Support

Need a hand with Guitar Scale Finder? Email hi@doublecolourless.com and we'll get back to you, usually within two working days. In the app you can also tap Settings → Get help.

It helps if you tell us your device (iPhone, iPad or Android), the app version (shown at the bottom of Settings) and what happened.

Subscriptions

I paid but the app is asking me to subscribe

Tap Restore on the subscribe screen. Make sure you're signed in with the same Apple ID or Google account you subscribed with. If it still doesn't unlock, email us with the order number from your App Store or Google Play receipt.

How do I cancel?

Subscriptions are handled by Apple and Google, so you cancel there:

• iPhone and iPad: open Settings, tap your name, then Subscriptions, and choose Guitar Scale Finder.
• Android: open Google Play, tap your profile, then Payments & subscriptions → Subscriptions.

Cancel at least 24 hours before a free trial or billing period ends to avoid being charged. Deleting the app doesn't cancel a subscription.

Can I get a refund?

Refunds are handled by Apple and Google, not by us. On iPhone and iPad, request one at reportaproblem.apple.com. On Android, follow Google Play's refund steps.

Using the app

Magic Listen doesn't find the key

Magic Listen is on iPhone and iPad with iOS 27 or later. Play the song out loud near your device for a few seconds, ideally a part with the chords rather than just drums or vocals, and allow microphone access when asked. If it isn't sure of one key, it filters the scales by the notes it heard instead.

No sound when I play a scale or chord

Turn up the media volume, and check the sound isn't going to headphones or a Bluetooth speaker you've connected.
