Today Apsalar announced the release of two new components of its ApScience analytics suite for mobile applications: engagement index & revenue analytics. These new metrics will allow Apsalar clients to gain greater insight into how users are interacting with their application. It will also make it possible for users to be segmented based on the amount they spend in the app. You might be as surprised as I was to learn that this is a competitive space characterized by big data and advertising revenues. Apsalar hits all the bases with SDKs for Android, iOS, and a RESTful API.
