Need help with Sound Pro? Have a bug to report or a feature you'd like to see? We'd love to hear from you.
Open Sound Pro, go to Settings, and tap "Restore Purchases." Make sure you're signed in with the same Apple ID used for your original purchase.
Subscriptions are managed through your Apple ID, not inside the App. On your iPhone, go to Settings → your name → Subscriptions, select Sound Pro, and cancel there.
The Meter tab uses your microphone to measure ambient noise levels in real time. Audio is processed entirely on your device and is never recorded or sent anywhere.
Volume boost amplifies your device's audio output beyond its normal limit, which can introduce distortion at very high boost levels or on small speakers. Try lowering the boost percentage or using headphones for cleaner sound.
