Nice app. Lots of functionality. Maybe another thing which would be useful would be the option to select other tunings for the guitar visualisation such as Drop D, DADGAD etc.

Please note the folowing. The devellopper of this app resolved the issue reguarding the information about the missing features. These features are not available as discribed by the manual. This is because this is the light weight version and needs other companion tools This is now explained in the manual and therefore all features in this app works as they should. Before purchissing this app download it and read thru the updated manual and make sure its what you need. Thanks

Dear Corrie, the composer feature is not part of this app. Features available to the VIP users are mentioned in the VIP Membership screen. There was a confusion in the user manual which we have corrected now. We thank you for pointing out the confusing part. Hope we served you well. Keep exploring🎶

its good and I paid for the VIP, but the problem is the settings always show a blank screen, so no settings and the ad screen on the bottom blocks the piano keys and never disappears, even after I pay for the VIP No Ads. These things need to be fixed. And I have an android phone.
