When two speakers want to communicate in different languages, the app provides back-and-forth translation for both speakers (many apps work only in a single direction).
Free CamScanner accounts have access to 200 MB of free storage space. 10 GB storage space is available for full version license (monthly subscription).
The app design makes it very fast to use, with 3 options given when you open the app that will immediately let you start translating, one of them being OCR.
