I am looking for a free app that allows me to take pictures of documents ('scans'), and the app optimizes it.
I would like it:
By perspective, I mean it should look straight even if I took it at a slight angle.
I don't care if it is:
as long the above features are in the free version.
Evernote Scannable is a free iOS app that scans documents, fixing perspective and enhancing the result. It is very quick to scan documents and can be set up to automatically scan documents that it detects are placed in front of the camera.
Scanbot should fit your needs just fine.
The basic free version can capture documents with automatic cropping and perspective correction, the premium version adds OCR and cloud export capabilities.
(screenshot of a lottery ticket scanned automatically, I didn't even need to press the trigger as the app automatically captures the document when light and focus are good enough)
I'm using Scanner Mini from Readdle and I'm really happy with it:

It even offers OCR, and it'S really stable for a free app.
