What's New in What About Phase?
1.22
October 28, 2026
All ten processes are also AUv3 plugins for AUM, GarageBand and other hosts — each as an instrument and as an effect, with the wheel as the plugin's screen. They come with Pro, a one-time purchase that also includes the full version; tap the AUv3 badge beside the title to see it. New in this update: a Redeem code button on the unlock screens, for offer codes (iOS 16.3 or later). Since 1.20: every plugin has a Level control, on the effects BAR now keeps the loop at one bar as your host's tempo changes, and “Restore purchase” checks with the App Store first and tells you what it found.
