Mediocre app at a premium price with a twist
The app has all the usual features expected from the scanner app. It’s decent at most (taking photos, batch processing of existing photos) and mediocre at some (auto detection of boundaries, manual processing work flow) tasks. There is a single job at which Abby is excellent: OCR. Most of the competition is using off-the-shelf open source solutions with limited results whereby Abby uses proprietary professional-grade solution for which it has been known for over a decade. In short: unless you really need access to 1st rate OCR on your phone there are many significantly cheaper / free solutions of similar quality available.
