one small addition from my side: Technically speaking, the offline database is indeed also available on iOS, not only on Android. However, different from Android, you can’t run a business application fully offline on iOS via the Mobile Client, you would first have to start the business application from the overview list. From there on out, you have full access to the local SQLite database via the respective Cordova plugin as is defined in the JS scope of the web application that is running on the device. That’s why the information found on the documentation page from your second link isn’t contradicting the info box placed on the page from your first link and neither does Christian’s reply.
