If it serves any purpose just today I've published docscandroid.app just because the document scanners out there are really scary and do not really fit my purpose. My app is not perfect but its mine and that is enough.

The parent poster decries fake and scammy apps, and you post a link to an app that contains absolutely zero information on who controls it, how my data is used, where my data is stored, etc.

If you built your own app that does exactly what you want for your own use, kudos and more power to you. But otherwise...

You're competing with Google. The built-in Drive app does document scanning.
