Katta?
Lifestyle
Free · Designed for iPad. Not verified for macOS.
Swipe items between “To Buy” and “In Stock.” Avoid forgotten or duplicate purchases, and share your list with family via iCloud.
Katta? is a simple inventory-checking app designed to help you avoid those everyday questions: “What was I supposed to buy?” and “Did I already buy this?”
Organize household essentials into two simple lists: “To Buy” and “In Stock.” When you buy something, just swipe it to “In Stock.” When you run out, swipe it back to “To Buy.” There’s no need to keep track of exact quantities—you can quickly see what you need the next time you go shopping.
Key Features:
• Organize items into “To Buy” and “In Stock” lists
• Easily move items between lists with a swipe
• Add notes and photos to individual items
• See estimates of how quickly you use each item
• Share lists with others via iCloud
Want to use the same list with your family or housemates? iCloud sharing makes it easy to keep everyone on the same page.
Katta? keeps everyday shopping and inventory checking simple, quick, and hassle-free.
