Podcast apps like Apple & Spotify collect their own metrics for the number of listens your podcast receives, which may differ from our own (which follow the IAB 2.1 Podcast Measurement Guidelines).
Here's how they define a listen or play:
Starts - measured when a Spotify user listens to 0 seconds or more of any episode in your catalogue
Streams - measured when a Spotify user listens to 60 seconds or more of any episode in your catalogue
Listeners - number of unique Spotify users who started an episode in your catalogue
Listeners - The number of unique devices that have played more than 0 seconds of an episode
Engaged Listeners - The number of unique devices that played at least 20 minutes or 40% of an episode within a single session. Pausing or stopping an episode does not count as starting a new session
Plays - The number of plays on unique devices where the play duration is greater than 0 seconds.
