(For best results, I recommend using lots of light on documents you’re scanning, and using invert and 3D deskew before converting.) Although no app does the job of OCR perfectly, this one gets close enough for further editing, so saving lots of time transcribing docs manually via typing, PLUS it’s free (did I mention that it’s free?) ### 1/5 — Was 3/4 stars *2020-10-07, version 6.1.2* Non unusable after its update or ios 14. Normally one option for grabbing a photo is Screenshots. Gone. Another was Recents. Gone. Worse: I can’t get text! Before, after extraction, I could select a section of text to copy. Now when I hold done my finger I get a Share option only. But selecting that 1) requires sending it and 2) puts a copy of the IMAGE, not text in the doc. Useless. The functionality is completely gone. ### 3/5 — Don’t Know *2020-10-04, version 6.1.2* I used “”StitchPics” which sticker screenshots i took, the screenshots were of a digital document sample so the image Is legible and pretty clear, this app cannot pick up on the text present which got my hopes down. Oh well!! Guess I am typing everything from scratch ### 5/5 — Finally a good one *2020-08-09, version 6.1.1* This is the first image to text app that is ACTUALLY free AND works. 👍 ### 5/5 — Fantastic! A MUST-have App *2020-06-06, version 6.1.1* The OCR Scanner is very fast and accurate. And did I mentioned it works for multiple languages. The OCR Scanner app gives you a simple and efficient way to capture that interesting poem, quote, or small article you come across without having to painstakingly write it down by hand. You can Camera Scan existing pages or import from the Photo Library. The app will extract the text from a picture and convert it to an editable text file. You can copy and paste the extracted text to an iMessage, Notes, email or word processing app and make edits/corrections or reformatting as necessary. It also Has a Tables option to scan tables. Download it now! :-) ### 5/5 — Finally!! *2020-05-26, version 6.1.1* I’ve been looking for an app to do exactly what this app does perfectly, recognize images with text and convert them to pdf, also PDFs that are images and recognize the text. Thank you! ### 4/5 — Love it but needs minor fixes *2020-05-25, version 6.1.1* I really love the app, but when scanning recipes for some reason it omits tsp and TBS every single time. Have to manually add them back in. Also it changes numbers like 60 to 6o (has an o instead of a zero) again, I have to fix this manually. Would be nice if it could recognize numbers that have zeros. Otherwise it works great! ### 1/5 — Can't select another language *2020-05-13, version 6.1.1* I went to use this OCR in Russian, but it does not work, even when downloaded the Russian language. I press it but it does nothing. Please fix. ### 5/5 — Very competent OCR for free. *2020-04-27, version 6.1.1* A service to the ‘rest of us’. ## Frequently asked questions about OCR Scanner with LEADTOOLS SDK ### What does the OCR Scanner app do?
