As a college student I often need to scan documents, paper, reports, and an abundance of other things to send to other students as well as teachers. One problem with this is that my printers scanner is horrible and inconvenient. I found this app after a free app group called AppGratis advertised the free version (which is phenomenal), and I bought this version when that group dropped the price to $1.99. This app is absolutely worth the money and I HIGHLY recommend it for individuals who frequently need to scan things. This is hands down the most efficient way to do it.
