Clear Scanner: Free PDF Scans is a free app that lets you get a PDF copy of your documents by taking a photo of them just like an office scanner. Running around just to find a scanner is no longer necessary. You can download this app on your phone and get digital copies of notes, papers, contracts, and more with a single press of a button. Organize and edit the files in-app when you scan documents. The business and productivity app can also serve as a back-up with its compatibility with other storage software like Google Drive, Dropbox, Evernote, and more. You can also choose to share the files through other software.
