What is Offline?

Offline access means you can download lessons or books in advance and study them with no internet connection, which matters on a commute or with an unstable line. Language apps and reading platforms most often build it in. ABA English, AfriKDP, Audible and Audiobooks.com all state that their apps work offline. Baibu does not, so its material needs a live connection. Look for a download option in the app before you pay for a subscription you expect to use on a plane or abroad, since offline access is rarely mentioned in the headline price.
