Perfect OCR scans your documents using advanced image-processing algorithms to eliminate uneven lighting and shadows and improve contrast. The result is the clearest and most readable scans possible from the iPhone's camera. Perfect OCR also offers SureScan, our proprietary scanning mode that delivers sharper images with less jitter or smear.

Our unique "Email to myself" feature lets you send documents to a predefined address, or even upload them to an online storage service like Evernote or, with a single tap. Uploading documents to online services via email is fast, secure, and can be done even if you're temporarily off line. Refer to app help for details.

All processing happens on your iPhone, and the confidentiality of your data is never compromised. There is also no subscription fee, and no Internet access is needed to scan documents or run OCR.

Customer Reviews

Pretty good, but note the limitations

I was trying to scan some old bulletins (typewritten, so pretty standard font). What I wanted was a searchable PDF file of the bulletin.

This product will not help me with that.

The OCR was OK. If the text was prose, then it did a good job. It fell down when the type was not perfectly clear, and when ALL CAPS were used (which the editor used often for people's names).

Also the bulletins tended to have little pictures spread across the page. That tripped it up, and they were converted to random gibberish characters.

My rating would have been higher, and I would find the app useful if it could mail the entire PDF when I was done, with the error-filled text, so that I could correct it offline. The description says it, but I'll be clear -- when you send a "image" PDF, your only option is to send an image of the last page. Nothing else. Not the first, nor all, just the last.

If you send the _text_ as PDF, it can be multi-page, but I didn't catch that subtlety before purchasing.

Great app

I'd give it 4.5 if I could. It works very well on standard print, and I've even managed to scan and convert to text from Kindle for Windows 8. This has gotten out of tight spots when researching, writing and presenting. Smaller text, yellowed paper, and any fancier text produce poorer results. It is quite fast for OCR, and I rarely take more than one pic per scan. If I see one fault, it is the line breaks it puts in that don't seem to match what is on the page. That makes for some tedious editing.

Perfect OCR 2.4.1 needs to be updated ASAP!

Perfect OCR 2.4.1 needs to be updated ASAP!

It is not a 32 bit app and will not work on iPhone after the next version of iOS is released (probably next month, August, 2017).

I love Perfect OCR, and would gladly pay for an upgraded version!
