Getting statistics out of your app might prove to be one of the most valuable resources you will encounter. Statistics will support your product decision making by providing real user usage data, including showing how users actually interact with your product, where do they drop off, what product abilities are completely ignored and so on.
We recommend using a web analytics service to collect and analyze app data, measure user engagement and improve monetization.
Our preference is the industry standard Google Analytics.
We highly encourage you to take the time to implement any chosen analytics service thoroughly.
