Shred, The ultimate Guitar toolkit

Every day I use the apps on my phone to tune my guitar and choose tempos for my daily practice.
I have never really thought about how they work or wanted to change anything about them, But my recent struggle with playing faster made me wonder if they can do more.
And it resulted in this concept of a motivating path to a more shreddy practice :)
