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:

  • to be free
  • to save in color
  • to auto-optimize
  • to allow me to crop it
  • export to image and PDF
  • auto/manual 'perspective' (?) fix

By perspective, I mean it should look straight even if I took it at a slight angle.

I don't care if it is:

  • ad-supported, or
  • flooded with in-app purchases

as long the above features are in the free version.

Evernote Scannable

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.

  • Great app! +1. I like how you can pay to have OCR features, but @grgargside answered first, and it is unlikely I'll be paying in the future :) – ᔕᖺᘎᕊ Feb 2 '15 at 9:44
  • @ᔕᖺᘎᕊ the most important reason why not to pay for OCR is that they're still quite unreliable and never produce good enough results. (: – user111 Feb 2 '15 at 16:24

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.
