Retention
See how many users come back over time, grouped into cohorts by when they first showed up.
Retention answers the question every product team cares about: do people come back? Logspot groups your users into cohorts — everyone it first saw on the same day — and measures what share of each cohort returned on the days that followed.
How It Works
A cohort is the set of users who share a first-seen day. For each cohort, retention measures the percentage who came back and did anything on a later day:
- Day 0 is the cohort's first day and is always 100% (everyone was active when they joined).
- Day 1, 2, 3… show the share of that same cohort who returned that many days later.
Averaged across cohorts, those points form a retention curve. A curve that keeps falling means users try the product and leave; a curve that flattens (stops dropping) means you've found a group of people who keep coming back, which is the signal of product-market fit.
Retention is computed from your events, so there's nothing extra to instrument beyond tracking them. Identifying users makes it more accurate: without it, a person who returns on a different browser or device counts as someone new.
View Retention
The User Retention widget on your Logspot dashboard plots the curve for the last 30 days of activity, from day 0 through day 30. Hover any point to see the retention percentage and the number of users behind it.
