Countly is built to help you better understand your user’s behavior. To accomplish that, you’ll want to track your user’s actions in detail.

Whenever you call track from our iOS or Android library, we’ll record an event with Countly. track takes the name of the event and any optional properties you want to associate with the event.

Custom Events

All you have to do is make a track call to send a custom event to Countly. The event name will map to the countly “key” and we automatically set “count” to 1. If you add properties to the event those will be passed to Countly as well.


It’s easy to track revenue in Countly through Segment. All you have to do is use our track method with a property labeled revenue. The value must be a number.
