How the Pro Purchase Works
Is there a subscription?
No. CompoundFX has no subscription: Pro is a single in-app purchase that you buy once. Nothing renews and nothing is billed again.
Can my family use Pro?
Yes. CompoundFX Pro supports Family Sharing, so the people in your Apple Family Sharing group can use Pro on their own iPhones without buying it again.
How do I restore Pro on a new iPhone?
Use the Restore Purchases control in CompoundFX. Sign in to the App Store with the same Apple Account you bought Pro with, open the app, and tap Restore Purchases.
Do I need an account?
No. CompoundFX has no accounts: the App Store handles the purchase, and everything else runs locally on your device.
Get CompoundFX
iPhone app, iOS 17 or later. Start free, and add Pro from inside the app whenever you need it.
