SimplyGuitar is nice! It really helps you learn chords, how to position your fingers, how to tune your guitar, and more! Thing is, there are a lot of flaws in SimplyGuitar , especially when it comes to receiving sounds. Sometimes when I try to tune the sound, it gives off different responses and I never know if my guitar is in tune or not! Not only that, but when strumming, it usually gets marked red and it keeps making me think I’m doing something wrong. Because of this, I try strumming louder, even if the phone is directly next to or in front of me. Because of me strumming louder, this caused blisters for me to form on my fingers, simply to just get all of the notes to blue and receive perfectly. Even I, a beginner guitarist, know that I should not be able to strum or hold my notes so hard to the point where I have blisters form all over my fingers only to get all of my notes blue. I’ve even asked my brother, a person who’s played guitar in the past, if it was normal to have blisters only for him to respond with, “No, you’ll only be causing unnecessary damage and pain to your fingers.”. Overall, SimplyGuitar is nice, and I’m happy I get to learn trending songs! I just hope you fix your sound system.
