From the Store description, in slightly 'pidgen' English - it's not clear where 'Define Studio' is based, but don't judge the quality of OCR in the app by the quality of their own written English(!)

My guess is that they're using a third party OCR engine of some kind - the range of languages supported is so vast that it surely has to be part of a big project - there are several candidates, though none mentioned in the application itself. It's impossible to conceive that a v1.0 OCR application like this could otherwise work as faultlessly as it does.
Having said that, credit to the developers for packaging the online functionality so compactly and smoothly - Photo Scan is a free application monetised through banner ads, which can be removed for a one off £1.50 IAP, which is fair enough.
Here's Photo Scan in action:
Well worth a look if this is something you need to do. And worth noting that it's a full UWP app and works just as well on a tablet or laptop - camera permitting, arguably the high spec phone camera makes all the difference here (I was using a Lumia 950).
