Frequently asked questions
Why does ToneEQ say software EQ is unavailable?
Protected Apple Music audio is played by Apple’s MusicKit platform player. iOS does not give ToneEQ access to that decoded audio, so software EQ is unavailable. Import a supported local audio file or use an included test sound to use ToneEQ’s audio engine and EQ.
Why did my profile not load on another headphone?
The free version keeps one automatic profile bound to one device. A new device starts Flat until you explicitly move the binding. Pro can keep profiles for multiple devices, while still ensuring only one final EQ is applied at a time.
How do I restore purchases?
Open ToneEQ Settings, choose Subscription, then Restore Purchases. Purchases are associated with your Apple Account and managed by the App Store.
How do I delete synced profile data?
Use Settings → Data & Privacy inside ToneEQ to remove local data and request removal of supported cloud profile data. You can also email the address above for help.
Response and availability
