Mobile analytics company adeven has launched version 2.0 of its adjust.io SDK, intended to help developers transition over to iOS 7.
In response to Apples move to IDFA, the update brings offline tracking, enabling developers to see how users interact with their app even without a data connection.
The open source SDK can be used to track a whole host of metrics, from clicks and installs to more complex performance indicators including average revenue per user and retention. 
adjust.io is available for free here.
