User Cohorts

Cohorts let you group users into meaningful segments, like country or user tenure, so you can see what’s working (and where). devgrowthlab automatically creates some of these groups for you, and you can add your own right from the dashboard.


To manage your cohorts:
Go to Settings → Cohorts in your devgrowthlab dashboard.

You’ll see existing cohort categories and can add new ones.

Two cohorts (user tenure and country) are automatically created for every project.

Groups users by how long they’ve been active since you first sent an event to devgrowthlab.

LabelDescription
First InstalledNew installs
Day 1First full day after install
Day 2–7Early engagement phase
Day 8–28Regular active users
Day 29–90Retained users
Day 90+Long-term loyal users

Determined by the country where the data entered our network. We don’t store personal or identifiable information (like IP addresses), so this country assignment is an approximation, designed to stay fully privacy-compliant.


You can create additional cohort categories in the same dashboard For each one, specify the maximum number of cohorts you’d like to track. For example, “Top 3 app versions” or “Top 5 subscription plans”.

Check out the guide on custom cohorts to send the right data.

devgrowthlab automatically highlights the most important cohorts using exponentially decaying averages. This means your dashboard always shows the most up-to-date insights without needing to manually refresh definitions.


For each cohort, devgrowthlab provides:

  • Up-to 28 days of daily active user (DAU) history
  • 1-, 7-, and 28-day DAU forecasts
  • Automatic email alerts if a cohort is performing above or below forecast
  • Recommendations in the dashboard to guide your next steps

You can view your cohorts visually in the dashboard or head to Dashboard → Recommendations for actionable insights.


Cohorts can help you make smarter, data-driven decisions, without being a data scientist.

If DAU drops in one country, your alert might highlight that region. You could check if:

  • Ad performance changed
  • Retention dipped due to competitor features
  • An update affected local users

If one market or feature suddenly grows, the Recommendations tab will help you identify what might be driving that success, so you can replicate it elsewhere.


Each plan includes a maximum number of distinct cohorts that can be tracked and forecasted at any one time. Higher tiers support more simultaneous cohorts. (See Pricing & Usage for details.)

Cohorts update once per day.


devgrowthlab turns complex retention analysis into something you can understand and act on - even if you’ve never built a dashboard before. It’s analytics that fits how real developers work.
