[FREE] New App : player for guitarists

Hello I introduce myself I am Francis, beginner guitarist, 50 years old.
I allow myself to post here because I created an Android application, AB Music Trainer, because I could not find any simple app to train on guitar.
It is actually an audio video player that allows you to create loops and train on these loops on backing tracks or on originals.

Take a look, I think it might interest you. The free version is fully functional and ad-free, while being limited to 3 loops per track.

Thank you.
Musically, Francis.
