WRD Scanner funktioniert nicht

WRD Scanner is a simple-yet-power­ful text re­cog­ni­tion tool that uses state-of-the-art OCR ma­chine learn­ing to scan, high­light, and copy words from phys­ic­al prin­ted documents such as books.  Just point your cam­era at any prin­ted text and enter the keywords or phrase that you'd like to find into the app search bar—those words will quickly become high­lighted on your device screen in real time with great pre­ci­sion.  For ex­ample, say you're at a cafe and the WiFi pass­word is prin­ted on a menu amongst lots of oth­er text—simply take a snap­shot of the menu and draw a box on-screen around the pass­word to quickly and con­veni­ently copy it onto your iPhone or iPad.  All the text in an im­age can be ex­trac­ted with just the tap of a but­ton, and you can even se­lect in­di­vidu­al words and sen­tences to copy.  WRD Scanner can per­form real-time QR code scans too, and is avail­able for both iPhone and iPad.  No account or sign-up is re­quired, and there are no subscriptions or in-app purchases.
