Retention Analysis

You can use Keen to figure out if people like your app and keep using it over time. Retention analysis works by determining how many entities that do an activity in a given week do an activity in subsequent weeks. For example, retention analysis can help you answer questions like:

  • What percentage of your new users from last week came back and used your app this week?
  • What’s your retention rate at 5 weeks? 15 weeks?

For more info on how retention analysis works, checkout the blog post How to Do a Retention Analysis.

Below are a few example methods for analyzing retention:
