How much money is hiding in your home? Take a photo of something you no longer use. ooh. identifies what it is, estimates a rough local resale range, and lets you add it to your hidden-value total. Then scan another thing. And another. The total gets surprisingly addictive. WHAT YOU CAN DO - Snap a photo or choose one from your library - Recognize the product, brand, and model when visible - See a deliberately rough resale range in your local currency - Build a visual collection of the value hiding at home - Mark each saved find as Sell or Keep - Prepare an editable title, price, and description for Facebook Marketplace TEN SCANS ARE FREE Try the complete experience with ten successful scans. If you want to keep going, unlock the whole house with one purchase. No subscription. GOOD TO KNOW ooh. gives rough resale estimates for awareness and entertainment. Values can vary by exact model, condition, location, demand, and selling fees. Estimates are not appraisals, purchase offers, or guaranteed sale prices. Your collection and its photos stay on your device. Photos selected for a scan are sent securely for product recognition and are not stored by ooh. Maybe you do not need more money. Maybe you already have it.
