Nothing is more challenging for businesses than to engage the users and retain them, despite many app downloads, and how to boost the app performance today. In the struggle to resolve user engagement & retention and app performance issues, mobile app analytics is regarded as the authentic rescue system. Though app analytics tools are robust and offer insightful details about the app-user association, at times, they turn out to be an obstacle for mobile app developers and stakeholders for several reasons.
