___________allow you to further define your App Activity Custom Audience based on the frequency and rec en cy of user actions.

App Activity Combinations allow you to refine your App Activity Custom Audiences by setting conditions based on the frequency (how many times an action occurred) and recency (how recently an action occurred) of user actions within your app. This enables highly targeted advertising, for example, reaching users who have opened your app five times in the last seven days but haven't made a purchase. Twitter Custom Audiences is a broader term for various audience types, not the specific tool for frequency and recency. Promoted Video Ads are an ad format, not an audience targeting feature.
