Apple’s new app analytics tool is now available to all registered iOS developers, the company said today.

Apple had recently opened the new tool to a handful of developers who requested it. Today the tool is available through the iTunes Connect interface to everyone.

App developers can use the analytics tool to learn things like how customers made their way to finding and downloading their app. They can access data on how long people continue using their apps. They can see how many views their App Store page is getting, and where the traffic is coming from.

All this will help them fine-tune their development and marketing efforts, an Apple rep told VentureBeat.

iOS app developers have been waiting a long time for an analytics tool from Apple. Apple tightly controls the customer behavior data from the App Store, and doesn’t share it with third-party analytics firms. So, in a sense, Apple is the only game in town.

Apple acquired an app analytics company called Burstly (and its products TestFlight and FlightPath) last February, and it was only a matter of time before Apple started to offer the analytics tools it got in the deal.

The cost of the analytics tool is included in the cost of the Apple Developer membership fee.
