I am using this application since one year. We can scan our documents easily without using scanner, we can also edit or corp our documents according to our requirement I am the medical student so I need this application in my daily life because when I need notes or any diagram then I simply scan from my phone and we can also scan colour document into black and white after scanning from this app we can do zooming also , when my friends need notes then I simply scan my note book and send notes to my friend in the foam of pdf or we can also send in the foam of image. I get 2 GB cloud space free from this app , I kept all my important documents and and my bank detail in this app. Thia app is safe and secqure after use I log out cam sacn , so no out sider can view my important documents. Really good app.
