This Android App (Microsoft Lens) is currently in beta but is one of the best document scanners out there. What impresses me is the accuracy of the scans (corner detection) and the clarity of the result. If you are in the world of Microsoft and use OneNote and OneDrive, this is a must-have app. When you complete a scan you are given the option to upload the scan (PDF or Image option) to OneNote, OneDrive or both. You can also convert the scan of a document to Microsoft Word or Powerpoint using OCR technology (Optical Character Recognition). Since this is in beta, you may have to sign up as a beta tester to download the app.
Scan and upload all your notes, receipts, and documents. Increase your productivity by eliminating time spent looking for documents or business cards. Sketch your ideas and snap a picture for later. Whether you’re using it for business or education, Office Lens will help you save and share your documents in OneNote and OneDrive so you can all work together.
