Lean Mobile App Development

Pirate metrics (AARRR)

We can make improvements only if we have insight into the optimization process. If we want to learn from the process, we need to measure it. The conversion is something that we are going to measure in another chapter. There we will take a closer look at actionable metrics that we can apply to mobile app development.

These so-called pirate metrics (AARRR, apparently that is what pirates say) perfectly describe why the onboarding flow is so important and what each phase represents in the conversion funnel. In short it goes like this:
