tracks estimated expiration dates, and can send alerts before food goes bad.

The app suggests recipes based on ingredients already at home, prioritizing items nearing expiry, and creates grocery lists from what is missing. Users can also plan meals for the week, set calorie and macronutrient goals, and add dietary preferences or allergies to guide recipe suggestions. Calfo Pro offers features including photo-based pantry entry, voice logging, automatic weekly meal-plan filling, and shared household access to a pantry, grocery list, and meal plan. Members retain individual nutrition goals. Calfo is free to download, with a free plan that includes scanning, expiration tracking, meal planning, and eight recipe searches per day; Calfo Pro costs $5.99 per month.
