Build a usage interval analysis

A usage interval analysis is related to a retention analysis, but works a little differently. While a simple retention analysis measures the amount of time between a starting event and a return event, a usage interval analysis considers return events only. It shows how long users go between triggering your product's most important event, its critical event.

For more details on usage interval analyses and what they mean, refer to the Help Center article on interpreting your retention analysis.

To build a usage interval analysis, follow these steps:

1. In the Measured As module, click Usage Interval.
2. In the Events Module, select the return event. This should be your product's critical event.
3. To add properties to your return event, click + Filter by, select the property name, and specify the property value you're interested in.

4. In the Segmentation Module, identify the user segment you want to include in this analysis. You can import a previously saved segment by clicking the Saved dropdown and selecting the one you want from the list. Otherwise, Amplitude assumes your analysis targets all users.
5. If you don't want to import a previously saved user segment, build your own by adding properties. To do so, click + Filter by, choose the property you want to include, and specify the property value you're interested in.
6. To narrow your focus further, tell Amplitude to include only users who already performed certain actions. To do so, click + Performed and choose the event you're interested in.
7. To add another user segment, click + Add Segment and repeat steps 5 and 6.

Your usage interval analysis appears, along with a tabular view of your results.
