Don't bother
Not a scanner at all, still just takes a photo with your camera and you have to edit. Ones you when you search free scanner also, but it's not. It costs $8.99 per week!
Response from developer
Sorry for the not metting your expectactations. Yes, all scanners of this kind work using a camera. In our app you can find "Edit" function, which can achieve almost the same document as on a laser scanners. If you don't want to use a subscription, you can also use the free features of the app.
