Version 1.4.3 · 2026-10-07
THANKS EVERYONE! UPDATE: • Start Sync with Host AUv3 for Sequencers and Arp. You can turn off/on on SEQ Panel • App now Supports all the way back to MacOS 12.0 (Intel & Silicon) • Improve Voice Over/Accessibility PLUS ALL 1.4.x UPDATES: Better Preset Sync. And Import now works on Mac. However, you don't even need to import your banks into the Mac version. It will happen automatically if you do this: "Preset Sync" must be turned on separately on each device in the About page (the button in upper right of app header) Open the standalone app on your iPad and turn on the Preset Sync button. Choose Enable Sync when prompted. Repeat these steps in the standalone app on your Mac. Both devices…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
