Every creator on Playbook gets their own unique link. Here is an example:
https://my.playbookapp.io/magnus-lygdback
This link pulls info from your channel - your picture, bio, latest workouts, etc and hosts them in a good-looking splash page where all your customers can sign-up via credit card - bypassing Apple and Android's 30% fee.
If a user subscribes to Playbook through your link, you keep that user's subscription for the life of the user. Regardless if they are following other trainers on Playbook.
If a user does not come through your link, you get paid based on the amount of time the user is watching your content just like Spotify or Netflix.
When a user clicks the link: They go to your splash page to learn more about your offering > The app downloads > Automatically plays your intro video > Every time the user opens the app, it opens to your channel first
