Cohort analysis is a good metric on how users engage to an application. To do this, you:
- Break the users into cohorts according to when they register (bin size usually a month)
- Count the number of users in each cohort who login in over time
- Plot it
What you can get:
- the number of users currently using the program (read the height of period 5)
- retention rate over time
- growth rate
EverNote ECO Phil Libin used this analysis to attract investors.
How to make the cohort analysis plot?
It’s actually simple. Use Excel. Prepare a table where each row is one cohort over time, and each column is a time point. Then click “insert” and “Stacked Area”.

Try Stork, a research tool we developed
Stork is a publication alert app developed by us at Stanford. As a researcher we often forget to follow up important publications - and it's practically impossible to search many keywords or researchers' names everyday. Stork can help us to search everyday and notifies us when there are new publications/grants. How Stork helped me?
