Purchases & Restore
Knob16 is free to download. Knob16 Pro is a one-time in-app purchase processed by Apple. It is not a subscription.
- To get Pro on another iPhone or iPad, sign in with the same Apple Account and tap Restore Purchases in Settings or on the Pro screen
- Family Sharing is not supported for Knob16 Pro
- Refunds are handled by Apple: request one at reportaproblem.apple.com
- If Pro is refunded, Pro features stop working, but your presets stay on the device and in iCloud
- Bluetooth MIDI, Live Mode, and Grouping Mode each include three free 24-hour trials; a trial never charges you

- A short description of the problem
- What you were trying to do
- Your device model and iOS/iPadOS version
- Whether you were using USB, Bluetooth MIDI, or Wi-Fi MIDI
