Mixpanel is very strong at tracking mobile app optimization and analytics, as well as push notification A/B testing. Many developers like Mixpanel, with the only caveat being that there are usability and documentation shortfalls. The reports and charts that come from Mixpanel are a strong point of this platform. I’ve seen them used everywhere from SlideShare on LinkedIn to investment decks presented to Venture Capitalists. Those who get the most out of this tool have created optimized workflows. Less than 0.1 percent of sites utilize Mixpanel as an analytics platform.
