Aristocrat 1.1 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The most popular version of the tool is 1.0. This free Mac application was originally created by Josh Parnham. Aristocrat works fine with Mac OS X 10.8 or later. The application lies within Productivity Tools, more precisely Office Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
Aristocrat is simple utility that allows you to decode barcodes on your screen and read the text in images and scanned PDFs.
After choosing "Capture Screen..." in the Aristocrat menu bar, select an area of your screen (which can be done through a system-wide hotkey) and Aristocrat works its magic.
