An app where you log all your stuff you have and it does a search in various classifieds for the best price

You add your stuff you have, the app has a database of known prices of the stuff, and periodically checks in classifieds like Craigslist, Facebook Marketplace, and others if there are higher bids than the current price in the database.<br><br>You can add your stuff manually by taking a picture or scanning the barcode, or you can synchronize it with photos you have on your phone and google photos. You can also synchronize it with receipts. <br><br>When it finds a better bid, it will send you a notification and you can sell it and update the price in the app.
