Simplifies my life!

Straightforward and easy to use- it’s become my go-to for all kinds of personal and professional situations when I need to make sure I have a copy of any documents. Streamlines things for me, especially for items I don’t necessarily need hard copies, but do want a transaction record. I had no idea how much I would end up using it when I first downloaded it to try!

Best app yet for books

Very simple to use, yet does an excellent job scanning documents, or pages of a book. It does very well correcting for distortions like barrel distortion, angular distortions and page curvature distortions. It also does a very good job eliminating background, text show thru, and gutter shadows. My only wish is for a control to switch between greyscale or color scanning.

Useful for squaring up photos of pictures, too!

It’s made for documents and works well. It handles some tricky distortions. I’ve also started using it on photos, like when I have to take a picture of a painting in a museum from one side to avoid glare. Docr latches onto the edges of the frame and squares it up beautifully!
