Stack

Stack is an app developed by Google for scanning your documents quickly and efficiently. Thanks to its minimalist interface, it only takes a few seconds to capture each image and save it privately. In fact, the app even automatically organizes all the files you scan.

With Stack, you can scan any document and keep all your invoices, receipts, and notes in one place. To do so, take a snapshot of each file with your smartphone's camera or upload any file saved on your smartphone's gallery.

One of the advantages of using Stack is that the app automatically organizes all your documents. Thanks to an intelligent renaming system, all your files will be automatically sorted into folders, although you can also manually add labels or names whenever you see fit.

Stack has everything you need to scan PDF files and sort them into organized folders as efficiently as possible. This app also operates under a privacy criterion that ensures all your information remains protected from third parties. Even better, there are no ads, and it all comes with a stamp of approval from one of the most powerful internally-run Google incubators.
