Microsoft lens has to be my absolute favorite app. It basically scans and interprets all kinds of documents. Office Lens can turn pieces of paper into workable documents or PDFs. So you can scan a form or document on your phone, send it to your laptop to work on it or work on it straight from your iPhone! (College tip, it can even understand powerpoint slides on a projector for when a professor overloads the slides)

The biggest downside of the app is when the page you are trying to upload contains images. The app tries to interpret them, but it usually ends up being scrambled letters. But other than that, HOW COOL? I love technology!
