Free OCR iPhone Apps

iOS & iPadOS
Hi there! I'm very glad to visit applevis and use most of the fantastic apps for my Iphone 5 by VO. I wonder something. Would you like to tell me a list of accessibility ocr scan apps for iphone/VO? I want to read example a document, letter etc then I will take a Photo with iPhone to reading aloud. The only app for free I know is Saytext, but I don't think it's work well. I alos heard about Prizmo but the apps costs little bit. What of scan ocr apps would you recommending me?!! Thank you
