I believe the value of the app is in learning how all those musical block work and interact together, how to recognize them by ear and visualize them on the neck so you can incorporate them in your playing rather than an app to learn the technicality of the guitar.

As for my own playing, as stated in another comment it has quite suffered from my lack of practice due to the time spent on making this...
