Apple launched a beta version of a mobile app analytics service to provide app makers with insight into how their product is performing.

The company is inviting developers to request early access to the service, which will be granted on a first-come, first-served basis.

Apple’s App Analytics will include data about how often users visit the app’s page on the App Store and details of in-app purchases sales, as well as enabling developers to create custom campaign links.

Participating developers can view analytics data on the iTunes Connect homepage.

The move has been expected ever since the company acquired Burstly in 2014, the owner of still operating app test platform TestFlight, as well as a mobile analytics solution called FlightPath which was shut down before the acquisition.
