The Asian and European apps of the WSJ can be accessed by all users, along with the US version, when launching the app using the edition selector feature.
Readers will also be offered the option of saving their favourite articles and sections, be able to watch videos and slideshows and access market data.
The WSJ launched its existing iPad app for its flagship US edition in April this year.
The latest European and Asian extensions will be free to download to access a certain amount of content. However, a subscription is required for full access to all the subscriber content.
