About this app

This little application provides a way on scanning handwritten notes and printed documents.

It automatically detect the edge of the paper over a contrastant surface.

If you have RocketBook Wave notebook or home printed pages it automatically detects the qrcode printed on the bottom right corner and scans the page immediately.

After the page is detected, it compensates any perspective from the image adjusting it to a 90 degree top view and saves it on a folder on the device.

It is also possible to launch the application from any other application that asks for a picture, just make sure that there is no default application associated with this action.

Can be also installed from F-Droid:

I've been using this app since its day on F-Droid, and there are some pros and cons with this newer version. It seems to have improved it's "document detection" ability - it's able to pick up (for me) a page on a lower contrast background than it could previously. That's good as I'm having to scan documents on a light background much of the time. On the other hand, the image processor seems to have lost a little bit in this iteration. Documents that used to be crisp are now unreadable with the image processor enabled, and many times I have to scan a document with the processor disabled. All in all it's still a useful tool and you can't beat the "no ads" and simple interface, but I'd like to see the image processing brought back to the level it was in prior versions.

I know that I can disable usage data in the settings, but what is being transmitted if I enable it? UPDATE: In my use the app was unable to detect the page, so needed to grab everything visible, and then would not show the image in the app's gallery, so I wasn't able to see how it did. I have since uninstalled, so the answer to the usage data will not be relevant to me, but possibly someone else.

It is definitely a bad option if you have to install a scanner app. I thought it will work great because it is open source but it works like a camera. Another problem is the image size: the same as a regular shot. My conclusion is that it doesn't worth the purpose. I will still searching for a great open source scanner app.

The reason I started it is because there was no open source scanner. Some improvements are on the way and the project is open to accept feature contributions!
