The Pro Stockpile Esquadra Tracker app allows you to turn any room into a digital storage space. Install it if you have things you want to store and want to know where they are. In the app, you can divide a room into several zones or create many small storage areas. For example, if you have a desk with four drawers, you can create four separate storage areas for each drawer and add all your documents to them. You will always know where your stuff is located. The app is suitable for any room, big or small.
