Is AirBuddy a subscription?

No. An AirBuddy license purchased from the official website is a one-time purchase for that major version of the app. It includes all features in that version and at least one year of updates with new features and bug fixes.

AirBuddy is also available through Setapp, which requires an active Setapp subscription.

AirBuddy 3 is a paid major upgrade and requires an AirBuddy 3 license. An AirBuddy 2 license remains valid for AirBuddy 2.
