Cohort analysis was a game-changer for us. We grouped users by acquisition date and tracked their behavior over time. Revealed a bunch of stuff we missed before.
For example, we found users who completed the onboarding tutorial in the first 48 hours had way higher retention. So we tweaked our push notifications to nudge more people through it early.
Heat maps also showed us some UI elements nobody was using. Cut those out, simplified the interface, and saw engagement tick up.
One surprising find: digging into time-of-day usage patterns. Turned out a lot of our power users were night owls. We started timing certain features and promos for late evening and saw better results.
Key thing is to keep experimenting with how you slice the data. Sometimes the gold is hiding in weird combinations of metrics you wouldn’t think to look at together.
