From Viet Hoang:
The Point Prober App can scan most book's ISBN barcode to find the associated Accelerated Reader (AR) Point Classification, Quiz Number and ATOS Book Level.In addition to standard ISBN lookup, the App leverages an advance matching algorithm that cross references a variety of book sources to locate the correct match. This unique processing allows you to accurately match 96%+ of books you encounter. Even newer and older revisions of existing books who's ISBN are not yet registered with Accelerated Reader's site will lead to correct results.The Point Prober is a no frills, must-have, parent/teacher tool that simply works.
