Time Out editions
Which edition you choose is up to you; the features are basically the same for each.
The direct edition can be downloaded from the Time Out website, and updated from within the app. If you choose to become a supporter, payment is handled either via an in-app purchase powered by FastSpring, or the Dejal Store online.
The Setapp edition can be downloaded and updated from the Setapp status menu or application. There is no supporter payment needed for this edition; your Setapp subscription includes all supporter rewards.
The Mac App Store edition can be downloaded and updated from the Mac App Store, of course. The optional supporter payment is handled via your Apple ID with an in-app purchase.
