"WT, English Wikipedia Offline 2" is the second part of the English Wikipedia Offline (the full version) App which has many parts: the first part is the main program providing core functions such as offline/online article searching and viewing, and this "App" acts as an extension of the main program serving a major part of all offline articles.
Please note this part relies on the first part of the English Wikipedia Offline App which is free.
Thank you.
