For writers
At this time, the option for free readers to upgrade and become paying subscribers isn't available for most publications on the Substack iOS app.
However, as part of a pilot program, some readers may be able to pay for subscriptions to select publications directly within the Substack iOS app via Apple’s built-in payments system.
We’re hoping to expand the pilot program to more publications in the coming months. If you have payments enabled on your publication and are interested in joining, please fill out this form here.
